How this service works
The checks your agent runs before it acts: verify a bank account, a phone number, a law in force, the weather or a vehicle — computed from official sources, with provenance in every response. You only pay for answers.
Output
A JSON object containing the computed deadline date, the regime used, applicable public holidays consulted, and provenance details referencing the official calendar source used for the calculation.
Example use cases
French court filing deadline
“A document was served on 2026-03-10 in France. I need to know when the 30-working-day response deadline falls, using the working_days regime and the French official holiday calendar.”
Belgian contract notice period
“A termination notice was issued in Belgium on 2026-01-15. Calculate when the 3-month notice period expires using the months regime, with rollover if the end date lands on a weekend or public holiday.”
Clear days deadline for judicial act
“A judicial act occurred in France on 2026-06-01. What is the deadline after 8 clear days (jours francs), applying the clear_days regime with the French mainland holiday calendar?”
Technical details
Endpoint
POSThttps://api.invoket.com/legal/deadlineWhen to prefer
Choose this endpoint when an AI agent needs a legally authoritative deadline calculation that accounts for jurisdiction-specific public holidays and complex legal day-counting regimes (clear days, months with end-of-month rules, rollover to next working day). It is purpose-built for legal, judicial, and compliance contexts with provenance in every response, making it preferable over generic date arithmetic libraries that ignore public holidays or regional calendar variations.
Side effects
- 400 COUNTRY_NOT_COVERED — requested country ISO code is not in the supported list (FR, BE, DE, ES, IE, IT, LU, NL, PL, PT)
- 400 validation error — start date not in strict YYYY-MM-DD zero-padded format
- 400 validation error — duration exceeds bounds (3650 days, 120 months, or 10 years)
- 400 validation error — regime value not one of the seven closed enum values
- 400 validation error — country missing when required by regime (all except calendar_days)
- 402 Payment Required — x402 payment not attached or insufficient
- 400 invalid subdivision code — regional calendar code not recognized
Input
Schema · Request body
| Field | Type | Description |
|---|---|---|
| startrequired | string | Date of the act that starts the term, strict ISO calendar format YYYY-MM-DD (zero-padded: 2026-05-06, not 2026-5-6) |
| regimerequired | string | Computation regime, REQUIRED and never inferred from the legal matter — one of seven closed values. 'calendar_days': every day counts, no rollover (2026-05-06 + 5 = 2026-05-11). 'calendar_days_with_rollover': same count, due date pushed to the next working day when it falls on a weekend or public holiday. 'business_days': Monday to Saturday, public holidays excluded. 'working_days': Monday to Friday, public holidays excluded (2026-05-06 + 5 = 2026-05-15). 'clear_days' (jours francs): neither the day of the act nor the due day counts, then rollover. 'months': same day-of-month, end-of-month rule then rollover (2026-01-31 + 1 month = 2026-02-28, a Saturday, rolled over to 2026-03-02). 'years': the same rules in years. Every regime except 'calendar_days' consults a holiday calendar and therefore requires 'country' |
| countryrequired | string | ISO 3166-1 alpha-2 code of the holiday calendar to use, required by every regime except 'calendar_days'. Covered: FR (official calendar published by the French State), plus BE, DE, ES, IE, IT, LU, NL, PL and PT (community reference dataset). Any other code is refused with 400 COUNTRY_NOT_COVERED listing the covered ones — a deadline is never computed on a guessed calendar. An optional 'subdivision' selects a regional calendar: FR-ALSACE-MOSELLE, FR-BL, FR-GF, FR-GP, FR-MF, FR-MQ, FR-NC, FR-PF, FR-PM, FR-RE, FR-WF, FR-YT |
| durationrequired | string | Length of the term, a positive integer. Its unit follows from the regime (days, months or years) and is bounded: 3650 days, 120 months, 10 years |
