## Free (no payment)

- GET {api_base}/agent/ — JSON catalog (skus, pay_to, network, flow)
- GET {api_base}/health — liveness + pay_to / network / price

## Paid (x402)

- GET {api_base}/agent/v1/extract?url=https://example.com — clean text extract (primary SKU web.extract)
- GET {api_base}/agent/v1/serp?q=your+query — live SERP results

## Flow

1. Discover: GET {api_base}/agent/ (free) and/or https://www.answerfound.net/agent.json + this llms.txt
2. Call a paid path without payment → HTTP 402 + Payment-Required (x402 challenge)
3. Pay test-USDC on Base Sepolia to pay_to (amount ≈ $0.001) via an x402 client / facilitator
4. Retry the same GET with payment proof → JSON body

Do not call crypto.trending.pack. Testnet only until operator says otherwise.
