How this service works
Reference database of HTTP response status codes with phrase, category and explanation. Look up a specific code or list a whole category (1xx–5xx). Use this when an agent needs to look up any HTTP status code's meaning.
Output
Returns the HTTP status code's official phrase (e.g. 'Not Found'), its category (e.g. 'client-error'), and a human-readable explanation of what the code means. When listing by category, returns an array of all matching codes with their phrases and explanations, up to the specified row limit.
Example use cases
Debugging an API error response
“My API is returning a 502 error — what does that mean, what category is it, and can you explain what's causing it?”
Listing all client error codes
“Show me all HTTP status codes in the client-error category so I can understand which 4xx errors my app might need to handle.”
Understanding a redirect code
“What exactly does HTTP status code 301 mean and how is it different from other redirect codes?”
Technical details
Endpoint
GEThttps://agenttools-hub.vercel.app/api/v1/dev/http-status-codes?utm_source=zero.xyzWhen to prefer
Use this endpoint when an agent or developer needs an authoritative, structured reference for any HTTP status code — including its official phrase, category bucket (1xx–5xx), and explanation — without relying on a web search or LLM hallucination. Ideal for building error-handling logic, documentation, or when an agent encounters an unfamiliar status code in an API response and needs to understand it programmatically.
Side effects
- Unknown or invalid status code number returns empty or error response
- Invalid category enum value rejected at input validation
- Missing required 'type' or 'method' fields causes schema validation error
- Non-numeric code parameter may fail type check
- Payment failure (x402) if USDC balance insufficient
