SYNTHORA github-repo-activity: Activity metrics for any public GitHub repo (input owner/repo): stars, forks, open issues, last push, language, archived flag. 10-min in-process cache, stale-on-rate-limit or ok:false. Source: api.github.com, keyless.

One HTTP request per host, matched against an in-house signature set. Every hit carries a confidence value from 0 to 100 and the evidence it rests on: response header, asset path, cookie name, meta generator, DNS or ASN record. Results are cached for 24 hours per host, so a repeat lookup of the same domain answers from cache.

Weather forecast for any coordinates worldwide: current conditions plus a condensed hourly forecast (temperature, wind, humidity, precipitation, condition codes) and a will-it-rain summary. Official MET Norway model data (the institute behind yr.no) — commercial use permitted, attribution included. $0.002 per call.

Search every tracked DeFi yield pool with TVL over $50k: filter by chain, project, token symbol, stablecoin-only and minimum TVL, ranked by APY with base/reward split and IL risk. Open DefiLlama data, refreshed server-side every 15 minutes. $0.002 per query — the yield screener as a pay-per-call primitive.

Turn messy text into strict JSON: send text plus the fields you want and get back exactly those keys, null for anything the text does not state — never invented. Invoices, emails, contracts, scraped pages, chat logs....

IP geolocation / IP address lookup: city, region, country and coordinates, the network's ASN and organisation, reverse DNS, and whether the address is public, private or reserved. IPv4 and IPv6. Location data from DB-IP Lite (CC BY 4.0, credited), updated monthly; location is the network's registered place, never a street address. Input: ip.

Email verification / email validation: will mail to this address arrive? Checked live at the source: syntax, the domain's DNS (MX, null MX, no such domain) and its own mail server, asked whether the mailbox exists and whether it accepts any address (catch-all). No message sent. Flags disposable domains, role accounts (info@), free providers and typos (gmial.com). Verdict: deliverable, undeliverable, risky or unknown, with the reason. Input: email.

Phone number validation and lookup: valid or not, country and area, the carrier the range was issued to, line type (mobile, landline, toll-free, VoIP, premium), time zones and E.164, international and national formats, from Google's libphonenumber numbering plans. Nothing is dialled and the owner is never looked up. Input: number; optional region for a national-format number.

BTC and ETH market-cap dominance (% of total crypto market cap), plus total market cap and active-coin count, refreshed every ~5 min. Use to gauge whether capital sits in majors vs alts. For the alt-rotation read specifically, use /alt-season.

Deterministic IBAN check before a SEPA/international transfer: format regex, per-country length (public SWIFT registry, ~85 countries) and ISO 7064 mod-97 checksum. Query: ?iban=FR1420041010050500013M02606 (spaces/dashes tolerated). Returns valid, country, bban, and a precise failure reason. Pure offline computation, 1y cache.

Hourly weather forecast for any point on Earth from Open-Meteo (blend of ECMWF/GFS/ICON models, refreshed hourly; data CC-BY 4.0). Query: ?latitude=48.8566&longitude=2.3522&hourly=temperature_2m,precipitation,wind_speed_10m&forecast_days=2 (1-16 days, ~80 hourly variables available, optional daily= aggregates and timezone=auto). ISO 8601 time arrays + units. 15 min cache.

French address geocoding on the official Base Adresse Nationale (api-adresse.data.gouv.fr, Etalab/IGN, continuously updated). Forward: ?q=8 boulevard du port amiens with optional &type=housenumber|street|locality|municipality &citycode=80021 (INSEE filter). Reverse: ?lat=49.897&lon=2.290. &limit=1-10 (default 3). Each match returns normalized label, confidence score, lat/lon, street, postcode, city, INSEE citycode and context. No match returns 400 (not billed). Cached 24h.

Official French administrative reference from geo.api.gouv.fr (INSEE/IGN data). Look up communes by ?cp=31700 (postal code), ?code=31056 (INSEE), ?nom=Blagnac (fuzzy name) or ?lat=43.63&lon=1.37 (commune containing a point). Returns up to 20 communes with name, INSEE code, population, postal codes, departement, region and EPCI. The postal-to-INSEE mapping is the pivot key for joining French territorial datasets. Cached 7 days.

Security headers check for a website: audits HTTPS, HSTS, Content- Security-Policy (CSP), X-Content-Type-Options, X-Frame-Options / clickjacking protection, Referrer-Policy and CORS from the real HTTP response of any live URL. Findings with severity for what is missing. Header posture only, not a penetration test.

Website accessibility audit (a11y, WCAG compliance check): WCAG 2.1 level A and AA conformance of any live URL or raw HTML, tested with axe-core in a real headless browser. Returns every violation with rule id, impact, help text and affected node count. Deterministic rules; a check that cannot run returns an error, never a pass.

Is this email address worth sending to? Syntax, domain DNS (MX, then A/AAAA), disposable/role/free-provider lists, a typo suggestion (gmial.com -> gmail.com), a normalized form and a risk verdict with reasons. No SMTP probe: it vouches for the domain, never the mailbox. An invalid address is a paid verdict; a DNS failure is 502, not charged. Pay-per-call via x402. An empty body is answered for the published example address (name@example.com); send {"email":"…"} for any other address.

Returns the outstanding cross-border positions of banks located in a reporting country against counterparties in another, from the BIS locational banking statistics, split into claims and liabilities and never netted silently. The separation matters: a jurisdiction showing large claims and large liabilities is intermediating, not lending, and reporting only a net figure hides the gross exposure that actually fails in a crisis.

Deterministic 8-bit SFX synthesis from a preset + seed — base64 WAV plus the reproducible SFXR parameter block

Mutate a known-good seed's sound (classic sfxr mutate) — nearby variations by parameter perturbation

Selects supplied official import-document requirements for code and origin. Missing facts are returned as null and named in unavailable_fields where applicable. Derived values disclose their method; source-backed values disclose source, time window and age. This is neither legal advice nor customs advice.

Multiplies installed quantities by supplied waste-adjusted production factors and adds tonne-kilometre transport factors. It reports a transparent partial embodied-carbon inventory only; it does not supply verified EPD data, include use/end-of-life stages unless represented by inputs, compare functional equivalence or constitute a certified life-cycle assessment.

Compares scalar confidence with binary correctness, calculates mean squared Brier loss, partitions confidence into caller-selected equal-width bins and reports expected and maximum calibration error. It does not validate labels, correct class imbalance or prove calibration beyond the supplied sample.

DNS and list based verification. Never claims that a mailbox exists without evidence: without an SMTP probe the verdict for a routable address is "unknown", not "valid".
