Provable Record / State Auditor — /audit (/structure)

A minimum-viable x402-paywalled endpoint. A client agent POSTs a target identifier (parcel ID, permit application number, or smart-contract address); the server fetches the underlying record, normalizes it, stamps it with a SHA-256 integrity hash, and — once a micro-payment settles — hands back clean JSON.

Setup

python -m venv .venv && source .venv/bin/activate
pip install -r requirements.txt
cp .env.example .env   # fill in X402_PAY_TO_ADDRESS at minimum

Run

uvicorn app:app --reload --port 8402

Test

curl -i -X POST localhost:8402/audit \
  -H "Content-Type: application/json" \
  -d '{"target": "032-114-0090"}'
# -> 402 challenge

curl -i -X POST localhost:8402/audit \
  -H "Content-Type: application/json" \
  -H "X-PAYMENT: any-nonempty-blob-in-mock-mode" \
  -d '{"target": "032-114-0090"}'
# -> 200 structured, hash-stamped record
