Flat API client for Python

Official client for the Flat REST API, generated from Flat's public OpenAPI specification and kept current automatically.

pip install flat-api

from flat_api import FlatClient

client = FlatClient(access_token="YOUR_TOKEN")
me = client.api_client  # generated APIs hang off here

Get a token in seconds with a Personal Access Token; it works exactly like an OAuth access token for your own account.

What this client does for you

• Typed errors. Branch on the error, not the status code. Flat returns HTTP 403 for both rate limiting and authorization failures, so status alone cannot tell them apart.
• Automatic retries. Rate limits and server errors are retried with backoff. Flat sends no Retry-After, so the client reads X-RateLimit-Reset instead.
• Automatic pagination. Eight collection endpoints are cursor-paginated with the cursor in a Link header. You get an iterator; you never touch a cursor.
• OAuth2 built in. Authorization URLs, code exchange and transparent token refresh.
• Full type information, so your editor and your coding assistant both know the API.

Pagination

from flat_api import paginate

for score in paginate(api.get_user_scores_with_http_info, user="me"):
    print(score.title)

Errors

from flat_api import FlatRateLimitError, FlatNotFoundError

try:
    ...
except FlatRateLimitError as exc:
    print("retry after", exc.reset)
except FlatNotFoundError:
    print("no such score")

Asynchronous use

client = AsyncFlatClient(access_token="YOUR_TOKEN")
# every operation is awaitable\n```

## Verifying this package

Every release carries a signed provenance attestation linking the package back to the commit, the
workflow run that built it, and the API specification version it was generated from.

```sh
pip download --no-deps flat-api
gh attestation verify flat_api-*.whl --repo FlatIO/api-client-python

Published through PyPI trusted publishing: no long-lived token exists that could publish under this name.

How this client is maintained

Generated from the public specification published at FlatIO/api-reference. A new specification release regenerates, validates and publishes this package automatically, so it never drifts from the API.

Files under docs/reference/ and the client sources are generated: edit the generator configuration in tools/, not the output.
