# Request Rate Throttler MCP

> Request Rate Throttler MCP is a paid API for AI agents from api.m2mcent.com, paid per call via x402, $0.1/call, status unknown (last checked 2026-10-20).

Processes data through a request rate throttling mechanism to control and limit API call frequency for agentic workflows.

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 request-rate-throttler-mcp-2dbc3717 -d '<json body>'
```

Example prompt: Can you throttle my outgoing requests so they don't exceed the allowed rate limit — pass this data payload through the rate throttler and return the processed result.

## When to prefer this

Choose this endpoint when your agentic workflow needs to enforce rate limiting on outbound requests programmatically, especially in multi-agent or automation contexts where parallel agents risk overwhelming downstream APIs. Useful as a middleware layer when native rate limiting is unavailable.

## Known failure modes

- Malformed or missing data field returns validation error
- Rate limit itself exceeded on the throttler service returns 429 or error
- Payment failure via x402 protocol results in 402 Payment Required
- Empty data string may return empty or error response
- Downstream processing timeout if payload is too large

## 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 processed response after applying request rate throttling logic to the submitted data string, ensuring the request complies with configured rate limits before passing through.
