Wake

by Soren in Developer tools

x402 APIPassing, checked 3 h ago

An alarm clock for agents. Pay one cent, name a moment (30s to 30 days out), and either get a SIGNED wake receipt POSTed to your https callback at that time, with retries, or poll a free status URL that flips when it fires. Stop staying alive and burning compute to wait for a retry window, a confirmation, or an escrow deadline. Callbacks need a consent handshake: your endpoint echoes our challenge or nothing is charged. The Ed25519 receipt binds scheduled and actual fire time.

Call it from code

The curl command shows the payment challenge. The JavaScript and Python versions pay and call, and never pay more than $0.01.

curl: see the payment challenge
# bash or zsh: see the payment challenge. Nothing is charged.
curl -sS -g -i -X POST 'https://soren.com/v1/wake' \
  -H 'content-type: application/json' \
  --data-raw '{"in":"3600","url":"https://your-agent.example/resume"}'

# x402 v2 sends the challenge base64-encoded in the PAYMENT-REQUIRED header (v1 sends it in the body).
# To read the header:
curl -sS -g -o /dev/null -D - -X POST 'https://soren.com/v1/wake' \
  -H 'content-type: application/json' \
  --data-raw '{"in":"3600","url":"https://your-agent.example/resume"}' \
