The latest Sentinel-2 satellite images of any point on Earth - date, cloud cover, tile, a JPEG preview link and the full true-colour image (10 m per pixel, Cloud-Optimized GeoTIFF) - newest first, under a cloud limit (default 30%) within a look-back window (default 60 days). Copernicus open data via Earth Search; the required attribution is included. Send {} for the published example point. No scene is not charged. Pay-per-call via x402.

Perplexity — web search over Perplexity's own retrieval index, the one behind its answer engine, returning ranked results with snippets plus `date` and `last_updated` per hit. Pass `query`; optional `max_results` (1-10), `search_recency_filter` (hour|day|week|month|year), `country` (ISO-2), `max_tokens_per_page` (trim the excerpt), `search_domain_filter` (array of domains to include, or `-domain.com` to exclude). The freshness signal is the differentiator — results carry when the page was last …

Firecrawl — Extract structured data from URLs using a schema.

Everything about a domain in one call: registrar, creation and expiry dates and age from the registry's own RDAP, live DNS (A/AAAA/MX/NS), email authentication (SPF, DMARC policy) and the TLS certificate it serves (issuer, validity, days left, whether it covers the name). Pay-per-call via x402. An empty body is answered for the published example domain (example.com); send {"domain":"…"} for any other domain.

Watchlist renewal: extend an existing company monitoring watchlist by 30, 90 or 365 days (?duree=, default 30, any duration whatever the original) of daily surveillance against official sources — $0.05 / $0.135 / $0.50 per target. The cibles parameter must repeat the exact watched targets: it is what the quote is computed from. Possible until 7 days after expiry, then the watch is purged. No refund, no pro rata.

List the merchants behind the catalog. Filter by name or domain search, by country, or by product count, and page through the results.

Enriched context for a single match: the teams, venue, status, and surrounding tournament state, addressable by event, event URN, or team and opponent on a date.

Kadec0 — 29 public-data endpoints over x402: academic papers, CVE, FDA/recalls, SEC EDGAR, congress trades, USGS quakes, permits, whois/domain/DNS, geocode, weather, nutrition, HackerNews/StackOverflow, DeFi TVL/yields/gas. GET { endpoint, ...query }. 1-11¢ caps. See research + onchain-data knowledge docs.

Product reviews for a company's offerings (ratings, star distribution, pros/cons, reviewer metadata) by domain or Akta uuid. Competitive teardown and win/loss signal. Pass { company: 'tesla.com' }; optional `products` narrows to specific product ids.

Strale — 191 compliance/KYB/company-data checks over x402: sanctions/PEP/AML/adverse-media screening, company registries (UK/US/EU/JP/BR & more), email & domain trust, trade/customs/shipping, web3 due-diligence /solutions/*. POST { endpoint, ...input }. Caps 3¢–$1.19; user pays actual settle. See compliance-data knowledge doc or vaaya/discover.

Linkup — DEEP agentic search: iterative multi-query retrieval for hard or multi-hop questions where one-pass search misses. Same params as linkup/search (`q` + outputType/dates/domain filters). Slower (tens of seconds) and 5× the price — escalate here only after linkup/search or exa/search come back thin. For full multi-step research reports, parallel/task (10-30¢) is the bigger rung.

Tavily — extract clean page content (JS handled) from up to 5 URLs you already have, in one 1¢ call. Pass `urls` (array, ≤5); optional `format` (markdown default | text). For bigger batches make multiple calls. Alternative to exa/contents (0.1¢/url, no JS) and firecrawl/scrape (1¢/url, full rendering).

Get flights from one airport to another specific destination airport

ScrapingAnt — Scrape a URL and return LLM-ready markdown (rendered in headless Chrome, then converted). Pass `url`; optional browser/wait_for_selector/proxy_country/timeout knobs. Returns `{ url, markdown }`. Alternative to crw/scrape or firecrawl/scrape when you want ScrapingAnt's proxy pool behind the fetch.

Modal — Create a sandboxed compute environment (CPU by default, 300s timeout). Pass `gpu` (T4 | L4 | A10G | A100 | H100) for GPU workloads like model inference.

Complete DNS inspection in one call over DNS-over-HTTPS: A, AAAA, MX, TXT, NS, CNAME, SOA and CAA records with TTLs — plus a derived email posture analysis (SPF present and policy, DMARC present and policy, MX count, overall assessment) that raw lookup tools don't do.
