### [How to Confirm Phone Number Ownership with Lookup Identity Match in Python](https://yomu.fyi/post/how-to-confirm-phone-number-ownership-with-lookup-identity-match-in-py.md)
- Company: [Twilio](https://yomu.fyi/company/twilio.md)
- Author: Kelley Robinson, Dylan Frankcom
- Published: Aug 28, 2026
- Type: Tutorial

The tutorial shows how to use Twilio Lookup Identity Match in Python to confirm that signup information is associated with a phone number and reduce signup fraud. It builds a Flask application that accepts an E.164-formatted number, first name, and last name, then calls the Lookup API with fields="identity\_match" and the supplied identity attributes. The response exposes statuses including exact\_match, high\_partial\_match, no\_match, and no\_data\_available; the example accepts a result only when the number is valid and both names are exact or high partial matches. The implementation covers project setup with Flask, twilio, and python-dotenv, environment-based credentials, an intl-tel-input form, and frontend handling for success and failure messages. It also notes that Identity Match can use combinations of name, address, national ID, or date of birth, and points to other Lookup packages such as Line Type Intelligence and SIM swap detection.


### [Introducing 100K context windows](https://yomu.fyi/post/introducing-100k-context-windows.md)
- Company: [Anthropic](https://yomu.fyi/company/anthropic.md)
- Published: Aug 26, 2026
- Type: Announcement

Claude’s context window has expanded from 9K to 100K tokens, or about 75,000 words, enabling businesses to submit hundreds of pages and sustain conversations for hours or days. The announcement describes using the larger window to digest documents, synthesize information across multiple files, answer questions, and work with full codebases, with the claim that complex questions may perform substantially better than vector-search approaches. In a test, Claude-Instant processed the 72K-token text of The Great Gatsby after one line was altered, identified the change correctly, and responded in 22 seconds; 100K tokens is also described as roughly six hours of audio. The capability is available through the API, with examples including financial analysis, legal review, developer-documentation search, podcast summarization, and rapid prototyping.


### [The Email Verification API](https://yomu.fyi/post/the-email-verification-api.md)
- Company: [Resend](https://yomu.fyi/company/resend.md)
- Published: Aug 25, 2026
- Type: Tutorial

The proposed Email Verification API lets a browser verify that a submitted email address belongs to the user without sending them away from the current form to retrieve an OTP or magic link. Its flow involves the user, browser, mailbox provider (issuer), and application server (verifier): after mailbox registration, the browser and issuer create a token that is submitted with the address and checked server-side. Implementation requires an email input, a hidden email-verification-token input with a session-bound random nonce, and token verification using the site origin as audience; a JavaScript package handles parsing, lookups, and signature checks. The proposal is currently limited to Chrome’s origin trial and Gmail mailbox verification, so the source recommends progressive enhancement and other verification APIs where unavailable.


### [Video Call Integration on Different Platforms](https://yomu.fyi/post/video-call-integration-on-different-platforms.md)
- Company: [Twilio](https://yomu.fyi/company/twilio.md)
- Author: Donal Toomey
- Published: Aug 20, 2026
- Type: Tutorial

Video calling can add direct, personal communication to customer and patient interactions without moving conversations to a third-party app or website. The post outlines an integration path based on choosing a platform, selecting development-specific SDKs, and either building a custom application or deploying and adapting an open-source one. Twilio is presented as a cloud communications platform offering APIs, SDKs, reference apps, and documentation, with SDKs for JavaScript, Android, and iOS; listed build examples also use Svelte, Go, Python, ASP.NET Core, Angular, Node.js, TypeScript, and Express. Open-source options provide features such as screen sharing and network-condition monitoring, while Twilio Video supports branded virtual backgrounds and layouts, but the source does not report implementation results.


