https://api.invoket.com/weather/forecast/batch

Before your agent plans across a whole network — fleet routing, multi-site operations, portfolio hedging: 2 m temperature, precipitation and 10 m wind forecasts for up to 500 point + lead-time queries in one call, from the deterministic NOAA GFS run (~16 days). Each query takes lat+lon or a city name plus an optional lead selector (omitted, it defaults to the current analysis time); an uncovered item is flagged via per-item coverage instead of failing the batch.

Buyer-side trust oracle for the x402 marketplace: 'I need X, budget $Y — which tool is real?' Sweeps the WHOLE catalog across many queries, collapses sybil/factory clusters (one wallet stamping many fake-distinct listings), ranks the genuinely-used survivors by unique-payer usage, and returns one vetted pick with a ready-to-pay challenge. The credit-bureau check an agent can't do in a single query.

https://2s.io/api/timezone/lookup

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 timezone boundary index; offsets and DST come from the runtime tzdata so transition rules stay current. Use when scheduling for a coordinate, converting timestamps to local wall time, or checking whether a location is currently observing daylight saving.

https://2s.io/api/calendar/holidays

List the official holidays for a country and year, with exact observed dates including substitute days (e.g. a Saturday July 4th observed on Friday). Query: country (ISO 3166-1 alpha-2, 200+ supported), year, optional region (subdivision code like CA for US-California or BY for DE-Bavaria), optional types filter (public, bank, school, optional, observance — comma-separated), optional lang (ISO 639-1) for localized names. Returns one item per holiday: { date (YYYY-MM-DD), name, type, substitute, rule }. Dates are computed from maintained per-country rules — including movable feasts and lunar-calendar holidays — so they stay correct year over year. Use for scheduling, delivery estimates, payment terms, and SLA math.

https://x402.fuchss.app/v1/x402-trust

Trust score (0-100, grade A-F) for any publicly listed x402 endpoint. Unlike uptime-only checkers, we return ECONOMIC PROOF: the REAL on-chain USDC settlement volume and distinct-payer count for the endpoint's payTo address — is anyone actually paying it, or is it just live? Computed deterministically from continuous monitoring: 30d probe uptime, 402-envelope spec compliance, latency, observed age, on-chain settlement activity, and advertised-price stability. Includes a full component breakdown, machine-readable flags, and an honest observedDays (we report only the history we actually have, with dataCompleteSince marking our gap-free on-chain coverage). Know before you pay.

https://2s.io/api/calendar/business-days

Holiday-aware business-day calculator for 200+ countries. Three modes: pass start + addDays (signed integer) to shift a date by N business days; pass start + end to count business days between two dates (exclusive of start, inclusive of end); pass start alone to check one date (is it a business day, which holiday, next/previous business day). Query: country (ISO 3166-1 alpha-2), start (YYYY-MM-DD), optional region (subdivision code), addDays XOR end, optional weekend (comma-separated days, default sat,sun — e.g. fri,sat for the Gulf), optional types (holiday types treated as closures, default public,bank). Skipped holidays are itemized in the response. Use for payment terms, SLA deadlines, and delivery-date math.

https://api.invoket.com/weather/forecast

Before your agent schedules a delivery, plans outdoor work or hedges short-term weather exposure: a point forecast of 2 m temperature, precipitation and 10 m wind — plus opt-in convective, humidity, cloud and snow variables — for any GPS point or city. Deterministic NOAA GFS at 0.25 deg to 16 days (384 h), NOAA GEFS ensemble mean at 0.5 deg to 35 days (840 h); the lead selector is optional (omitted, the forecast defaults to the current analysis time) and the response names the model that served it and the exact forecast step.

https://2s.io/api/convert/unit

Convert a value between units of measure: mass (g, kg, mg, lb, oz, t, st), length (m, km, cm, mm, in, ft, yd, mi), volume (l, ml, m3, gal, gal-imp, qt, pt, cup, floz, tbsp, tsp), area (m2, km2, ft2, acre, ha), and temperature (C, F, K). Units are matched case-insensitively with common aliases (kg/kilogram/kgs). Returns {value, from, to, dimension, result}. Exact factors — the ground-truth answer a CPG/ETL pipeline needs instead of an LLM approximating conversions. Cross-dimension conversions (kg→m) return 400.

