What it does

Static security scan of a code snippet. Finds hardcoded secrets (AWS keys, private keys, API keys, DB connection strings with passwords), eval/exec, command injection, HTTP calls with no timeout, weak hashes (md5/sha1), bare except and unverified JWT. Returns one entry per finding with rule, severity, exact line number, the offending line and a suggested fix. Rule-based and deterministic: no LLM, so the same snippet always returns the same findings. Send Python or JavaScript as plain text. Not a

Use with an agent

Discover. Agents find this listing with GET https://bazaar.saylorinnovations.com/discovery/search?query=…, the MCP tool search_resources, or /discovery/resources.
Inspect. Fetch /resources/38392.json for the price and payment options.
Pay. Call GET https://fachada.chelsea-hermes.workers.dev/scan/v1/code/scan. The provider answers 402 with its payment requirements. An x402 client signs one of the options below and retries with PAYMENT-SIGNATURE.
Execute. The provider returns 200 with the data. Agent Bazaar is not in the request path and never sees your payment.

For humans

You don't need an account or an API key; you need a wallet holding a small amount of USDC on Base, and an x402-capable client (see the examples below). Call the endpoint unpaid first to see exactly what it asks for.
