How this service works
Synthex Forge x402 Receive: 41 paid verification, attestation and governance endpoints (Ed25519 + SHA-256 signed artifacts) plus free verify/public-key/standard sibling routes. Paid routes answer HTTP 402 with an x402 v2 `payment-required` envelope (atomic USDC on Base mainnet, chain ID 8453). Free routes are declared with `security: []` per the x402scan discovery spec.
Output
Returns a JSON object with an 'ok' boolean indicating whether the service passed the uptime/availability verification, along with a cryptographically signed attestation artifact using Ed25519 + SHA-256, suitable for governance, compliance, or audit purposes.
Example use cases
SLA compliance attestation for auditors
“Run an uptime verification check on https://api.paymentprocessor.io and get me a signed attestation I can hand to our compliance team — include the settlement transaction 0xdeadbeef1234 as proof of payment.”
Governance proof for decentralized protocol
“I need a tamper-proof, Ed25519-signed uptime certificate for https://rpc.myprotocol.xyz so our DAO can verify we met last month's availability requirements — last confirmed settlement tx is 0xfeed5678.”
Continuous availability monitoring with signed receipts
“Verify that https://staging.myapp.com is currently up and give me a signed verification artifact I can store — run the standard availability checks and use settlement tx 0xcafe9012.”

Endpoint
POSThttps://x402.synthexforge.com/v1/mcp/verify/uptime?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a cryptographically signed, blockchain-payment-backed attestation of service uptime — not just a simple ping or health check. Ideal for compliance, governance, or audit scenarios where tamper-evident proof of availability is required and you can pay $0.25 USDC per verification on Base mainnet.
Side effects
- Payment not received or x402 payment envelope invalid — returns HTTP 402 with payment-required details
- Service URL is unreachable or malformed — verification may return ok: false
- Invalid or missing last_confirmed_settlement_tx — may reject or fail attestation linkage
- Checks array malformed or unsupported check types — validation error
- Underlying network issues prevent reaching the target service URL
