Paid Operations (2)

GET /api/v1/payment-discovery dynamic
Payment discovery (402 challenge only).

Returns HTTP 402 with MPP (`WWW-Authenticate: Payment …`) and x402 v2 (`PAYMENT-REQUIRED`) on unpaid requests. No path parameters and no database access — use for tooling that must see a realm challenge before heavy validation. The request body is optional (see schema); omit it or send `{}`. Amount is the static floor ($0.05 USD), not a post purchase.

Parameters

NameInTypeRequiredDescription
Authorization header string No MPP (Payment HTTP Authentication Scheme): after HTTP 402, retry with `Authorization: Payment <credential>`.
PAYMENT-SIGNATURE header string No x402 v2: after HTTP 402, retry with the encoded payment payload from the `PAYMENT-REQUIRED` challenge (same header name as in `@x402/core` HTTP transport).

  "properties": {},
  "type": "object"
}
GET /api/v1/publications/{publicationSlug}/{postSlug} dynamic
Get full post content (paid).

Resolves the post, then returns HTTP 402 until the client pays via MPP and/or x402 on the same response (WWW-Authenticate + PAYMENT-REQUIRED). The challenge amount is the stored per-post price in USD, or at least $0.05 when the post has no source price (see OpenAPI x-payment-info dynamic range; runtime 402 is authoritative).

postSlug path string Yes Post slug from the publication feed.
importer query string No When set to `1`, skips payment and redirects to the app import flow after finding the post.
Authorization header string No MPP (Payment HTTP Authentication Scheme): after HTTP 402, retry with `Authorization: Payment <credential>`.
PAYMENT-SIGNATURE header string No x402 v2: after HTTP 402, retry with the encoded payment payload from the `PAYMENT-REQUIRED` challenge (same header name as in `@x402/core` HTTP transport).
