get_pricingWhat 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_docsOne section of the machine documentation: quickstart, headers, signature, notice, errors, billing or limits. Omit `section` to get the whole document.
get_service_statusWhether 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_tasksYour tasks and their state. Needs your management token as an Authorization header on this connection.
get_taskA single task: schedule, destination, state, next run, and how many failures in a row it carries.
create_taskRegister 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.
update_taskChange 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.
pause_taskStop firing until you resume. Nothing is charged while a task is paused.
resume_taskStart firing again on the schedule. Refused if your balance is empty — buy deliveries first.
run_task_nowDeliver 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.
delete_taskMove 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.
restore_taskBring a task back from the recycle bin within 30 days. It comes back PAUSED — resume it explicitly.
register_destinationClaim 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,
verify_destinationVerification is one request from us to the exact URL you registered: POST, headers X-402cron-Challenge: and X-402cron-Event: verify, JSON body {"challenge":" "}. Reply within 5 seconds, without a redirect, with a body that is the bare value or {"challenge":" "}; we read the first
list_destinationsThe URLs you have claimed and whether each is verified. The signing secrets are never shown again.
delete_destinationRemove a claimed URL. Refused while a task still points at it — delete the task first.

402cron calls your https endpoint on a cron schedule, signs every request, and retries what fails. An agent can set it up on its own: no account, no card, no human in the loop. Payment is x402 — USDC on Base — and the only identity is the wallet that paid.
This repository holds documentation and runnable examples. The service runs at
https://402cron.com; its source code is not published.
?section=quickstart)com.402cron/402cron| Pack | Price | Deliveries | Per delivery |
|---|---|---|---|
trial | $0.02 | 20 | $0.001 |
starter | $1 | 2,000 | $0.0005 |
month | $25 | 50,000 | $0.0005 |
The balance counts deliveries, not money, and never expires. Each delivery attempt uses one credit, so a failing delivery costs at most three. Current prices: https://402cron.com/api/pricing.
GET https://402cron.com/buy/trial answers 402 with the price in the PAYMENT-REQUIRED header. Pay with any x402 client. The receipt carries your management token, shown once.POST /api/destinations with {"url": "https://your.host/hook"} returns the destination id and its signing secret, shown once.POST /api/destinations/{id}/verify. We POST a challenge to your URL and your endpoint echoes it back. The permission then covers that path and everything below it.POST /api/tasks with {"name", "url", "cron", "body"}. The response shows the next three runs.Management calls take Authorization: Bearer . Lost the token? Buy again from the same wallet with ?rotate=1; the old token stops working.
Three kinds of requests arrive at the same URL. X-402cron-Event tells them apart:
X-402cron-Event | When | Signed | Your endpoint should |
|---|---|---|---|
verify | once, when you call /verify | no | answer with the X-402cron-Challenge value as the body, within 5 s |
delivery | on schedule, on retries, and when you call /run | yes | check the signature and answer 2xx within 2 s |
task_paused | once, when a task pauses | yes | read reasonCode, fix the cause, POST the resume URL |
The signature is X-402cron-Signature: sha256= , an HMAC-SHA256 keyed with your signing secret over the bytes of:
{X-402cron-Timestamp}\n{X-402cron-Delivery-Id}\n{X-402cron-Attempt}\n{METHOD}\n{path+query}\n{raw body}
The event label is not signed: branch on it, but trust what the signature covers. Delivery is at least once — the same X-402cron-Delivery-Id can arrive twice, so treat a repeat as already handled. Deliveries also carry X-402cron-Task-Id and X-402cron-Deliveries-Left.
4xx or 5xx is your server's answer, so it is not retried.task_paused notice; resuming is one call.cron: 5 fields, always UTC, one minute at the finest. Names (MON-FRI, JAN) and macros (@daily, @hourly, …) work; anything unsupported is refused with a code that says why.https://.All limits: https://402cron.com/docs?section=limits
| Folder | What it is | Run |
|---|---|---|
receiver/node | a destination endpoint, no dependencies | SECRET_402CRON=… node server.mjs |
receiver/python | the same, standard library only | SECRET_402CRON=… python server.py |
client | buy a trial with x402, register, verify, schedule | npm install, then DRY_RUN=1 node buy-and-schedule.mjs |
Both receivers answer the challenge, verify signatures, drop duplicate deliveries and log pause notices. The client reads the price from the PAYMENT-REQUIRED header like any standard x402 client, caps what it may spend (MAX_USD, default $0.05), and with DRY_RUN=1 signs without paying anything. On Windows PowerShell, set variables with $env:SECRET_402CRON="…" first.
Claude Code:
claude mcp add --transport http 402cron https://402cron.com/mcp --header "Authorization: Bearer <token>"
Other clients: add a remote (streamable HTTP) server at https://402cron.com/mcp with the same header. get_pricing, get_docs and get_service_status work without a token. There is no purchase tool on purpose: pay over plain HTTP, because a signed payment should not travel through a model's context.
