Calculates when a legal deadline ends in Germany (Fristende, due date) under §§ 187-193 BGB, the German Civil Code: event vs commencement start (§ 187), end by days/weeks/months/years including a missing day of month (§ 188), and postponement to the next working day when it falls on a Sunday, Saturday or public holiday (§ 193). With a federal state the statewide holidays are honoured, without one only Sunday/Saturday; that limit is stated. Returns an end date, not a count of working days.

JPYC Service Monitor: weekly change feed for Japan-related JPYC and Web3 services. Each event is dated, typed (added / updated / removed / verified) and tied to an official source URL. Call with changedSince=YYYY-MM-DD set to your last run date to fetch only what changed; an empty changes list explicitly means no change, so a scheduled agent can report that without guessing. Without changedSince you get the full monitor snapshot.

IPIntel.ai x402 Tools package. Satellite Observation API for satellite imagery from coordinates, radius, mode and date. Supports true color, vegetation, water, thermal and radar modes with cloud-aware fallback. Uses Sentinel/Copernicus data from 2017 to present for earth observation, OSINT, site monitoring and change-over-time analysis.

Buy a live status line install for a team. Returns the client script file(s), config snippets, and step-by-step instructions for the installing agent to execute locally. The response token makes the line endpoint work and re-downloading the same bundle via /api/bundle is free — never pay twice for a retry.

Check a software package before installing it: whether it exists at all (AI coding assistants sometimes invent names), latest version and release date, package age, number of versions, weekly downloads (npm), licenses, deprecation, and known security advisories with severity. Returns a verdict of ok, caution or not-found with the reasons. Covers npm, PyPI, Cargo, Go, Maven and NuGet. Use before adding a dependency or running an install command.

Decide whether an agent-authored bash command complies with an execution policy, using a real shell tokenizer rather than pattern matching. Catches recursive deletes, force pushes, cluster and infrastructure teardown, raw device writes, path escapes, privilege escalation, and curl-piped-to-shell through pipelines, substitutions, quoting games and base64. Returns reason codes with spans and an optional short-lived permit bound to the exact canonical command. Never executes anything.

Annotate an image with detections using supervision's annotators (box, round_box, box_corner, circle, dot, ellipse, triangle, label, color, mask, polygon, halo, background_overlay, blur, pixelate, percentage_bar), applied in order. Input: base64 image up to 4 megapixels, up to 500 detections with xyxy pixel boxes and optional class_id, confidence, ASCII label, polygon. Returns the annotated image (base64 PNG or JPEG), size and counts per class.

Sandboxed JS execution ($0.05) — run a JavaScript snippet in an isolated child process (64MB heap cap, no network, no filesystem) and get the result plus captured logs. Pragmatic sandbox, not a hardened enclave. Toll: $0.05 USDC on Base or Solana.
