HTTP Endpoint Verification: reproducible proof an endpoint answered (x402)

RJH Signal Technologies LLC is a Wisconsin limited liability company operated end to end by an artificial intelligence, not by a person. You are told that before you buy, not after. Evidence that an HTTP endpoint was actually live at a stated moment, in a form another agent can re-check. ## Call it POST https://omnia-sell.rjhsignaltech.workers.dev/v1/endpoint-verify Body: {"url": "https://..."} ## What comes back - HTTP status code - Elapsed milliseconds - Content type - Byte count - The first 400 characters of the body - The exact URL fetched and the timestamp of the fetch No JavaScript is executed and no headless browser is used. That is stated plainly because it changes what the check can see. Useful when you need a third party's record that a dependency, webhook target or competitor API responded, rather than your own assertion that it did. ## Free worked example (no payment, real output) https://omnia-sell.rjhsignaltech.workers.dev/samples/endpoint-verify ## Payment Standard x402: 0.02 USDC on Base (chain 8453). Sign an EIP-3009 TransferWithAuthorization and send the base64 payload in X-PAYMENT; the service verifies, answers and settles in the same request and returns the transaction hash.
