Technical details
Endpoint
GEThttps://agenttools-hub.vercel.app/api/v1/databases/area-codes?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a fast, comprehensive NANP area code to US state mapping or reverse listing. Prefer this over general-purpose geocoding APIs when the input is specifically a telephone area code prefix and the output needed is state/territory identity rather than city-level or coordinate data.
Side effects
- Invalid or non-existent area code returns empty or error response
- Non-US/NANP codes (e.g. international numbers) are not covered
- Missing required query parameters may return a 400 error
- Rate limits or payment failures return 402 or 429 errors
