Tools & Capabilities Breakdown

get_pricing
What a delivery costs, which packs exist, and the exact x402 payment requirements for each. Balance is counted in DELIVERIES, not money, and packs never expire. Call this before buying.
get_docs
One section of the machine documentation: quickstart, headers, signature, notice, errors, billing or limits. Omit `section` to get the whole document.
get_service_status
Whether the service is currently selling, on which network, and if not — why not. This is configuration, not liveness: the full health endpoint is at /health.
list_tasks
Your tasks and their state. Needs your management token as an Authorization header on this connection.
get_task
A single task: schedule, destination, state, next run, and how many failures in a row it carries.
