Example use cases
Onboarding brief for new agent integration
“I'm setting up a new AI agent that calls a JSON-based POST API. Can you fetch the integration brief for it using x402 and USDC on Base so I know exactly how to wire it up?”
Audit drift before deploying agent update
“Before I push a new version of my agentic workflow, can you pull an integration brief via the x402 seller so I have the latest spec and can catch any drift from my current setup?”
Documenting a client's SaaS agent integration
“I need to produce an integration brief document for my client's POST-based SaaS integration — go ahead and pay the $0.25 via x402 USDC on Base and return the full brief.”
Technical details
Endpoint
POSThttps://x402-seller-mainnet.wansolek.workers.dev/v1/briefWhen to prefer
Choose this endpoint when you need a structured, paid integration brief for an HTTP-based agentic SaaS service and are operating within the x402 micropayment ecosystem on Base (USDC). It is ideal for AI agents that need authoritative integration documentation on demand without requiring traditional API key provisioning. Prefer this over free manifest ($0.01) or drift audit ($0.05) endpoints when you need the full integration specification rather than a summary or audit.
