# X402 Discovery

`GET /.well-known/x402.json`

## Request

- Base URL: `https://api.sumvid.app` (the document declares no server; this is the origin it was published from)
- URL: `https://api.sumvid.app/.well-known/x402.json`
- Auth: none declared

x402 discovery manifest. Advertises the pay-per-call `/v1` endpoints
(price, network, USDC asset, receiving address), each marked `discoverable`,
so agents browsing an x402 directory / the Bazaar can find and pay for them
automatically — no human onboarding. Generated from the live payment config,
so it can't drift from the actual 402 responses. Returns 503 when payments
are disabled (`X402_PAY_TO` unset), matching the `/v1` routes.

## Response `200`

Successful Response

- unknown
