API Anything is an open source tool that learns a website's internal requests and exposes them as operations your agent calls over HTTP, with no browser. It shares what it learns in a common catalog. In my test, 6 of its 7 read operations answered in under 0.9 s; Google Flights failed from Europe.
Ollama 0.34.1 through 0.34.4 reject with HTTP 400 any request to /api/chat or /api/generate that carries typical_p in options, even at 1.0. The fix is to drop the field in the client, go back to 0.34.0, use the /v1 endpoint, or move to 0.40.0, which only logs a warning.
oMLX 0.7.2 listens on 127.0.0.1:8000 and serves OpenAI's API and Anthropic's Messages API on the same port. The key travels in Authorization: Bearer or in x-api-key and is mandatory as soon as the server listens beyond loopback. Errors come back in OpenAI's format, and the port changes with --port, OMLX_PORT or the server section of settings.json.
OpenRouter is a hosted gateway that gathers more than 500 AI models from over 80 providers behind a single OpenAI-compatible API. You change the base URL and use one key and one balance. You pay each model's rate with no markup, plus 5.5% when you buy credits, and gain automatic routing and failover.
Large language models have spent two years promising effortless documentation for code, APIs and architecture. After watching dozens of projects try it, clear patterns emerge for where it works and where it just becomes more debt.
