# Quartermaster Transaction Receipt

> Quartermaster Transaction Receipt is a paid API for AI agents from quartermaster.surewhynot.app, paid per call via x402, $0.002/call, status unknown (last checked 2026-09-13).

Returns a formatted settlement receipt for a Base transaction, including timestamp, status, decoded token transfers, and explorer link — optimized for x402 payment records.

## 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 quartermaster-transaction-receipt-855f132a
```

Example prompt: Can you pull up the receipt for Base transaction 0x3a1f2c9d8e4b07560af1234567890abcdef1234567890abcdef1234567890ab12 — I need the timestamp, status, decoded token transfers, and explorer link.

## When to prefer this

Use this endpoint when you need a human-readable, structured receipt for a specific Base transaction — especially for x402 payment audit trails. Prefer this over raw RPC calls when you need decoded token transfers and a formatted summary rather than raw blockchain data. Choose over the x402 settlement verifier when you need a presentable record rather than just a pass/fail confirmation.

## Known failure modes

- Invalid or malformed transaction hash (not matching ^0x[0-9a-fA-F]{64}$) returns a validation error
- Transaction hash not found on Base network returns a not-found error
- Network timeout or RPC unavailability may return a 5xx error
- Transaction exists but has no token transfer events may return a receipt with empty transfers array

## How this service works

Formatted settlement receipt for any Base transaction hash or Solana signature: timestamp, status, decoded token transfers, explorer link — records for x402 payments on either rail.

## Output

A formatted settlement receipt including the transaction timestamp, confirmation status, decoded token transfer details (e.g. USDC amounts and addresses), and a block explorer link for the given Base transaction hash.
