How this service works
Keyless, pay-per-call compliance & regulated-data API for AI agents — OFAC wallet + sanctions/PEP + KYB screening, SEC filings, FRED economics, FDA recalls, federal awards, plus continuous monitoring. USDC on Base/Solana via x402, native MCP. No API key, no signup.
Output
Returns the estimated due date, trimester (first/second/third), gestational age in days and weeks, the LMP date used, the as-of date, and the calculation method (Naegele's rule).
Example use cases
Example prompt
“My last menstrual period started on March 3, 2025 — can you calculate my pregnancy due date and tell me what trimester I'm in?”
Technical details
Endpoint
GEThttps://api.gocreativeai.com/v1/calc/due-date/%7Barg%7DWhen to prefer
Use this endpoint when you need a quick, accurate pregnancy due date estimate based on the last menstrual period date using the standard Naegele's rule method. Prefer this over general health APIs when you specifically need gestational age breakdown and trimester classification with no signup or API key required.
Side effects
- Invalid date format returns an error — must be YYYY-MM-DD
- Missing required 'input' query parameter returns 400
- Future LMP dates may return unexpected or invalid gestational ages
- Dates far in the past may produce nonsensical trimester values
