Cron next-run calculator — generate future times for bounded five-field POSIX cron schedules in IANA timezones with explicit daylight-saving (DST) policies.

Sunrise, sunset, solar noon, day length, civil/nautical/astronomical twilight and golden hour for Belgrade today (and tomorrow), computed for the city's coordinates and local timezone. Photography, outdoor scheduling and prayer-time helpers for Belgrade. $0.01 per call.

Timezone intelligence — offsets, DST, transitions

Convert a time between any two IANA time zones (DST-aware). Pay-per-call in USDC on Base.

Forward geocode a free-text address, place name, or city (e.g. "Tokyo, Japan") into geographic coordinates — latitude and longitude — plus its IANA timezone. Use this to convert a location description into coordinates for mapping, distance, or timezone-aware lookups, or as the first step before coordinate-based endpoints like weather forecasts.

Resolve one global city or locality name into bounded, population-ranked GeoNames coordinates, country and first-level-region identity, population, timezone, feature code, and source freshness without a request-time network call.

IP address geolocation -- city, country, org, timezone. Pass ?ip=8.8.8.8

Geolocate an IPv4/IPv6 address: country, region, city, postcode, lat/lng, timezone, ISP, org, ASN, and a datacenter heuristic.

Convert a timestamp between IANA timezones with DST handled correctly. Returns local times, UTC offsets, weekday, and hour-of-day per zone. POST { time?, from?, to } — to is a zone or array (max 20).

Resolve any public IPv4/IPv6 address (or hostname) to geolocation for analytics, fraud, and ops agents. Returns ISO country code, region, city, IANA timezone, latitude/longitude, EU membership flag, and the matched network range. Backed by an embedded MaxMind GeoLite2 dataset (no external API calls). Private and reserved IP ranges are rejected; no shell access.

Agent-Cron-Service: schedules a recurring trigger (crontab expression, timezone-aware) delivered to a verified webhook or email, paid per trigger in USDC. POST the job definition; the 402 quotes the exact price.

Fetch worship service times for one Reformed church by stable UUID. Only the schedule fields already shown on the public share page, plus name, place, timezone, and language. Base USDC, $0.01 per church.

Convert an explicit-offset ISO timestamp to an IANA timezone, including historical offsets. Price: $0.002 USDC per call.

Give it a latitude and longitude and it answers with what the nautical chart says about the water there: the depth range of the charted depth area containing the position, the nearest charted sounding and how far away it is, and the chart's own zone of confidence for that area. Parameters go in the query string: this is a GET, there is no body. NOT FOR NAVIGATION, stated first because it is a cond

Converts a local time in one IANA zone to up to 20 target zones. Returns local time, UTC offset, abbreviation and DST flag per target, and flags nonexistent or ambiguous local times at DST transitions.

Business-day arithmetic that respects weekends and a country's public holidays. Either add N business days to a date (SLA due dates, shipping ETAs) or count business days between two dates. Weekend days are configurable (e.g. 'fri,sat').