https://entityresolver.xyz/resolve

Name in, official IDs out. Give it a company or crypto name or ticker ("Apple", "ETH", "Stripe") and get the verified IDs that identify it everywhere: SEC CIK + ticker, GLEIF LEI, Wikidata QID, CoinGecko slug. Every ID is pulled live from the entity's own official registry and tagged with the sources that agreed — so you can check it yourself, not trust an LLM's guess. Ranked by confidence.

https://kronossignals.com/api/v1/forecast/doge

Dogecoin (DOGE) price direction forecast. Kronos-base (60-path Monte-Carlo) ML model, cached ~20 min — switched from composite 2026-07-10. Measured on predictions actually served: 62% directional over 3,300+ scored DOGE forecasts — above our ~54% all-asset headline; verify per-asset at /api/stats (beta_accuracy). Falls back to the composite heuristic if the cache is briefly stale. Pay-per-call via x402 on Base USDC. Live scored track record at /api/stats — not a backtest.

https://2s.io/api/business/lei

Look up or search the global LEI (Legal Entity Identifier) registry — the authoritative ISO 17442 directory of ~2.6M legal entities worldwide. Pass `lei` for an exact 20-character LEI, or `query` to search by legal/other name (ranked best-match first). Filter name search by `country` (ISO 2-letter, HQ country) and `status` (active = currently active entities only; all = default). Each result returns the LEI, legal name, an alternate/other name, legal jurisdiction, entity category (GENERAL/FUND/BRANCH/…), ISO 20275 legal-form code, entity status (ACTIVE/INACTIVE), LEI registration status (ISSUED/LAPSED/RETIRED/…), headquarters city/region/country/postal code, the initial registration + last update + next renewal dates, and the managing LOU. Use this to canonicalize a company name to its LEI, resolve a counterparty, or enrich a vendor master. Data: GLEIF Golden Copy (CC0, public domain).

https://2s.io/api/medical/icd10

Verify and search ICD-10-CM diagnosis codes against the official US code set (FY2026, ~98k entries). Pass code (with or without the dot, e.g. E11.9 or E119) to confirm the code exists and list its more-specific child codes, or q to keyword-search code descriptions (e.g. "type 2 diabetes neuropathy"). Optional billable_only=true restricts results to codes valid for claim submission; limit caps results (1-50, default 10). Returns a verified flag, the exact match if any, and matched codes with billable status plus short and long descriptions. Data: CMS/NCHS ICD-10-CM (public domain), refreshed each US fiscal year. Use to confirm diagnosis codes are real and current before placing them in claims, prior authorizations, or clinical documents.

https://x402-store.dgdb.workers.dev/v1/listing-doctor

Why is my x402 service not listed in the Bazaar? Give us your endpoint URL; we fetch your 402 envelope, run the exact SDK validation and extraction functions the CDP facilitator runs, check catalog presence, and return per-check pass/fail with concrete fix hints — including the undocumented requirement that a buyer must echo your bazaar extension into the settle payload. Deterministic, no LLM.

x402 endpoint reliability pre-flight: factual service-delivery measurements of a target x402 endpoint before an agent pays it — reachability/uptime rate, valid-402 rate, response latency (p50/p95/p99), last status, and sampled paid delivery verification. Facts only (no trust score, no 'scam' label). Check whether an endpoint is live and delivers before spending on it.

https://keyronne.com/api/json-repair

Repair malformed JSON text into valid parsed JSON: markdown code fences, single quotes, smart quotes, unquoted keys, trailing commas, comments, Python literals (True/None), raw newlines in strings, and truncated output (auto-closes strings, arrays and objects). Returns the parsed value plus a log of every repair applied. Built for LLM output that almost parses. POST a JSON body like: {"text":"```json\n{name: 'Ada', age: 36, tags: ['x',], active: True"}

https://netintel.dev/web/extract

Extract article / main content from any URL or PDF to clean, LLM-ready Markdown (web scraper / reader / html-to-markdown) — strips scripts, nav, ads, and boilerplate while preserving headings, links, lists, tables, code blocks, and blockquotes; extracts the text layer from PDFs. Returns Markdown body, title, word count, and a quality grade so agents can read articles and documents without a browser or paid scraping service.

