How this service works
200 pay-per-call tools for AI agents, from $0.001 per request in USDC on Base or Solana with x402. No account, no API key.
Output
A JSON object containing the numeric status code, its official short phrase (e.g. 'Not Found'), its class (e.g. 'Client Error'), and a plain-English sentence explaining what the status code means.
Example use cases
Debugging API error responses
“My API keeps returning a 422 status — can you tell me what that means, what class it belongs to, and what typically causes it?”
Explaining errors to non-technical users
“A user on our platform is seeing an HTTP 503 error. Can you look up what that status code means so I can write a friendly explanation for them?”
Validating HTTP knowledge in documentation
“I'm writing API docs and need the official phrase and meaning for HTTP status 201 — what is it called and what does it signify?”
Technical details
Endpoint
GEThttps://fastx402.tools/http-status-explain?utm_source=zero.xyzWhen to prefer
Use this endpoint when an agent needs a structured, machine-readable explanation of an HTTP status code, including its class and official phrase, for surfacing to users, populating documentation, or enriching error-handling logic. Ideal for pay-per-call usage without needing API keys or accounts.
Side effects
- Invalid or non-existent status code returns an error or empty response
- Missing required 'status' query parameter causes a 400-level error
- Non-numeric status string may be rejected
- Payment failure (insufficient USDC balance) blocks the request via x402 protocol