### [Hello, Ireland! Sending SMS in Twilio’s Ireland Region](https://yomu.fyi/post/hello-ireland-sending-sms-in-twilio-s-ireland-region.md)
- Company: [Twilio](https://yomu.fyi/company/twilio.md)
- Author: Gary Spencer
- Published: Aug 18, 2026
- Type: Tutorial

Twilio’s Ireland region, IE1, provides EU data residency for Programmable SMS, keeping personal data such as recipient phone numbers and message bodies in the EU through the supplier edge. Adopting it requires separate IE1 credentials and an IE1 Messaging Service, while US1 Messaging Services cannot be reused; SMS to and from +1 numbers, RCS, and WhatsApp are not currently supported. For API calls, the main code change is replacing api.twilio.com with api.dublin.ie1.twilio.com, while client SDK users switch the region parameter from us1 to ie1 and can retain the Dublin edge. Twilio’s logs include a region filter to verify where messages were processed, and the post notes that Studio and TaskRouter support in IE1 is still an initiative.


### [Model routing with Google Cloud API Gateway](https://yomu.fyi/post/model-routing-with-google-cloud-api-gateway.md)
- Company: [Google](https://yomu.fyi/company/google.md)
- Author: Mak Ahmad, Sanjay Pujare
- Published: Aug 4, 2026
- Type: Tutorial

Google Cloud API Gateway adds model routing in Public Preview for AI applications that need to direct traffic among models without hardcoded endpoints or open-source proxies. The serverless ingress layer accepts OpenAI-compatible requests and uses routing rules in an OpenAPI 3.x specification, where x-google-api-management defines backends and routers map virtual model names to targets such as Gemini, Claude, or OpenAI OSS-GPT. After deployment, clients call a stable endpoint; the Gateway transcodes the request to the backend’s native schema, adds an Agent Platform authentication token, and forwards it, separating client authentication from provider credentials. The guide also notes that every backend in one router must share a host, and shows standalone routing alongside possible Agent Gateway integration for security governance.


### [Kimi K3: the complete developer guide](https://yomu.fyi/post/kimi-k3-the-complete-developer-guide.md)
- Company: [Together AI](https://yomu.fyi/company/together-ai.md)
- Published: Aug 1, 2026
- Type: Tutorial

Kimi K3 is presented as Moonshot AI’s 2.8-trillion-parameter open-weights model for long-horizon coding, end-to-end knowledge work, and deep reasoning, served through Together AI’s OpenAI-compatible API. Its architecture combines Kimi Delta Attention (KDA), Attention Residuals, and Stable LatentMoE, which activates 16 of 896 experts per token—roughly 2%—and supports a 1M-token context. The implementation guide shows Python calls for configurable reasoning effort, reasoning-free instant mode, streaming, multi-image vision, strict JSON-schema output, and function tools, while noting automatic prefix caching. It also covers production-oriented details such as generous max\_tokens for reasoning-heavy structured output, a 100 MB request-body limit for vision, tool-call history handling, and deployment from US infrastructure.


### [Introducing Claude Opus 5](https://yomu.fyi/post/introducing-claude-opus-5.md)
- Company: [Anthropic](https://yomu.fyi/company/anthropic.md)
- Published: Jul 25, 2026
- Type: Announcement

Claude Opus 5 is available as a new model positioned near the frontier intelligence of Claude Fable 5, at half its price, while remaining behind Mythos 5 on cybersecurity tasks. Reported results show state-of-the-art performance on coding and knowledge-work evaluations, including Frontier-Bench, alongside strong results on ARC-AGI 3, Zapier AutomationBench, and OSWorld 2.0. The model uses configurable effort settings to trade intelligence for token use, speed, and cost, and is described as stronger at verifying work, iterating, and handling long agentic tasks. It costs $5 per million input tokens and $25 per million output tokens, with Fast mode running about 2.5 times faster at twice the base price. Safeguards allow vulnerability finding while blocking binary-based scanning, penetration testing, and exploit generation, with flagged requests able to fall back to Opus 4.8.


