How this service works
Deterministic, dependency-free data utilities served over x402 micropayments (USDC on Base). None of these call another AI model. Keyword: JSON repair Keyword: malformed JSON Keyword: broken JSON from LLM Keyword: fix JSON output Keyword: JSON sanitizer Keyword: truncated JSON recovery Keyword: YAML to JSON Keyword: convert YAML Keyword: parse YAML config Keyword: cron next run Keyword: cron parser Keyword: when does cron run next Keyword: unified diff Keyword: line diff Keyword: text diff Keyword: HTML to text Keyword: extract links Keyword: extract emails Keyword: scrape text Keyword: whois lookup Keyword: domain registration Keyword: registrar Keyword: domain expiry date Keyword: RDAP Keyword: dns lookup Keyword: MX records Keyword: TXT records Keyword: A record Keyword: DNS over HTTPS Keyword: github repo stats Keyword: github stars Keyword: repository popularity Keyword: OSS project metadata Keyword: email validation Keyword: verify email address Keyword: check MX deliverability Keyword: email syntax Use case: repair a JSON code block wrapped in Markdown fences Use case: turn a docker-compose or CI YAML file into JSON Use case: compute the next UTC fire time of a cron expression Use case: produce a unified diff between two versions of a file Use case: strip HTML tags and pull out links, emails, and headings Use case: look up a domain's registrar, status and expiry before purchase Use case: check when a domain registration lapses Use case: resolve A, AAAA, MX, TXT or NS records for a hostname Use case: find a domain's mail servers and SPF TXT record Use case: compare GitHub repository stars, forks and activity for market research Use case: check whether an email address is well-formed and its domain accepts mail
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/nextrunWhen 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
