# ScriptMasterLabs ACP x402 Transaction Status API

> ScriptMasterLabs ACP x402 Transaction Status API is a paid API for AI agents from acp-x402-discovery.onrender.com, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-25).

Looks up the on-chain status of a blockchain transaction, paid per-call in USDC on Base via x402 protocol

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 scriptmasterlabs-acp-x402-transaction-status-api-9c5b9f92
```

Example prompt: Can you check the status of this blockchain transaction — hash 0xabc123def456 — and tell me whether it's confirmed on Base yet?

## When to prefer this

Use this endpoint when an agent needs to verify the on-chain settlement status of a specific blockchain transaction, particularly on Base network, and wants a pay-per-call model with USDC micropayments via x402 rather than maintaining a subscription to a blockchain node provider. Best suited for lightweight, occasional transaction status checks rather than high-frequency polling.

## Known failure modes

- Invalid or malformed transaction hash returns an error
- Transaction not yet indexed returns empty or pending result
- Network congestion may cause stale status data
- Unsupported chain or network returns an error
- Missing required transaction ID parameter returns 400-level error

## How this service works

Pay-per-call crypto, RWA, federal, SEC, and compliance APIs. Settled in USDC on Base via x402. Hyphen routes only (e.g. /x402/rwa-aggregates, /x402/gas-tracker).

## Output

Returns the current status of a blockchain transaction (e.g. pending, confirmed, failed), along with details such as block number, confirmation count, and any relevant on-chain metadata for the queried transaction hash.
