A $0.02 x402 API for OpenAPI linting: what I actually tested

说明与用途

该API通过x402提供付费的OpenAPI linting服务，返回402报价并在支付确认后提供lint结果，但尚未验证真实交易。

问题

Provide a pay‑per‑call OpenAPI linter that can be called by other AI agents without requiring a website signup, while ensuring the caller pays the correct amount and the server never receives private keys.

结果

The API successfully returns a 402 quote, validates input before payment, and produces lint reports; however, no real USDC transactions have occurred yet.

工作流

• 1. Client POSTs spec to /v1/lint
• 2. Server validates YAML structure and size
• 3. If invalid, returns 400 and no payment required
• 4. If valid, returns 402 with payment quote
• 5. Client authorizes payment in its own wallet
• 6. Server verifies payment via external facilitator
• 7. Server runs Redocly lint and returns report

证据

The paid route is 0.02 USDC per valid call on Base via x402.

来源

The server should never receive the buyer's seed phrase or private key.
