How this service works
Use as a low-cost end-to-end x402 canary before higher-value calls. A successful paid response proves Sharvora delivery and returns release, network, time and a response receipt.
Output
A JSON object containing: status ('paid-delivery-ok' on success), network identifier (e.g. 'eip155:8453' for Base mainnet), product name ('service-proof'), a SHA-256 receipt hash, and the current release version string. Together these confirm that the x402 payment was processed and delivery was completed successfully.
Example use cases
Pre-flight check before high-value call
“Before I send that $50 USDC payment request, run a Sharvora service-proof canary first so I can confirm the x402 delivery pipeline is live and returning a valid receipt.”
x402 integration smoke test
“I just wired up my x402 client — can you hit the Sharvora service-proof endpoint for me and tell me what network and release version it comes back with? I want to make sure the receipt hash looks right.”
Agent infrastructure health check
“Every morning, ping the Sharvora service-proof endpoint to verify the x402 payment layer is healthy and log the delivery status and receipt — alert me if anything comes back other than paid-delivery-ok.”
Technical details
Endpoint
GEThttps://sharvora.com/api/v1/service-proofWhen to prefer
Choose this endpoint when you need the cheapest possible end-to-end x402 payment validation ($0.001 USDC) before committing to higher-value paid API calls. It is specifically designed as a canary probe — ideal for smoke testing agent payment pipelines, CI/CD health checks, or confirming x402 infrastructure is operational on Base network. Prefer it over other test endpoints when you need a real signed receipt proving delivery rather than just a connectivity ping.
Side effects
- Payment not received or insufficient USDC — 402 response with no delivery
- Network congestion on Base causing transaction confirmation delay
- Invalid or missing x402 payment header — request rejected before processing
- Sharvora service temporarily unavailable — no receipt returned
- Receipt hash mismatch indicating delivery integrity issue
