How this service works
Confirmation status of a Solana transaction signature: found, slot, processed/confirmed/finalized, success or error (searches history). Poll this after sending a tx.
Output
Returns a JSON object with the transaction signature, a boolean 'found' field, the slot number it landed in, its confirmation level (processed, confirmed, or finalized), and whether it succeeded or resulted in an error.
Example use cases
Confirm payment after token transfer
“I just sent a SOL payment and got back this signature: 5KtPn1LGuxhFiwjxErkxTb3JyZJvZ1a8K9bZ7bHmDy6rH3Xe4uUyvBkpQeA5mZtD9qLsuGhK4r2yXkPqBYhNfP2 — can you check if it's been confirmed or finalized yet?”
Debug a failed Solana transaction
“My Solana transaction with signature 3FPgxQGWb9kYpHv7QZC8R2N1XoTmVzHkWsAeP6LmD4uJ9bEfRyNsMcK1tZBvXqUi5nLjWD8a3rYoEcBmTkGhFN1 didn't seem to work — can you look it up and tell me whether it succeeded or errored out, and which slot it landed in?”
Poll transaction after DeFi swap
“I just submitted a swap on Solana — here's the signature: 2hJmK8vRnP3xGdBqWtZ5LcSoFkYeH7mNwUjXiPbTvA1sDqEgRyLfCuMnKzOaWpVi4rBeZ9JxHoNmEdFgTkP3Qs — please keep checking until it shows as confirmed or finalized.”
Technical details
Endpoint
GEThttps://mintintel.35-171-220-195.sslip.io/v1/sol/sig-status/:sig?utm_source=zero.xyzWhen to prefer
Use this endpoint immediately after sending a Solana transaction to poll for its confirmation status. It is ideal for agentic workflows that need to wait for finality before proceeding, detect on-chain errors, or verify that a payment or swap landed successfully. Prefer this over generic block explorers when you need a machine-readable, low-latency status response programmatically.
Side effects
- Signature not found in recent history — returns found: false if the transaction is too old or was never broadcast
- Invalid base58 signature format causes a 400 error
- Signature found but transaction execution failed — error status returned in the response
- RPC node lag may delay status update immediately after submission
- Payment required (402) if x402 micropayment header is missing or invalid
