Anthropic OpenAPI spec

Repository created while waiting for the official OpenAPI spec from the Anthropic.

Versions

There are a few versions of the specifications.

hosted_spec.json

(Recommended) Specification taken from Antrhopic's official TypeScript SDK - https://github.com/anthropics/anthropic-sdk-typescript/blob/main/.stats.yml. Unfortunately, it isn't "officially" exposed, nor easy to find, so this repo aims to help point at it.

Actually, this file is slightly modified. How exactly, check the fix_spec.py. The modification is adding missing "X-API-Key" param to header which is required according to Anthropic's doc but it's missing in the file.

hosted_spec_v3.0.0.json

In case you can't use OpenApi spec in version 3.1.0, then this is your next step. The spec is created via downgrade_spec.py. Specifically, all "type": "null" were removed (in favour of "nullable": true) and prop const from enums was removed.

stiched_spec.yaml

The spec is semi-automatically created by pointing Perplexity to each page on https://docs.anthropic.com/en/api/ and asking to generate the spec. Then, all were stitched together and eye-balled verified.

F.A.Q.
