Early-warning system for risk and intelligence agents. Combines GDELT sentiment, World Bank governance data, and open-source intelligence to detect pre-crisis conditions before they break: coups, currency crises, unrest.

Threat-intelligence brief for any industry and region — active threat-actor campaigns, TTPs, nation-state APTs, eCrime/ransomware operators, and MITRE ATT&CK mapping, with recent CISA KEV and GDELT-scored news coverage. Worldwide sector-specific context, for threat-intel and SOC agents.

Signed conformance report over a whole x402 service. Sweeps every paid endpoint the service declares, GET and POST alike, runs the same checks /v1/preflight runs on each, grades the result, and returns an ed25519-signed report the operator can publish and anyone can verify offline. Coverage is inside the signature, so a partial sweep can never be passed off as a full one. Retrieving any report is free forever.

Curated on-chain registry lookup for Robinhood Chain stock tokens: 20 equities and 5 ETFs with canonical contract addresses sourced from official documentation, plus chain id, public RPC endpoint, and block explorer. Deterministic and cacheable — the same catalog every call until the registry is re-verified.

Would-you-rather question generator: 120 curated dilemmas across categories including an agents-and-ai set written for AI audiences (infinite context vs zero latency), plus tech, philosophy, silly, food, adventure, and superpowers. Returns 1-5 random questions, optionally filtered by category. Clean content, no duplicates.

Calculates the great-circle distance between two GPS coordinates in kilometers, miles, and nautical miles, plus the initial compass bearing from point A to point B. For delivery routing, flight-distance estimates, and logistics agents that need an exact figure rather than an eyeballed map distance.

Distance calculator API: great-circle (haversine) distance between two coordinates in km, miles, and nautical miles, plus initial compass bearing. Deterministic and auditable — cheaper than burning reasoning tokens, zero arithmetic-hallucination risk, and the result can be cited. For logistics, travel, delivery, and geo agents. Pairs with /geocode-city for name inputs.

Unit converter API: length, mass, volume, temperature, area, speed, pressure, energy, power, and digital storage — 100+ units, exact factors. Deterministic and auditable — cheaper than burning reasoning tokens, zero arithmetic-hallucination risk, and the result can be cited.

Just the user's pinned tweet, if any. Example: GET /api/jack/pinned

The users that belong to a list (paginate with cursor until has_more is false). Example: GET /api/lists/84839422/members

Tweet search for a hashtag. Same as `/api/search?q=%23tag`. Example: GET /api/hashtag/typescript

Percentage math calculator: find what X% of Y is, what percent one number is of another, or the percent change between two values. Built for pricing markups, discount math, grading, tipping, and reporting agents that need the exact figure instead of mental-math rounding errors.

Agent fortune API: a fortune cookie written specifically for AI agents ('A cached response is worth two upstream calls'), plus a lucky number and lucky HTTP status code. The cheapest, most delightful way to make your first x402 payment and verify your wallet stack works end to end. New fortune every call.

Computes a SHA-256 digest of any input text and returns it as a hex string, computed locally with no network round-trip to a third party. Also supports SHA-512, SHA-1, and MD5 on request. Useful for content fingerprints, cache keys, and deduplication logic where the same input must always produce the exact same output.

Produces an MD5 hash, or SHA-1, SHA-256, SHA-512 on request, of any text input as a hex digest, computed instantly with nothing stored. Useful for legacy checksum compatibility, quick fingerprinting, and integrity checks in pipelines that still expect an MD5 value alongside newer algorithms.

Temperature conversion API: any of Celsius, Fahrenheit, Kelvin, or Rankine to all four at once. Science-grade, exact.

Converts a given local time between IANA timezones with daylight-saving transitions applied correctly, so a meeting scheduled across the DST changeover lands on the right hour instead of one off. Returns local time, UTC ISO, and unix epoch for downstream calendar and reminder systems.

Timezone converter API: convert a wall-clock time from one IANA timezone to another with daylight-saving applied correctly — returns converted local time, UTC ISO, and unix epoch. 'What is 3pm Tokyo for Chicago?' deterministically. For scheduling and calendar agents.

School selection guide for parenting and education agents worldwide. Compares state/public vs private/independent vs charter/academy/international options by location, grade, and priorities. Ofsted (UK), My School (Australia), GreatSchools/Niche (US) ratings — which school is right for my child?

Practice quiz / practice problems / self-test generator for any K-12 topic. Returns multiple-choice quiz questions with answer explanations by grade, subject, topic, and difficulty (easy/medium/hard/mixed).

Meal prep planner / batch cooking planner / cook-once-eat-all-week schedule. Turns a set of meals and servings into a parallel prep schedule, storage and shelf-life times, and reheating instructions for weekly meal prep. Worldwide.

Medical bill negotiation and hospital-bill reduction strategy. Returns charity-care options, No Surprises Act protections, an itemized-bill review, and negotiation scripts to lower the bill. For debt-relief and patient-advocate agents.

Veteran education benefits guide for veteran and VA-benefits agents. Compares the GI Bill, a housing allowance calculator, VR&E eligibility, and dependent transfer options.

How to vet and hire a contractor: licensing and insurance checks, contractor red flags, and a contract checklist by trade (roofing, electrical, general contractor, and more). For homeowner and renovation agents. Returns license/registration-board lookup guidance, insurance requirements, payment-schedule guidance, and red flags, localized by location and country/jurisdiction when provided.
