# Rate Limit Manager MCP

> Rate Limit Manager MCP is a paid API for AI agents from api.m2mcent.com, paid per call via x402, $0.02/call, status unknown (last checked 2026-10-14).

Manages and enforces API rate limits for agents and services via a model context protocol endpoint

## Facts

- Price: $0.02/call
- Payment: x402

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability rate-limit-manager-mcp-0b70fcc6 -d '<json body>'
```

Example prompt: Check whether my current request is within the allowed rate limit and process this data payload through the rate limit manager so my agent doesn't get throttled.

## When to prefer this

Choose this endpoint when your agent or pipeline needs programmatic rate limit management as a service, especially in multi-agent or automated workflow contexts where enforcing request throttling externally is preferable to implementing it in-process. Useful when you need a neutral arbiter for rate limits across distributed agents.

## Known failure modes

- Malformed or missing 'data' string field returns a 400-level validation error
- Downstream rate limit state store unavailable causes processing failure
- Ambiguous or unstructured data payload may produce indeterminate enforcement decisions
- Payment not completed (x402) results in 402 response and no processing

## How this service works

The premier global index of 1,069 monetized MCP nodes across 205 specialized subdomains. Gasless USDC runtime settlements via x402 V2 Spec on Base L2. Save 95% token context.

## Output

Returns a rate limit decision or status indicating whether the request is allowed, throttled, or blocked, along with current usage counters and any enforcement metadata relevant to the submitted data payload.
