How this service works
Paste malformed JSON from ChatGPT, Claude or any model and get it repaired in your browser. Fixes code fences, trailing commas, single quotes, unquoted keys, Python True/False/None, comments and truncated output — and names every repair it made. Free, no signup, nothing uploaded.
Output
Returns a JSON object with `ok: true`, a `next` field containing the ISO 8601 datetime string of the next cron execution, and `epochMs` with the corresponding Unix timestamp in milliseconds.
Example use cases
Verifying a weekly report cron
“My weekly report job uses the cron expression '0 8 * * 1' — when exactly will it next fire? I need the ISO timestamp so I can set a reminder.”
Debugging a monthly billing schedule
“We trigger billing with '0 0 1 * *', can you tell me the next time that cron will run and give me the epoch milliseconds too?”
Scheduling a pipeline alert window
“Our data pipeline runs on '*/15 * * * *' — what's the next scheduled execution time so I know how long to wait before alerting?”
Technical details
Endpoint
POSThttps://penniless-json-repair.sjaman.workers.dev/cron/nextrun?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a fast, deterministic, dependency-free cron next-run calculation without calling an AI model. Ideal for CI/CD pipelines, scheduling agents, or devops automations that need to programmatically know when a cron job will next execute. Costs only $0.001 USDC per call via x402 micropayments, making it suitable for high-frequency or automated use.
Side effects
- Invalid or malformed cron expression returns an error response
- Missing `input` body field causes a 400-level error
- Ambiguous timezone handling may produce unexpected results if timezone is not accounted for in the cron string
- Truncated or incomplete cron fields (e.g. only 4 parts) may fail parsing
