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

Normalize a public Atlassian Statuspage into operational, maintenance, degraded, partial_outage, major_outage or unknown state, with components, active incidents and scheduled maintenance. V1 accepts an explicit status-page URL; it does not discover arbitrary providers or infer hidden service health.

Seller reputation by payTo address: how many endpoints it serves, how many are live, price range, clone-farm and quote-only flags, and on-chain activity on Base (settlements and unique payers over 30 days, last settlement time).

Agent-visibility check: does an AI crawler (GPTBot, ClaudeBot, PerplexityBot, OAI-SearchBot) actually see your site? BEST-RATE pack: 4 checks for $5 ($1.25/check). Same service, smallest entry $2 at https://402registry.com/buy/one. Ladder: 1/$2, 2/$3, 4/$5. All packs: https://402registry.com/.well-known/402registry.json. A passing check earns a dated badge and a registry listing. No account, no card, no human.

TLS certificate status for shopify.ca: issuer, common name, valid-from/valid-to, days until expiry and whether it is valid now, from certificate-transparency logs and a live HTTPS check, plus HSTS and redirect-to-HTTPS. Expiry watch for a site you depend on. $0.01 per check.

Cron preset "nightly 3am" (0 3 * * *): the next 10 run times in UTC from now (or from a start time you give), a plain-English description and the interval between runs. Grab the expression and its upcoming runs without writing cron syntax. $0.01 per call.

Pre-sign risk verdict plus a plain-language explanation in Dutch or English

Change watch for status page tailscale: runs the check, compares it with the result from your previous call for the same query (kept 90 days) and returns the current answer, changed true/false, the fields that changed with before/after values, and when it was last seen. Schedule it to be alerted when this changes. $0.02 per check.

Inspect a public URL with HEAD; GET only on 405/501. Return origin status, final URL, headers, cache validators and up to 5 redirects. Limits: 8s, 2 MiB. Origin 4xx/5xx are observations; length is unverified and SHA256 covers only complete GET bodies. No JavaScript, login or availability guarantee. 0.001 Base Sepolia test USDC per success; invalid inputs/errors are not settled.

Extract PDF/CSV/XLS/XLSX/ZIP/JSON/XML links from static public HTML by suffix or download filename. Resolve relative/base links and deduplicate. Limits: 500 links, 8s, 5 redirects, 2 MiB. No JavaScript or file downloads; existence, MIME, size and file safety are unverified. Empty results are valid. 0.003 Base Sepolia test USDC per success; invalid inputs/errors are not settled.

Wallet approval audit (green/orange/red, grade, one-line summary): every open ERC-20 allowance of an EVM wallet with who the spender is (flagged, plain wallet, unverified, unlimited) and which ones to revoke

Resolve a bare public domain into operational registration, DNS, HTTPS/TLS and mail-policy state using IANA-routed RDAP, DNS, MX/TXT/SPF/DMARC and a bounded TLS probe. No registrant personal data, vulnerability scanning, mailbox existence or deliverability claim. Provider uncertainty is explicit.

Read SMX (Space Markets Stage 1) testnet event markets on space milestones, e.g. Starship Flight 14 and The Moon Race, on Base Sepolia (eip155:84532): list markets, market detail, or mid price in cents. Each read costs $0.01 test USDC via x402. Test collateral has no monetary value. This API does not place orders: trading is wallet-signed from your own wallet per https://smx.space/skill.md. Docs: https://smx.space/llms.txt

Resolve a public GitHub release into the most plausible downloadable asset for a normalized OS/architecture target, excluding source/signature/checksum files and linking checksum companions when present. Returns ambiguity instead of silently choosing tied candidates. No private repositories or customer authentication.

Normalize npm or PyPI package reality: existence, requested-version existence, resolved/latest version, staleness, deprecation/yank state when available, license and runtime requirement. No dependency graph or vulnerability analysis. Public registries only; unsupported provider fields are null.

Perform a bounded static discovery pass for machine-usable documentation: llms.txt, Markdown alternates, developer/API/auth docs, OpenAPI/Swagger and MCP candidates. Candidates are returned only after bounded verification. Maximum 10 HTTP requests, no JavaScript, recursive crawl or authenticated content.

Is this token safe to buy, or a honeypot or rug pull? Checks a Solana or EVM token before you buy, hold or accept it (mint or freeze authority still active, LP not locked, buy/sell tax, low liquidity, brand-new token, concentrated holders) and answers green/orange/red with a grade (SAFE/CAUTION/RISKY/AVOID), the reasons, a one-line summary and market data

Returns a one-page research brief with cited source URLs, key findings and open gaps for a question. Call it when an agent needs a sourced answer instead of an unsourced guess. Input: {"question": "..."} (5-400 chars, any language).

Convert tabular data between CSV/TSV and a JSON array of objects, in either direction, with detected delimiter and typed columns. Use it when a tool returns CSV but your pipeline needs JSON (or the reverse) and you do not want to run a parser yourself.

Reviews source code and returns line-numbered findings with severity and a concrete fix, combining deterministic static rules (eval, SQL concat, secrets, shell injection) with an AI review. Call it before merging or running untrusted code. Input: {"code": "...", "language": "javascript"}.
