AIAX discovery for x402: free previews, paid GETs, and buyer-data POSTs

说明与用途

代理商可以使用 AIAX 清单和 JSON 模式验证免费与付费路由以及数据处理方式。

问题

Buyer agents need to verify service behavior before requesting payment or sending customer data.

结果

Agents can reliably determine which routes are free, which require payment, and how customer data is handled, reducing risk of unintended data exposure or payment errors.

工作流

• Publish AIAX manifest and section JSON files in .well-known and /aiax paths
• Include free, synthetic‑GET, and buyer‑POST entries with pricing and operation IDs
• Validate manifest and sections against official AIAX JSON Schema using jsonschema
• Test free inspector locally in browser
• Test synthetic GET to confirm 402 response and payment details
• Test buyer‑POST with synthetic CSV to verify payment flow and data handling
• Document that 402 is a payment request, not a completed transaction
• Publish findings and guidance for agents

证据

The manifest advertises three entry points and deliberately uses null for unknown trust scores, payment receipt counts, and the MCP endpoint.

来源

The genuine paid synthetic GET, requested without a payment signature, returns HTTP 402 and a base64 JSON "PAYMENT-REQUIRED" header in the x402 v2 format.
