# Explorer Gateway API — Solana Transaction Instructions

> Explorer Gateway API — Solana Transaction Instructions is a paid API for AI agents from api.blockchain.com, paid per call via x402, $0.0015/call, status unknown (last checked 2026-10-01).

Fetches the decoded instruction details of a specific Solana transaction by transaction ID

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-3cd6daff -d '<json body>'
```

Example prompt: Can you pull the decoded instructions for this Solana transaction — txId 5Y2Qv8...abc123 on the SOL network — and tell me what programs and accounts were involved?

## When to prefer this

Choose this endpoint when you need to inspect the specific program instructions executed within a Solana transaction — such as auditing DeFi interactions, verifying NFT operations, or debugging on-chain program calls. It is ideal when you already have a transaction signature and need instruction-level detail rather than just high-level transfer metadata.

## Known failure modes

- Invalid or malformed txId returns an error response
- Transaction not found on the Solana network returns a 404 or empty result
- Unsupported network value causes a validation error
- Rate limiting or payment failure (x402) blocks the request
- Network identifier mismatch (e.g. wrong chain for the txId format)
