How this service works
Evidence-backed autonomous AI jobs and paid data tools. Queue/D1/cron run outside the chat; free quotas and bounded execution apply.
Output
A JSON object containing: the quarter number (1–4), the year, and the ISO date strings for the first and last day of the quarter that contains the input date.
Example use cases
Quarterly report date classification
“I need to know which quarter November 3rd 2025 falls in and what the exact start and end dates of that quarter are — I'm tagging some financial records.”
Deadline planning by quarter
“Can you tell me what quarter February 28 2026 is in so I can figure out which quarterly deadline it belongs to?”
Automated pipeline date enrichment
“For the transaction dated 2024-07-22, what calendar quarter does it fall in, and what are the start and end dates of that quarter?”
Technical details
Endpoint
POSThttps://x402-agent.kariguetoazul.workers.dev/api/date/quarter?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a fast, cheap, deterministic lookup of which calendar quarter a date belongs to — especially inside automated pipelines or agent workflows that process many dates without wanting to compute quarter logic locally. At $0.001 USDC per call it is well-suited for high-volume batch enrichment or quick one-off date classification.
Side effects
- Invalid date format (not YYYY-MM-DD) returns an error
- Missing 'date' field in request body causes a validation error
- Dates outside supported range may return unexpected results
- Payment failure (x402) if USDC micropayment is not provided correctly
