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 success, plus a data object and the endpoint path. Indicates whether the queried Solana signature/account passes validation.

Example use cases

Verify Solana signer before transaction

“Before I process this transfer, can you verify that the Solana account 9VaAPD1CPE4i8pquaRwE7LvZXMmvGdgffD4Q8xJgaQRu has a valid signature? Just pay the tiny USDC fee per check.”

On-chain auth check for agent workflow

“My agent needs to confirm a Solana wallet signature is valid as part of an automated DeFi workflow — run the sign-check for address 9VaAPD1CPE4i8pquaRwE7LvZXMmvGdgffD4Q8xJgaQRu and tell me if it comes back ok.”

No-signup Solana signature audit

“I don't want to sign up for any service — just do a quick pay-per-call signature validation on the Solana account 9VaAPD1CPE4i8pquaRwE7LvZXMmvGdgffD4Q8xJgaQRu and return whether it's valid.”

When to prefer

Choose this endpoint when you need keyless, no-signup Solana signature or account validation and are willing to pay micro-USDC per call via x402. Ideal for AI agents that need on-chain verification without managing API credentials, especially in automated DeFi or Web3 workflows on Solana.

Side effects

Payment not settled — returns 402 if USDC payment via x402 is not completed
Invalid or unknown account address — may return ok: false or empty data
Network congestion on Solana — delayed response or timeout
Malformed request — missing required input fields returns error
Insufficient USDC balance — payment fails, endpoint not called
