How it works

The Machine Payment Protocol turns the paywall into a single HTTP round-trip. No accounts, no cards, no human in the loop.

  1. 1
    Agent calls endpoint

    GET /api/recipe hits the paywalled resource.

  2. 2
    Server returns 402

    Response includes payment instructions for Tempo + pathUSD.

  3. 3
    Agent pays via Tempo

    Signs a $1.00 transfer. No human approval required.

  4. 4
    Recipe is delivered

    Same endpoint, retried with credential. Markdown comes back.

For agents

Discoverable, machine-readable, idempotent. Wire it up in two minutes.

EndpointGET · 402
GET /api/recipe

Returns 402 Payment Required with a Tempo charge intent for $1.00 pathUSD. Once the credential is attached, the same call returns text/markdown.

curlcopy & run
# 1. Discover the price
curl -i https://yalalag-originals.example.com/api/recipe
# → HTTP/1.1 402 Payment Required
# → WWW-Authenticate: Mppx ...

# 2. Pay $1.00 pathUSD via Tempo, retry with credential
curl https://yalalag-originals.example.com/api/recipe \
  -H "Authorization: Mppx <credential>"
# → 200 OK · text/markdown · the full recipe

Most MPP clients (and any agent framework with the mppx/client SDK) handle the 402 handshake automatically — a single call is all you write.
