## Paid route (x402 v2)

GET https://x402.rendraputra.dev/screen?token=<contract|mint>&chain=<solana|base|ethereum|bsc|polygon|arbitrum>

- Unpaid, it answers HTTP 402 with the canonical challenge in the PAYMENT-REQUIRED header
  (also in the body) and `accepts[0]["amount"]` = 100000 for one token, 250000 for a
  2-5 token batch (6-decimal USDC).
- Pay on Base, then retry the same URL with `PAYMENT-SIGNATURE: <base64 PaymentPayload v2>`.
- Settlement is fail-closed: the report is generated only after the facilitator settles;
  a failed settle returns 402 with the facilitator's reason, never a free report.
- Success returns 200 text/markdown plus the settlement receipt in PAYMENT-RESPONSE.

## MCP route (streamable HTTP)

POST https://x402.rendraputra.dev/mcp — JSON-RPC 2.0 (initialize, tools/list, tools/call) exposing one
tool, `token_risk_screen` {token, chain}. Same product, same price. An unpaid tools/call
returns HTTP 402 with the same canonical challenge; pay and retry with the payment under
`params._meta["x402/payment"]` (or a PAYMENT-SIGNATURE header).

## Free routes

- GET https://x402.rendraputra.dev/healthz — liveness + price + accepted networks.
- GET https://x402.rendraputra.dev/openapi.json — OpenAPI 3.1 contract (x-payment-info: x402, $0.1 single / $0.25 batch).
- GET https://x402.rendraputra.dev/.well-known/x402 — machine-readable offer (discovery shape).
