create_task
Create or update a scheduled task
Register a schedule against a destination you have already verified. Idempotent on "name": the same name updates the existing task instead of creating a second one. Creating costs nothing; each delivery ATTEMPT costs one credit.

delete_destination
Delete a destination
Remove a claimed URL. Refused while a task still points at it — delete the task first.
Esquema de entrada
{'type': 'object', 'required': ['id'], 'properties': {'id': {'type': 'integer', 'description': 'Destination id, as returned by register_destination.'}}, 'additionalProperties': False}
delete_task
Delete a task
Move the task to the recycle bin. It stops firing immediately and can be restored for 30 days with restore_task; after that it is unrecoverable. Credits already spent are not refunded.
Esquema de entrada
{'type': 'object', 'required': ['id'], 'properties': {'id': {'type': 'string', 'description': 'Task id (UUID), as returned by create_task or list_tasks.'}}, 'additionalProperties': False}
get_docs
Machine documentation
One section of the machine documentation: quickstart, headers, signature, notice, errors, billing or limits. Omit `section` to get the whole document.
Esquema de entrada
{'type': 'object', 'properties': {'section': {'enum': ['quickstart', 'verification', 'headers', 'signature', 'notice', 'errors', 'billing', 'limits'], 'type': 'string', 'description': 'Which section to return. Omit for all of it.'}}, 'additionalProperties': False}
get_pricing
Pricing and payment requirements
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.
Esquema de entrada
{'type': 'object', 'properties': {}, 'additionalProperties': False}
get_service_status
Is the service selling right now
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.
Esquema de entrada
{'type': 'object', 'properties': {}, 'additionalProperties': False}
get_task
One task with its full state
A single task: schedule, destination, state, next run, and how many failures in a row it carries.
Esquema de entrada
{'type': 'object', 'required': ['id'], 'properties': {'id': {'type': 'string', 'description': 'Task id (UUID), as returned by create_task or list_tasks.'}}, 'additionalProperties': False}
list_destinations
List your destinations
The URLs you have claimed and whether each is verified. The signing secrets are never shown again.
Esquema de entrada
{'type': 'object', 'properties': {}, 'additionalProperties': False}
list_tasks
List your scheduled tasks
Your tasks and their state. Needs your management token as an Authorization header on this connection.
Esquema de entrada
{'type': 'object', 'properties': {'after': {'type': 'string', 'description': 'Cursor from a previous page.'}, 'limit': {'type': 'integer', 'description': 'How many to return.'}, 'state': {'type': 'string', 'description': 'Filter by state: live (default), all, or one exact state such as active or paused_by_client.'}}, 'additionalProperties': False}
pause_task
Pause a task
Stop firing until you resume. Nothing is charged while a task is paused.
Esquema de entrada
{'type': 'object', 'required': ['id'], 'properties': {'id': {'type': 'string', 'description': 'Task id (UUID), as returned by create_task or list_tasks.'}}, 'additionalProperties': False}
register_destination
Register a destination URL
Claim an https:// URL you control. We answer with a challenge and a SIGNING SECRET that is shown ONCE and never again — store it before you do anything else; it is what lets you verify that a delivery really came from us. The permission covers that path and everything beneath it, nothing above. Verification is one request from us to the exact URL you registered: POST, headers X-402cron-Challenge: <value> and X-402cron-Event: verify, JSON body {"challenge":"<value>"}. Reply within 5 seconds, without a redirect, with a body that is the bare value or {"challenge":"<value>"}; we read the first 512 bytes and do not check the HTTP status (2xx is fine). Then call POST /api/destinations/{id}/verify within 15 minutes of registering. A fixed-response webhook cannot pass: you need an endpoint you can program. Registering a URL that is still pending issues a new challenge and a new signing secret every time — the old secret immediately stops verifying deliveries; a verified URL is left untouched unless you add ?rotate=1. The daily verification allowance (10 per destination, 40 per client, UTC day) does not reset on re-registration.
Esquema de entrada
{'type': 'object', 'required': ['url'], 'properties': {'url': {'type': 'string', 'description': 'The https:// URL you control.'}}, 'additionalProperties': False}
restore_task
Restore a deleted task
Bring a task back from the recycle bin within 30 days. It comes back PAUSED — resume it explicitly.
Esquema de entrada
{'type': 'object', 'required': ['id'], 'properties': {'id': {'type': 'string', 'description': 'Task id (UUID), as returned by create_task or list_tasks.'}}, 'additionalProperties': False}
resume_task
Resume a paused task
Start firing again on the schedule. Refused if your balance is empty — buy deliveries first.
Esquema de entrada
{'type': 'object', 'required': ['id'], 'properties': {'id': {'type': 'string', 'description': 'Task id (UUID), as returned by create_task or list_tasks.'}}, 'additionalProperties': False}
run_task_now
Fire a task once, right now
Deliver immediately, outside the schedule. THIS COSTS ONE CREDIT per attempt, exactly like a scheduled firing, and a timeout or unreachable host is retried up to three times — so one call can cost up to three credits. Use it to test a destination.
Esquema de entrada
{'type': 'object', 'required': ['id'], 'properties': {'id': {'type': 'string', 'description': 'Task id (UUID), as returned by create_task or list_tasks.'}}, 'additionalProperties': False}
update_task
Edit a task
Change the schedule, destination, method, timeout, headers or body of an existing task. Omit a field to leave it unchanged — sending null is refused, because "unchanged" and "cleared" must not look the same. State is NOT editable here: use pause_task and resume_task.

It must already be registered and verified — see register_destination.'}, 'body': {'description': 'The body we send. Stored in the clear, so it must not carry credentials.

Answer 202 and do the work behind it.'}}, 'additionalProperties': False}
verify_destination
Verify a registered destination
Verification is one request from us to the exact URL you registered: POST, headers X-402cron-Challenge: <value> and X-402cron-Event: verify, JSON body {"challenge":"<value>"}. Reply within 5 seconds, without a redirect, with a body that is the bare value or {"challenge":"<value>"}; we read the first 512 bytes and do not check the HTTP status (2xx is fine). Then call POST /api/destinations/{id}/verify within 15 minutes of registering. A fixed-response webhook cannot pass: you need an endpoint you can program. Registering a URL that is still pending issues a new challenge and a new signing secret every time — the old secret immediately stops verifying deliveries; a verified URL is left untouched unless you add ?rotate=1. The daily verification allowance (10 per destination, 40 per client, UTC day) does not reset on re-registration. Until this passes, no task may point at the destination.