https://2s.io/api/law/cfr-section

Fetch the authoritative text of any section of the US Code of Federal Regulations by title and section number — for example title 12, section 1026.43 returns Regulation Z’s ability-to-repay standards. Returns the canonical citation, section heading, full plain text, Federal Register source credit, the as-of date, and a link to the official eCFR page. An optional date parameter (YYYY-MM-DD) retrieves the historical text in force on that date, back to 2017. Data from the Electronic Code of Federal Regulations (US GPO / Office of the Federal Register), public domain, updated daily — verify regulatory citations against the authoritative source instead of relying on model memory.

https://2s.io/api/business/naics

Look up or search NAICS 2022 industry classification codes (US Census Bureau, public domain). Pass `code` for an exact NAICS code — 2–6 digits or a combined sector like 31-33 — and get its official title, hierarchy path, full official description, activity index terms, and direct child codes. Or pass `query` for free-text search (e.g. 'software publishers', 'coffee shop') over titles plus the official ~20k-entry activity index → ranked candidate codes, optionally filtered by `level` (2=sector … 6=national industry). Ground truth for industry coding in KYC, business registration, government filings, and ERP vendor/customer setup.

https://2s.io/api/law/usc-section

Fetch the authoritative current text of any United States Code section by title and section number — for example title 17, section 107 returns the fair-use statute. Returns the canonical citation, heading, hierarchy context (title/chapter), full statutory plain text, the Statutes-at-Large source credit, and a link to the official OLRC page; set includeNotes=true to also get editorial notes (amendment history, effective dates). Hyphenated and lettered sections like 1395w-4 or 78j work. Data from the Office of the Law Revision Counsel current ("prelim") edition, public domain — verify statutory citations against the authoritative source instead of relying on model memory. For federal regulations see /api/law/cfr-section; for case law see /api/law/case-verify.

https://api.invoket.com/weather/forecast/daily

Before your agent plans a multi-day operation — logistics, construction, an event, crop work: a day-by-day forecast for any GPS point or city, with daily minimum and maximum 2 m temperature, total precipitation and peak 10 m wind per UTC calendar day, from today to the end of the NOAA GFS window (~16 days). Each day names the model that served it and carries a coverage flag.

https://http-status-checker.underscoredone.com/check

Give this API a list of up to 10 web addresses and it will visit each one to tell you whether it is working, broken, or redirecting visitors somewhere else. You get back the exact status number (like 200 for OK, 404 for not found, 500 for server error), whether the address redirects, and where it redirects to. Great for finding broken links, verifying website migrations, and running quick SEO audits without writing any code.

https://imagcon.app/routes/x402/validate

Test any x402 endpoint with a REAL signed payment from a fresh unfunded wallet — no funds can move. Returns the facilitator's verdict (healthy / broken / payment-ignored), decoded challenge, lint checks for silent payment-killers like over-long resource descriptions, and a 402index discovery report. Config validators check your paperwork; this reports what the facilitator actually said. Run it from CI after every deploy.

https://port-scanner.underscoredone.com/scan

Give this API a hostname or IP address and it will try connecting to each port in your requested range. For every port that answers, it tells you whether it is open or blocked, which service is likely running there (like a web server or SSH), and what software version was detected. This saves you from installing network tools, parsing messy command-line output, or writing socket loops yourself. Only scan hosts you own or have permission to scan — this tool does not check that for you.

BNB (BNB) price direction forecast. Kronos-base (60-path Monte-Carlo) ML model, cached ~20 min — switched from the composite heuristic 2026-07-10. Early measured record under this model: 52.6% directional over 78 scored forecasts. Prior composite record (42.9%/n147) retained at /api/stats. Falls back to the composite heuristic if the cache is briefly stale. Pay-per-call via x402 on Base USDC. Live scored track record at /api/stats — not a backtest.

https://api.cueframe.ai/v1/media/import

Import media into the project from a public https URL — the server fetches and mirrors the bytes (SSRF-filtered), then processes it (transcode + transcribe). Async: returns a media id that flips to ready when the mirror and processing finish; poll GET /media/:id or use a media.completed webhook.
