How this service works

200 pay-per-call tools for AI agents, from $0.001 per request in USDC on Base or Solana with x402. No account, no API key.

Output

Returns a JSON object containing the transaction signature, its current status (e.g. 'success'), confirmation_status (e.g. 'finalized', 'confirmed', 'processed'), the slot it was included in, any error (null if successful), and current confirmations count.

Example use cases

Confirm payment received on-chain

“I just sent a Solana payment and got signature 4WgK9w95nm6YFXD3q9uqg8HT7mpcjxmZSWdzGUuses1Dz26LXTF7zzxwWhaTzqViqsyQn24V7qd2SF4yiWpSDhfx — can you check if it's confirmed on-chain yet?”

Debug a failed Solana transaction

“My Solana transaction 5xYt3Kp8zMnQw7VbRcLdAeHjNuFoGs2TiWvXkErOpDqCmBaUlZhYsSfRtJgIyPwNc3Mv1XbAoKdEqFuGzHjTpRs didn't seem to go through — can you look it up and tell me if there was an error?”

Verify NFT mint transaction finality

“I minted an NFT on Solana a few minutes ago with transaction signature 3QrK8mP2nTjXwYzLbVdAfHiNuGoEs1ThWvCkErNpDrCmBaUlZiYtSfRsJgIxPvNc2Mu0WbAoJdFqEuGzHjTpRt — has it finalized?”

When to prefer

Use this endpoint when you need a quick, no-account, pay-per-call lookup of a Solana transaction's status by its signature — ideal for AI agents that need to verify on-chain payment or action confirmation without setting up Solana RPC infrastructure or managing API keys.

Invalid or malformed base58 signature returns an error response
Transaction not yet indexed may return not-found or pending status
