# M201: Per-user rate limit exceeded

> Manifest error M201 fires when one user sends more than 200 requests per minute. Returns HTTP 429. Fix: back off, retry, or raise the cap on self-hosted.

## What you saw

```text theme={"theme":{"light":"github-light","dark":"github-dark"}}
[🦚 Manifest M201] Too many requests — wait a few seconds and retry.
See https://manifest.build/docs/errors/M201
```

The HTTP status is `429`, so SDKs that respect retry-after will back off on their own.

## Why it happened

Manifest caps each user at 200 requests per minute by default. The cap is there mostly to keep runaway loops from melting the proxy. Your agent crossed it inside a 60-second window.

## How to fix it

1. Add a small delay or exponential backoff on retry. Most SDKs handle this automatically when they see a `429`.
2. If parallel workers are hitting Manifest, throttle them so they share the budget.
3. On a self-hosted install where you need more headroom, raise `RATE_MAX_REQUESTS` in `proxy-rate-limiter.ts`.
