Solana transaction lookup: status, fee and signers

$0.01 per call · failed calls are never charged · no account or API key needed

Look up a Solana transaction by signature, live from mainnet: success or the error, slot and block time, fee in SOL, compute units used, signers, the programs it called and SOL balance changes per account. Use to confirm a Solana payment landed or see what a transaction did. A signature that is not base58 is 400; an unknown or too old signature is 404, both uncharged.

Request

Over HTTP, with a card key from /credits:

curl -H "Authorization: Bearer adt_…" "https://agent-data-tools.revmesh2074.workers.dev/solana/tx?signature=3vsCBRhEzKZ5gkQ59x9qkzVFddwVNFtz5HUW7G1JvMqEaYABtJH1Parn84FAUF2dct2viSXHVVDDRKSbytSSdMU"

Or one of your 25 free calls, no key:

curl "https://agent-data-tools.revmesh2074.workers.dev/solana/tx?signature=3vsCBRhEzKZ5gkQ59x9qkzVFddwVNFtz5HUW7G1JvMqEaYABtJH1Parn84FAUF2dct2viSXHVVDDRKSbytSSdMU&trial=1"

Without a key, the same URL answers 402 Payment Required with x402 and MPP terms, so an agent with a wallet pays per call in USDC (Base, Polygon, Arbitrum or Solana over x402; Base or Tempo over MPP) and retries.
