# Explorer Gateway API – Solana Transaction Instructions

> Explorer Gateway API – Solana Transaction Instructions is a paid API for AI agents from api.blockchain.info, paid per call via x402, $0.0015/call, status unknown (last checked 2026-10-02).

Retrieves the decoded instructions from a specific Solana transaction by transaction ID via the blockchain.info explorer gateway

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 explorer-gateway-api-solana-transaction-instructions-2a5f73ac -d '<json body>'
```

Example prompt: Can you pull the decoded instructions for this Solana transaction — txId 5KtP9x...abc on the SOL network — and tell me what programs were called and what each instruction did?

## When to prefer this

Choose this endpoint when you need detailed, decoded instruction-level data for a specific Solana transaction — particularly when debugging smart contract interactions, auditing DeFi operations, or tracing on-chain program calls. It is backed by the Blockchain.com explorer infrastructure, which provides reliable multi-chain data. Prefer this over raw RPC calls when you want a structured JSON response from a hosted, paid endpoint without managing your own Solana node.

## Known failure modes

- Invalid or malformed txId returns an error response
- Transaction not found on the network returns 404 or empty result
- Incorrect network value (non-SOL) may return misrouted or empty response
- Payment failure (x402 protocol) blocks the request if USDC payment is not processed
- Rate limiting or network timeouts may cause transient failures
- Very recent transactions may not yet be indexed and return no result
