Orbit by Postman

Orbit, built by the Postman team, turns a natural-language task description into the right sequence of public API calls: it finds endpoints that fit, then generates integration instructions covering authentication, parameters, and the gotchas that usually cost an afternoon of forum archaeology. The positioning is explicitly agent-era: the output is designed so coding agents can discover, evaluate, and integrate public APIs, with install paths for Claude, Cursor, VS Code, and Codex or ChatGPT. There is an llms.txt endpoint for page-level indexing, which tells you the team expects machines to be a first-class audience alongside humans. The Postman pedigree matters here, since API metadata quality is the whole product and they have been maintaining exactly that kind of data for over a decade. For developers wiring third-party services into agents or scripts, this compresses the discover-document-integrate loop considerably, and the free access during launch makes trying it a low-cost experiment.
