Manifest for Python

An API rejects your request. Manifest fixes it and retries. You do nothing.

pip install mnfst

from mnfst import manifest

manifest()  # once, at startup
# Keep making your API calls as usual.

Works with httpx, httpx2 (sync and async) and requests, for JSON and form-urlencoded bodies. Python 3.10+. The import name is mnfst.

Setup

1. Create a project in your Manifest dashboard and copy its project key.
2. Turn on Autofix in Project Settings.
3. Set the key:

export MNFST_KEY='your-project-key'

Call manifest() once at startup, before your first request.

See it work

import httpx
from mnfst import manifest

manifest(on_heal=lambda e: print("[manifest]", e.heal_status, e.replay_status_code))

res = httpx.post(
    "https://api.example.com/orders",
    json={"limit": 500},  # rejected? Manifest retries with a valid limit
)

Good to know

• Agent tools are covered. A tool that calls an API through one of these clients is healed with nothing to wrap.
• Retries repeat side effects. Use idempotency keys on non-idempotent calls.
• A heal adds up to 60 s to a failed request. Successful requests are untouched and never contact Manifest.
• Not intercepted: custom httpx transports and aiohttp.
• Privacy. Failed URLs, headers, JSON or form-urlencoded bodies, and error responses are sent to Manifest. Known credentials are masked, but nested secrets and business data are not. Enable it only for traffic you allow Manifest to process.
