What an agent reads when it fetches this URL: the whole manifest, in order, with the offer on the last line as a 402 it can pay. Nothing here is a button — an agent does not click, it signs. The page a person reads is here.

Readme

openapi-breaking-change-detector

Detects backwards-incompatible breaking changes between two OpenAPI 3.0/3.1 specifications in CI under 5 seconds.

What Can Break?

Removed endpoints, dropped HTTP methods, new required parameters, and deleted 2xx response codes that break frontend and mobile API clients.

What Does This Tool Check?

Paths, HTTP verbs, path/query/header parameters, requestBody schema mutations, and response status codes.

What Does It NOT Check?

Runtime server latency, backend business logic correctness, or network firewalls.

How Fast Can I Run It?

Under 5 seconds. Zero external dependencies. Pure Node.js standard library.

# Clone and run
git clone git@github.com:genesiscode2026/openapi-breaking-change-detector.git
cd openapi-breaking-change-detector

# Execute 60-second demo
./bin/openapi-break-detect.js --help
./bin/openapi-break-detect.js --old examples/v1.json --new examples/v2.json

What Do I Get?

Deterministic CLI Exit Codes: Returns code 0 on backward-compatible contracts; returns code 1 on breaking drift.
Machine-Readable JSON: Pass --json to integrate directly into GitHub Actions, GitLab CI, or pre-commit hooks.
Human-Readable Diffs: Clear, actionable error reports with exact field pointers.

The resource endpoint answers 402 with the price and the exact bytes to sign; the same request carrying PAYMENT-SIGNATURE returns a signed download URL. Access is granted only after settlement returns a transaction hash. A person can do the same thing with a browser wallet on the product page.

# the 402, with the price and the exact bytes to sign
curl -si https://x402git.com/api/r/genesiscode2026/openapi-breaking-change-detector

# what your wallet already owns, and what the next fetch would cost it
curl -s https://x402git.com/api/v/genesiscode2026/openapi-breaking-change-detector \
  -H "X-Wallet-Signature: 0xYOURADDRESS.<nonce>.<signature>"

The first request answers this — a real quote, made for this page load:

HTTP/1.1 402 Payment Required
