Resolve a coordinate to its IANA timezone and return the current UTC offset, local wall time, DST status, and short abbreviation. Query: lat (-90..90), lon (-180..180), at (optional ISO 8601 instant; defaults to now). Returns { tz, abbreviation, offsetMinutes, offsetHours, localTime, observesDst, isDst, januaryOffsetMinutes, julyOffsetMinutes, instant, source }. Polygon lookup against a CC0 timezo

Check if an agent's reputation is real: Sybil forensics for one ERC-8004 AI agent — reviewer concentration, ghost reviewers, burst detection. Is this agent's feedback bought? No account, no API key

Check GitHub's official status source for current incidents, component health, and scheduled maintenance before an agent retries, deploys, or escalates.

Chess Daily answer check — legally validates a complete UCI principal line against the pinned daily puzzle.

One original constraint card in the tradition of lateral-thinking decks: a short instruction, reversal or question you can apply to whatever is stuck, written fresh by a model at high temperature on every call. The cards are ours, never a card from any published deck. An optional {"topic": "…"} of up to 140 characters steers it and reaches the model as its own message. No pool, no cache, and nothi

mcp.digest, sold by Taifoon: 9 sellers behind this wall, the best-ranked one answers; code checks the answer before you are charged (a failed answer is not charged), Jev grades it after. Price 0.006795 USDC.

Should my agent pay this expensive x402 endpoint? Call it before a costly or repeated payment. Returns the go / caution / no_go verdict plus the full diagnosis, the endpoint's check history per day over 30 days, how reliable the seller's other endpoints are and whether the endpoint moved domains. Never pays the endpoint. Bulk: 1000 credits for $0.80 via /api/v1/credits.

Home battery storage ROI and payback calculator — Powerwall vs alternatives, backup-power value, with the IRA 30% tax credit and state incentives applied. For homeowner and solar agents.

Score up to 100 x402 endpoints in one call. For teams: per-agent spend limits and an audit trail at lumierepaycheck.org/subscribe.

Live USGS river-gauge tick, deterministic. Answers "what is the flow at this gauge right now", "is this river high or low vs this week". Returns the latest streamflow (discharge, cfs) and gage height (ft) for one USGS site plus the 7-day min/max range, reading count, site name and coordinates, straight from USGS instantaneous values. Unknown sites 404 before payment. No LLM, no key, public domain.

Use before paying an x402 endpoint you have not used before, when you cannot tell a working seller from a trap, a testnet address dressed as mainnet, or a listing whose price no longer matches its challenge. Returns a verdict — live, degraded, trap, testnet or dead — a 0-100 risk score, and the specific findings behind both, so an agent can decline a bad endpoint instead of learning about it by lo

Product recalls (US): is a product, brand, food, drug, medical device or vehicle (make, model, year) under an active FDA, NHTSA or CPSC recall? Severity on one scale, hazard, remedy and lot codes. RecallScout

Every agent and developer hits broken or confusing JSON. This tool handles the common headaches in one place: check whether JSON is valid with the exact error location, repair near-JSON with typos, pretty-print or minify, pull values out with a path expression, diff two documents, convert to and from YAML or CSV, produce a byte-stable canonical form for hashing, validate against a schema, and repo

Checks whether a URL/domain is safe to fetch, cite, or follow: flags phantom-squatted or typosquatted brand domains, unregistered or brand-new domains, and known malicious infrastructure (URLhaus). Returns an ALLOW/WARN/BLOCK verdict before your agent trusts the link.

Agent Reliability Network: ARN x402 PayGuard provides x402 payment security for autonomous AI agents. Check the seller before you pay with payment preflight and payment-challenge validation. Returns ALLOW, CAUTION, or BLOCK.

Verify one legal citation. Body: {"citation": "<string>"} - full ("Miranda v. Arizona, 384 U.S. 436 (1966)") or bare ("384 U.S. 436"); the case name enables mismatch detection. Deterministic: regex plus cache / local corpus / CourtListener, no LLM in the path. status=verified (name confirmed), suspicious (reporter resolves to a DIFFERENT case - the fabrication signature), or not_found. verified=fa

Evaluate a used car before purchase. Compares the asking price with up to 50 current dealer listings in Canada or the U.S., matched by year, make, model, mileage and optional trim/location. Returns robust median and quartile pricing, deal rating, confidence, sample size and risk flags. Use for fast used-car price checks.

Runs Python you send in a sandbox and returns its stdout, exit status, time and memory. Use it to execute code an agent wrote - a calculation, a parse, a transformation - without a machine, an account or an API key of your own.

YRUZ Site Audit: Website audit in one call: TLS certificate, security headers, HTTPS redirect, HTTP/2 and HTTP/3, compression, response time, redirects, SEO tags and AI-agent readiness (llms.txt, robots rules for AI bots, sitemap, structured data). Scores 0-100 per area with concrete fixes.

Email address check: verdict (deliverable_likely/risky/invalid) with reasons from syntax, MX/A records, disposable-provider list, role address, free provider, typo suggestion, SPF/DMARC/DKIM and domain age. Use when an agent is about to send to, sign up, or accept an email address and wants to avoid bounces, throwaway or mistyped addresses. One address per call; no SMTP mailbox probing.
