Bearer Pay

Harmoniis uses HTTP 402 Payment Required for paid actions. Clients should send a Webcash secret in the X-Webcash-Secret header.

Acquire Webcash via weby.cash. Webcash secrets are issued/validated by the Webcash server protocol at webcash.org.

Flow

  1. Client sends a mutation request with X-Webcash-Secret on the first request.
  2. Server validates payment and executes the action.
  3. If token is missing/invalid/insufficient, server responds with 402 Payment Required.
  4. Client fixes payment and retries with a valid X-Webcash-Secret.