### [Introducing Claude Opus 4.8](https://yomu.fyi/post/introducing-claude-opus-4-8.md)
- Company: [Anthropic](https://yomu.fyi/company/anthropic.md)
- Published: Jul 22, 2026
- Type: Announcement

Anthropic introduces Claude Opus 4.8, an upgrade over Opus 4.7 for coding, agentic skills, reasoning, and practical knowledge work, with regular pricing unchanged. The release adds adjustable effort in claude.ai and Cowork, dynamic workflows in Claude Code, fast mode at 2.5× speed, and support for system entries inside the Messages API messages array. Dynamic workflows can plan work, run hundreds of parallel subagents in one session, and verify outputs; the post cites codebase-scale migrations across hundreds of thousands of lines as an example. Early evaluations and tester reports describe stronger reliability, judgment, tool efficiency, computer use, and analysis, including an approximately fourfold reduction in allowing flaws in generated code to pass unremarked.


### [How Verifiable Digital Credentials Are Reshaping Trust Architecture](https://yomu.fyi/post/how-verifiable-digital-credentials-are-reshaping-trust-architecture.md)
- Company: [Okta](https://yomu.fyi/company/okta.md)
- Author: Akanksha Bhasin
- Published: Jun 29, 2026
- Type: Explainer

Verifiable Digital Credentials (VDCs) are presented as a new trust layer for applications that need to verify claims such as age, licenses, employment, or eligibility without collecting documents and excess PII. The model uses an Issuer-Holder-Verifier trust triangle: authorities sign credentials, users hold them in wallets, and applications request specific proofs, with selective disclosure limiting exposed data. The standards stack combines SD-JWT VC or mdoc credential formats, OpenID4VCI for issuance, OpenID4VP for presentation, and the W3C Digital Credentials API for browser-wallet invocation. Production verification also requires issuer trust lists, trust-framework integration, and key rotation, not merely signature checks. Because browser API rollout is still progressing, the recommended baseline is redirect-based OpenID4VP with the Digital Credentials API added as a progressive enhancement, starting with one bounded verification use case.

- Company: [Uber](https://yomu.fyi/company/uber.md)
- Published: Jun 22, 2026
- Type: Announcement

Uber Advertising is introducing Uber Marketing Manager as a self-serve platform intended to unify advertising across Uber and Uber Eats, building on Ads Manager for restaurants. It also outlines Creative Studio expansion, new APIs, and a Mastercard Commerce Media partnership designed to connect campaign activation, offers, measurement, and real-world experiences across consumer journeys. Examples include Krispy Kreme’s Destination Offers campaign in Mexico, Molson Coors’s multi-format soccer campaign, and adidas’s pan-European Journey Takeover. Creative Studio will expand to Australia and Brazil in 2026, followed by continued expansion across LATAM, EMEA, and APAC throughout 2027. Uber says its connected approach is intended to help advertisers engage consumers across Uber, Uber Eats, and beyond, while a third-party validated Affinity Solutions study found a 27% incremental lift in sales across all channels and a 5% lift in brick-and-mortar sales for Sponsored Listings on Uber Eats.


### [Case study: TriMet unlocks same-day paratransit with an innovative partnership](https://yomu.fyi/post/case-study-trimet-unlocks-same-day-paratransit-with-an-innovative-part.md)
- Company: [Uber](https://yomu.fyi/company/uber.md)
- Published: Jun 16, 2026
- Type: Problem & solution

TriMet’s 2024 partnership with Uber, TransDev, and Trapeze added same-day capability to its LIFT paratransit service in Metro Portland. Before LIFT+, trip management spanned multiple systems, while cancellations and manual coordination increased operational burden and weakened the rider experience. In April 2024, riders began booking through LIFT’s web platform or call center, after which TriMet’s integrated Trapeze PASS TripBroker used the Uber Plug-in to select dedicated vehicles or Uber based on rider profiles, requests, trip efficiency, and fleet capacity; it could also reschedule cancellations and delays. Since launch, TriMet has delivered more than 47,300 Uber trips and reduced average cost per trip from $78 to $54, while riders gained same-day flexibility and trip details including estimated arrival times.


