Cron402

Schedule webhook calls, pay per run in USDC on Base via x402. Ten tools, built for small models.

Quick Install

Automated & IDE Setup

Copy the AI prompt to install this server into Claude Code, Cursor, or another agent — or use 1-click editor setup below.

One-click editor setup isn’t available for this listing yet — we don’t have a confirmed install command, and we’d rather show nothing than point your editor at the wrong package or host. Follow the project’s own setup instructions, linked above.

Manual Client & Custom JSON ConfigExpand JSON ▾

No confirmed setup config for this listing yet. We only publish a config block when the install details come from the project itself — its README, its docs, or a verified owner. We haven’t found those for cron402, and we’d rather show nothing than a guess you’d paste into your client. Follow the project’s own setup instructions for the current steps.

Documentation Overview

Price: $0.008 flat per run
Network: Base mainnet (eip155:8453) — validated end-to-end on Sepolia first (settlement tx 0x01f7bed4…)

How scheduling works

Every job gets its own Durable Object (CronJobDO). A cron-parser-computed next-run time is set as the DO's alarm() — exact to the minute for arbitrary cron expressions.
Each fire: dispatch the target webhook (10s timeout) → up to 3 attempts with backoff → log the execution to D1 (kept: last 100 runs / 30 days per job) → consume 1 credit.
Auto-pause rules: 3 consecutive failures → paused; zero credits → exhausted.
A global Worker Cron Trigger (* * * * *) sweeps for missed alarms as a safety net.
Top-ups reactivate paused/exhausted jobs automatically.

How payments work

Paid endpoints are gated by @x402/hono v2 middleware:

Agent calls the endpoint with no auth.
Server responds 402 Payment Required with instructions (price, network, payTo).
Agent signs an EIP-3009 USDC transfer from its wallet and retries.
The facilitator verifies + settles; settlement receipts land in D1.

Because the payer isn't online when an alarm fires, billing is prepaid run credits: creation includes 1 credit; packs of 1 / 10 / 100 cost $0.008 / $0.08 / $0.80. Credits never expire and top-ups are permissionless (anyone can fund any job).

Management actions (pause/resume/delete) require an EIP-712 signature over ManageJob { action, jobId, timestamp } from the payer key (±5 min validity).

`POST /v1/crons`	x402	$0.008	Create job (body: `{ schedule, target: { url, method?, headers?, body? }, maxRuns? }`). Includes 1 run credit.
`POST /v1/crons/topup/1`	x402	$0.008	Add 1 credit (body: `{ jobId }`)
`POST /v1/crons/topup/10`	x402	$0.08	Add 10 credits
`POST /v1/crons/topup/100`	x402	$0.80	Add 100 credits
`GET /v1/crons/:id`	free	—	Job status, credits, last 20 executions
`POST /v1/crons/:id/pause`	wallet-signed	—	Pause job
`POST /v1/crons/:id/resume`	wallet-signed	—	Resume job (requires credits)
`DELETE /v1/crons/:id`	wallet-signed	—	Delete job
`GET /health`	free	—	Liveness probe
`POST /v1/echo`	free	—	Test target for smoke tests

Signed requests add two headers:

x-cron402-timestamp: unix ms (valid ±5 min)
x-cron402-signature: EIP-712 signature, domain { name: "cron402", version: "1" }, primaryType ManageJob

Limits & policies (v1)

Min interval: 1 minute · Max 1,000 active jobs per payer wallet
Retry policy: 3× with 1s/3s/8s backoff; non-retryable 4xx (except 429) fails immediately
Log retention: last 100 executions or 30 days per job, whichever trims first

Network: Base mainnet (eip155:8453) — flipped from Sepolia after a fully verified paid run. Receiving wallet secret PAY_TO_ADDRESS is set on the Worker. Facilitator: Coinbase CDP hosted (CDP_API_KEY_ID/CDP_API_KEY_SECRET secrets set; JWT auth implemented in src/cdp-auth.ts). D1 database cron402 (id b7e05d96-4737-4aa4-ab52-badcfacb3a22) holds the schema from both migrations.

Bazaar: bazaar extensions are declared via @x402/extensions/bazaar (info.input.type: "http"); listing appears after a successful CDP settle that echoes the extension — do not claim currently indexed until validated.

Execution webhooks

Pass optional notifyUrl when creating a job. After every fire, cron402 POSTs to it:

config.json

{
  "type": "cron402.execution",
  "jobId": "…",
  "runAt": 1755000000000,
  "ok": true,
  "attempts": 1,
  "statusCode": 200,
  "error": null,
  "durationMs": 42
}

Notifications are best-effort (10s timeout, never affect scheduling).

Human dashboard

/dashboard connects any injected EIP-1193 wallet (MetaMask etc.). Load a job by id to see status/credits/executions; pause/resume/delete request an eth_signTypedData_v4 signature over ManageJob — exactly what agents sign, just through a browser wallet.

MCP server (`cron402-mcp`)

Ten tools for any MCP client, designed so a small model can schedule a cron without burning money on mistakes:

Tool	Cost	Purpose
`cron402_guide`	free	The full procedure, prices and rules — what a model reads first
`check_wallet`	free	Address, network, USDC/ETH balance, runs affordable
`preview_schedule`	free	Validate a schedule, show the next 5 UTC run times
`create_cron`	$0.008	Create a job (includes 1 credit)
`topup_cron`	$0.008–$0.80	Add 1 / 10 / 100 credits
`get_cron`	free	Status, credits, last 20 executions
`list_crons`	free	Jobs created from this machine, with live status
`pause_cron` · `resume_cron` · `delete_cron`	free	EIP-712 signed management
