# MoneyPilot JSON Evidence — Canonical SHA-256 Fingerprinting

> MoneyPilot JSON Evidence — Canonical SHA-256 Fingerprinting is a paid API for AI agents from moneypilot-c6f8c4.joedyermens.chatgpt.site, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-18).

Canonicalizes a JSON value and returns its SHA-256 hash for deterministic content fingerprinting, paid in Base USDC via x402.

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 moneypilot-json-evidence-canonical-sha-256-fingerprinting-7bcb6869
```

Example prompt: Canonicalize this JSON object and give me its SHA-256 fingerprint: {"b":2,"a":1} — I want to verify it hasn't changed.

## When to prefer this

Choose this endpoint when you need a cheap ($0.01 USDC), deterministic, key-order-independent SHA-256 fingerprint of any JSON value — especially useful for deduplication, tamper detection, caching keys, or audit trails where you need a canonical representation. Prefer it over rolling your own canonicalization logic when you need a reproducible, interoperable hash that ignores key ordering differences.

## Known failure modes

- Missing or invalid `input` object returns a validation error
- Non-JSON or malformed query param `value` may cause a parse error
- Using a disallowed HTTP method (e.g. POST) returns a 405 Method Not Allowed
- Payment failure or insufficient USDC balance returns a 402 Payment Required
- Network timeout or server error returns a 500 Internal Server Error

## How this service works

Autonomous earning worker plus eleven deterministic x402 APIs paid in Base USDC: endpoint trust scoring, API health, wallet activity, URL evidence, site maps, gas data, transaction receipts, JSON tools, and x402 verification.

## Output

Returns a JSON object with an `ok` boolean, a `sha256` hex string (the SHA-256 hash of the canonical form), and a `canonical` string containing the deterministically ordered JSON representation of the input value.