### [How to make the case for giving your AI Agent system access](https://yomu.fyi/post/how-to-make-the-case-for-giving-your-ai-agent-system-access.md)
- Company: [Intercom](https://yomu.fyi/company/intercom.md)

- Type: Problem & solution

AI Agents can answer support questions without backend access, but they cannot complete changes such as payment-plan updates, claims, or account edits. Connecting an Agent to CRM, billing, order-management, or other systems moves support from explanation to end-to-end resolution, and the source frames that shift as the basis for an engineering request. Data from a 2026 Customer Service Transformation Report shows improved metrics among 87% of teams with mature AI deployment, versus 62% overall, while only 10% report reaching that stage; an internal comparison found Procedures with system access produced the largest gains in workflows requiring judgment, branching, live data, or handoffs. The recommended case starts with one high-volume, repeatable workflow, maps its data and actions, and defines a narrow pilot. Teams can then progress from no integration to read-only access and finally write actions, using measured results to justify further work.


### [Extending Fin as the most open Agent platform](https://yomu.fyi/post/extending-fin-as-the-most-open-agent-platform.md)
- Company: [Intercom](https://yomu.fyi/company/intercom.md)
- Author: Paul Adams
- Published: Jun 9, 2026
- Type: Announcement

Fin is being made available as a Service Agent on top of HubSpot and Freshworks, allowing HubSpot and Freshdesk customers to deploy it without migrating from their helpdesk. The announcement says customers can get it integrated and live in less than an hour across voice, email, chat, social, and other channels, with a stated 76% average resolution rate. Fin is described as handling complex queries that require reading and writing to third-party systems, while remaining configurable to each business’s policies; its openness includes APIs, MCPs, a CLI, access to the Apex trained model, and public product, help-center, and developer documentation. The broader argument is that open Agent platforms let customers experiment, replace components, and avoid vendor lock-in, with competition determined by product quality.

- Company: [Okta](https://yomu.fyi/company/okta.md)
- Author: Emily Wendell
- Published: May 12, 2026
- Type: Tutorial

Okta’s API Integration Actions let independent software vendors build Provisioning, Entitlements, and Universal Logout integrations in the Okta Integration Network using Workflows, Okta’s low-code builder. The approach maps existing APIs directly to Okta action contracts, allowing developers to avoid building and maintaining a SCIM server while translating API calls into formats Okta can consume. The guide walks through creating an OIN integration, configuring tenant and authentication mappings, adding API Integration Action components, building and validating flows, and submitting them through the OIN Wizard. It also explains how to create and update an org-only test instance before review, noting that submission changes do not automatically update an existing test instance for security reasons.


### [Welcoming Diel Duarte, our new Open source Engineer](https://yomu.fyi/post/welcoming-diel-duarte-our-new-open-source-engineer.md)
- Company: [Resend](https://yomu.fyi/company/resend.md)
- Published: Apr 30, 2026
- Type: Announcement

Resend introduces Diel Duarte as its new open source engineer, bringing more than 13 years of experience building web applications and SDKs. His focus is developer experience, especially API design with clean ergonomics that lets developers concentrate on building rather than wrestling with interfaces. Diel describes a path from studying programming and computer fundamentals at Cotemig to following Resend as a user and joining after an interview process he found unusually human; he cites Resend’s DX and craft, along with Zeno’s open source work, as major references. Outside work, he draws inspiration from deliberately curated feeds, new languages and APIs, visual-design communities, and creator friends, while keeping music and interior design as interests; he names Warp Terminal as his favorite tool and Japan as a memorable destination.


### [Custom Tracking Domains](https://yomu.fyi/post/custom-tracking-domains.md)
- Company: [Resend](https://yomu.fyi/company/resend.md)
- Published: Apr 16, 2026
- Type: Announcement

Resend has launched custom tracking domains, making the feature free for all users. Email tracking typically relies on shared domains, so another sender’s reputation can affect deliverability. Users configure the feature at the domain level by adding a required DNS record, after which Resend routes tracking through the custom domain; both click and open tracking are disabled by default. Click tracking records link clicks through redirects, while open tracking records image downloads from a 1x1 transparent pixel. Custom domains align tracking links with the sending domain, avoid unfamiliar recipient-facing domains, and can improve deliverability; API configuration accepts open and click tracking flags plus a tracking subdomain, while webhooks emit real-time open and click events.
