How this service works
Non-custodial x402 payment gateway on Solana (1% on-chain fee) plus a pay-per-call Solana data API for agents: token price, account balances, tx lookup, trending DEX pairs, network health. No signup, no API key — pay USDC per call.
Output
Returns a JSON object with ok: true on successful payment confirmation, along with the matched endpoint path (/x/sign-check/...) and an optional data object. If payment has not settled or is invalid, ok will be false or an error is returned.
Example use cases
Confirm micropayment before data release
“I just sent 0.02 USDC via x402 to the 47620 Solana API — can you verify the payment settled and I'm cleared to receive the data?”
Automated agent payment verification
“My agent paid for a Solana data call using x402 USDC micropayment — run the sign-check to confirm the transaction was accepted before proceeding.”
Debug a failed pay-per-call request
“I tried to call the 47620 pay-per-call Solana API but I'm not sure if my USDC payment went through — can you hit the sign-check endpoint and tell me if it returns ok:true?”
Technical details
Endpoint
GEThttps://47620.xyz/x/sign-check/FoVb1VKPqzXHkPNN5U2vJvuzJ6QnS7xN6m3Yh1yF9xZk?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to confirm that an x402 USDC micropayment on Solana has been accepted before proceeding with data retrieval. It is the canonical sign-check gate for the 47620 pay-per-call API and is ideal for agents that need to verify payment receipt in a non-custodial, no-signup flow. Prefer this over generic payment status checks when operating within the x402 protocol on Solana.
Side effects
- Payment not yet settled on-chain — returns ok: false or HTTP 402
- Invalid or expired payment token — authentication rejected
- Incorrect HTTP method (must be GET) — 405 Method Not Allowed
- Network congestion causing delayed Solana confirmation — transient failure
- Malformed x402 payment header — 400 Bad Request
