# Quartermaster Base Transaction Status Checker

> Quartermaster Base Transaction Status Checker is a paid API for AI agents from quartermaster.surewhynot.app, paid per call via x402, $0.002/call, status unknown (last checked 2026-09-14).

Checks the status of a Base blockchain transaction by hash, returning success/reverted/pending state, confirmation count, gas used, and an explorer link.

## Facts

- Endpoint: GET https://quartermaster.surewhynot.app/v1/tx
- Price: $0.002/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-14
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/quartermaster-base-transaction-status-checker-f25ca23f

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 quartermaster-base-transaction-status-checker-f25ca23f
```

Example prompt: Can you check whether this Base transaction went through successfully: 0x3a1b2c4d5e6f7a8b9c0d1e2f3a4b5c6d7e8f9a0b1c2d3e4f5a6b7c8d9e0f1a2b — tell me if it succeeded or reverted and how many confirmations it has?

## When to prefer this

Use this endpoint when you need to verify the outcome of a specific Base transaction by hash — especially in x402 payment flows where you need to confirm settlement before proceeding. Prefer over full settlement-audit endpoints when you only need basic status, confirmations, and gas info without USDC transfer decoding or payment field matching.

## Known failure modes

- Invalid hash format (not a 64-char 0x hex string) → validation error
- Transaction hash not found on Base → not found error
- Node/RPC unavailability → upstream timeout
- Hash belongs to a different chain → incorrect or missing result

## How this service works

Check the status of a Base transaction: success/reverted/pending, confirmations, gas used, and explorer link — settlement verification for agents and payment flows.

## Output

Returns the transaction status (success, reverted, or pending), number of confirmations, gas used, and a block explorer URL for the given Base transaction hash.
