A KDnuggets tutorial by Abid Ali Awan that walks through scraping thousands of pages with the Olostep Batch API in Python, downloading the results as Markdown and checking how many requests completed. Running the code requires an Olostep API key.
Developer documentation for Olostep's /v1/batches endpoint, which submits large lists of URLs for scraping in one job and returns page content such as Markdown or HTML, with request parameters, status polling and retrieval examples. Olostep is a paid web-data API; reading the documentation is free.
Quickstart documentation for AgentMail, an API that lets AI agents create and manage their own email inboxes, including agent self sign-up and sending and receiving email. Signing up is free for 3 inboxes and 100 emails per day; custom domains require a paid plan.
A technical article covering API authentication and authorization mechanisms such as API keys, OAuth, and JWTs, comparing their trade-offs and describing common failure modes engineers encounter when implementing them.
A developer blog post announcing that Meta is removing the Access Verification step from the Tech Provider onboarding flow, meaning developers who build apps that access client business data no longer submit a separate business review.
An open-source drop-in replacement for the OpenAI API that runs models on your own hardware, including CPU-only machines. MIT licensed.
From the site: LocalAI is the open-source AI engine. Run any model - LLMs, vision, voice, image, video - on any hardware. No GPU required. - mudler/LocalAI
Why I recommend it: Point existing code at your own server instead of a paid API — no code changes beyond the address.
One interface to hundreds of AI models with prices side by side, including a set of free models you can use without a subscription.
From the site: The unified interface for every model. Find the best models & prices for your prompts
Why I recommend it: Free to sign up and there are free models on the list; paid models are pay-as-you-go with no subscription.
Official OpenAI guide for designing prompts for Realtime voice models, including gpt-realtime-2 and gpt-realtime-1.5. Covers role definition, guardrails, tool delegation and iterative testing.
Why I recommend it: Start here if you are building voice agents or want cleaner spoken-AI interactions. The guide recommends starting minimal and adding rules only for behaviors that fail in testing.
