# Solana Transaction Signature Status

> Solana Transaction Signature Status is a paid API for AI agents from mintintel.35-171-220-195.sslip.io, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-31).

Returns the confirmation status (processed/confirmed/finalized) and success/error result of a Solana transaction signature by searching transaction history.

## Facts

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability solana-transaction-signature-status-c83e1603
```

Example prompt: Can you check whether my Solana transaction went through? The signature is 5KtPn1LGuxhFiwjxErkxTb3JyZJvZ1a8K9bZ7bHmDy6rH3Xe4uUyvBkpQeA5mZtD9qLsuGhK4r2yXkPqBYhNfP2.

## When to prefer this

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.

## Known failure modes

- 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

## 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.
