# Delx Rate Limit Parse

> Delx Rate Limit Parse is a paid API for AI agents from api.delx.ai, paid per call via x402, $0.003/call, status unknown (last checked 2026-09-13).

Normalizes common HTTP rate-limit and retry headers into deterministic machine-readable JSON for use in agent 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 delx-rate-limit-parse-4ccffcf2 -d '<json body>'
```

Example prompt: Parse these HTTP response headers for me and extract all the rate-limit and retry info into structured JSON: {'X-RateLimit-Limit': '100', 'X-RateLimit-Remaining': '3', 'X-RateLimit-Reset': '1717200000', 'Retry-After': '30'}

## When to prefer this

Choose this endpoint when your agent needs to programmatically interpret HTTP rate-limit and retry headers in a stateless, deterministic, low-cost preflight step before making downstream API calls or policy decisions. Ideal for enterprise agent workflows where consistent, machine-readable rate-limit data is required without maintaining state or calling a heavier infrastructure service.

## Known failure modes

- Missing or empty headers object returns an error or empty result
- Unrecognized header formats may not be parsed
- Malformed header values (non-numeric where numeric expected) may produce null fields
- Network timeout or service unavailability returns a 5xx error
- Invalid input schema returns a 4xx validation error

## How this service works

Normalize common HTTP rate-limit and retry headers. Use it as a bounded preflight or analysis step inside an enterprise agent workflow before data, policy, integration, security, or commercial decisions reach production. Returns deterministic machine-readable JSON for $0.003 USDC via x402 on Base. Execution is first-party, local-only, stateless, memory-only, and has no paid upstream or input retention. Results are advisory; the caller remains responsible for authorization and production control…

## Output

Returns a deterministic machine-readable JSON object containing normalized rate-limit fields extracted from the supplied HTTP headers, including values such as limit, remaining requests, reset timestamp, and retry-after interval — structured for direct consumption by agent decision logic.
