Both APIs are described in OpenAPI 3.1. These files generated every page of this reference, so they are the single source of truth.

Generate a client

# TypeScript client (openapi-typescript + fetch)
npx openapi-typescript https://developers.octolit.com/openapi/octolit-partner-api-v1.yaml -o octolit-partner.d.ts

# Any language (OpenAPI Generator)

  -i https://developers.octolit.com/openapi/octolit-trading-api-v1.yaml -g python -o ./octolit-trading

# Postman / Insomnia / Bruno: File > Import > the YAML URL

Live copies

Your own Octolit host serves the document that matches the version it runs (plus a plain-text broker guide at GET /api/external/v1/guide.txt and a reference page at GET /api/open/v1/docs). When they differ from the files here, your host wins.

The servers[0].url in the files is the placeholder https://api.your-brand.com; set your real host in your generator or client.
