Age in whole years. Use for eligibility checks and profile enrichment from a birthdate. Returns whole-year age from an ISO birthdate (not a legal ID check). $0.001 USDC per successful call via x402 on Base or Solana—deterministic first-party JSON, no API key, no subscription, and nothing is billed on structured validation errors.

Pretty-print JSON. Call before showing configs to humans or attaching readable debug dumps. Returns indented JSON text; invalid JSON returns a structured error. $0.001 USDC per successful call via x402 on Base or Solana—deterministic first-party JSON, no API key, no subscription, and nothing is billed on structured validation errors.

Mask sensitive middle characters. Use before logging secrets, account numbers, or tokens that must stay partially hidden. Returns a masked string suitable for audit trails—never stores the original beyond the request. $0.001 USDC per successful call via x402 on Base or Solana—deterministic first-party JSON, no API key, no subscription, and nothing is billed on structured validation errors.

Prime factorization. Use when agents need factorization for puzzles, crypto teaching, or ratio breakdowns (bounded n). Returns the factor list as structured JSON. $0.001 USDC per successful call via x402 on Base or Solana—deterministic first-party JSON, no API key, no subscription, and nothing is billed on structured validation errors.

UUID generator API for agents: generate one to ten UUIDv4 identifiers for $0.001 USDC. Call when you need correlation ids, idempotency keys, or object slugs without an ID service. Local first-party CSPRNG only—not a sorted ULID clock and not a reserved namespace. No API key, no subscription.

SHA-256 hash API for agents: hash text with SHA-256, SHA-1, or MD5 for $0.001 USDC and return a compact deterministic receipt—not a password KDF. Call when you need this bounded result without an API key or subscription. Returns machine-readable JSON via x402 on Base or Solana. Limitation: results cover only the supplied input or one bounded public endpoint at request time; callers must verify before acting.

Check whether an IP is inside a CIDR network for $0.001 USDC. Call when you need this bounded result without an API key or subscription. Returns machine-readable JSON via x402 on Base or Solana. Limitation: results cover only the supplied input or one bounded public endpoint at request time; callers must verify before acting.

Paid MCP endpoint — POST a JSON-RPC tools/call to get_content for public profile data (github, twitter, linkedin).

For a location, returns per facility type the nearest one with its distance and details, the count within the radius, and the density per square kilometre. Hospitals are additionally reported with whether they have an emergency department where that is tagged, since a hospital without one does not answer the question being asked. Defibrillators come with their access class and indoor flag, because one locked inside a closed office building at night is not available.

Queries OpenStreetMap for charging stations within a radius of a point and returns each with its position, distance, operator, network, connector types with their individual power ratings and socket counts, access restrictions, fee status, opening hours and whether authentication is required. Results are sorted nearest first and can be filtered to a minimum power or a required connector type, which is the question a vehicle actually has.

Examines the ways and barrier objects around a destination for anything that stops a vehicle getting there. Barriers such as gates, bollards, lift gates and cycle barriers are returned with their position, distance and whether they are locked. Ways carrying access tags are returned with the restriction and who it applies to, and physical limits — maximum height, weight, width and length — are compared against the vehicle dimensions you supply, so the answer is specific rather than a list to…

Searches OpenStreetMap for venues of a chosen kind near a coordinate and reports accessibility as the separate facts it actually consists of: step-free entrance, accessible toilet, lift, designated parking, plus entrance width and step count where recorded.

Builds a noise context for a site from what surrounds it. Roads within the radius are weighted by class, by recorded speed limit and lane count where present, and by distance with a falloff, because a motorway at eight hundred metres and a residential street at twenty are different problems. Railways are counted separately with their usage class, since freight lines at night dominate what people actually complain about.

Combines the registry view and the routing view of a prefix into one answer, keeping them apart because they are not the same thing and their disagreement is the finding. From the registry come the holder, the allocating authority, the registration and last-modified dates and the country as recorded, together with any route objects registered in an IRR. From routing come the origins observed over the requested window with the periods they were active, plus first and last sighting.

Business-day count excluding weekends and full-day Public or Bank holidays; Optional and HalfDay observances remain business days.

Add business days while skipping weekends and full-day Public or Bank holidays; Optional and HalfDay observances are retained.

Holiday date check by country or subdivision — determine whether one ISO date is an official public holiday.

Official public holidays by country and year, with regional subdivisions, localized names and normalized dates.

Next official public holiday after a date for a supported country or regional subdivision.

Chess Daily tactics puzzle — solve a deterministic UTC daily position from a pinned CC0 Lichess subset using legal UCI moves.

Twenty-Four daily math puzzle — four numbers to combine into exactly 24; deterministic solvable UTC daily challenge for agent reasoning benchmarks.

Gridlock daily maze — find an optimal orthogonal route through a deterministic bounded obstacle grid.

Trivia Daily knowledge challenge — answer one deterministically selected and shuffled question from a curated local set.
