How this service works
Validates an IP address's physical route and latency offsets to verify country compliance, returning a cryptographically signed Geolocation Certificate. Matches: geolocate ip check, secure location verification, ip route validator, compliant network geodata.
Output
A JSON object containing the queried IP, a VERIFIED or FAILED status, the actual detected country code, the expected country code, a unique certificate ID, a signed cryptographic proof string attesting to the location check result, and a confidence level (high/medium/low).
Example use cases
Example prompt
“Can you verify that the IP address 8.8.8.8 is actually located in the United States and give me a signed proof certificate I can use to confirm it?”
Technical details
Endpoint
POSThttps://statepulse-api.hahavoid0.workers.dev/location/verify-presenceWhen to prefer
Choose this endpoint when you need a cryptographically signed, verifiable attestation that an IP address corresponds to a specific country — not just a raw geolocation lookup. Ideal for compliance workflows, access control enforcement, or audit trails where a machine-readable proof certificate is required alongside the geolocation result.
Side effects
- IP address not routable or invalid format — returns error or unsupported:true with no result
- Country mismatch — status is not VERIFIED, actual_country differs from expected_country
- Payment failure — x402 USDC payment on Base rejected or insufficient
- Service unavailable — Cloudflare Worker timeout or cold start failure
- Unknown IP geolocation — confidence returned as low with uncertain result
