Gamma Exposure (GEX) and max-pain options tool for BTC and ETH from the Deribit public API. Returns an aggregate GEX strike ladder (dealer-convention net gamma per strike), gamma flip level (zero-cumulative-GEX strike), spot regime above or below flip, max-pain strikes for upcoming weekly and monthly expiries, an expected-move cone (ATM-IV-derived 1-sigma, front expiry), and a heuristic pin-risk score. 15-minute in-memory cache. $0.04 USDC via x402.

Get historical weather and climate for many locations/dates at once (ERA5 reanalysis): 2 m temperature, total precipitation and 10 m wind for many point/date pairs in one call (one x402 settlement), for dates within the rolling ~5-year ERA5 window, decoded from GRIB. Each item takes lat+lon or a city name (alias location, optional country). Per-item coverage flags partial results: an item out of window, off-grid or with an unknown city returns coverage.complete=false instead of failing the batch. No account, no key. Priced per query.

Check whether a list of legal citations is still in force (contract review, due diligence): up to 50 article references (French LEGI codes/statutes or EU CELEX acts) at a given date in a single x402 settlement. Consolidated text, status and validity dates per item. Covers the 12 major French codes (civil, labor, commercial, penal, tax/CGI, social-security, monetary & financial, environmental, IP, insurance, consumer) plus the Data Protection Act, and key EU acts (GDPR, eIDAS, e-Commerce, DSM copyright, DSA, DMA, AI Act, MiCA, NIS2). No account, no key.

Get climate-event indices for any location over a date range within the rolling ~5-year ERA5 window (reanalysis): frost and summer days, tropical nights, dry spells, heavy-rain days, max one-day rainfall, total precipitation and peak gust — parametric-insurance triggers computed from true daily Tmin/Tmax, decoded from GRIB. Also accepts city=<name> (alias location=, optional country= ISO 3166 alpha-2) instead of lat/lon, resolved via the embedded GeoNames gazetteer (exact match, most populous wins) and echoed back as data.location. No account, no key, pay per call.

Track how a French or EU law changed over time: get the version timeline of an article (French LEGI code/statute or EU CELEX/ELI act) with each version's status (in force, repealed, superseded or deferred) and validity dates, to detect exactly when it changed. Covers the 12 major French codes (civil, labor, commercial, penal, tax/CGI, social-security, monetary & financial, environmental, IP, insurance, consumer) plus the Data Protection Act, and key EU acts (GDPR, eIDAS, e-Commerce, DSM copyright, DSA, DMA, AI Act, MiCA, NIS2). No account, no key, pay per call.

See exactly what changed in a French or EU law between two dates: resolves the version in force at each date and returns a structured diff of the consolidated text — word-level segments plus a git-style unified patch — with the version metadata of both endpoints. Covers the 12 major French codes (civil, labor, commercial, penal, tax/CGI, social-security, monetary & financial, environmental, IP, insurance, consumer) plus the Data Protection Act, and key EU acts (GDPR, eIDAS, e-Commerce, DSM copyright, DSA, DMA, AI Act, MiCA, NIS2). No account, no key, pay per call.

Get heating, cooling and growing degree-days for any location over a date range within the rolling ~5-year ERA5 window (reanalysis): energy-demand and crop-growth signals computed from daily mean temperature, decoded from GRIB. Also accepts city=<name> (alias location=, optional country= ISO 3166 alpha-2) instead of lat/lon, resolved via the embedded GeoNames gazetteer (exact match, most populous wins) and echoed back as data.location. No account, no key, pay per call.

Check whether an EU law is in force at a given date: consolidated text, status and validity dates of an EU act or article by CELEX/ELI identifier, from EUR-Lex. Covers key EU digital & financial acts: GDPR, eIDAS, e-Commerce, DSM copyright, DSA, DMA, AI Act, MiCA and NIS2. No account, no key, pay per call.

Compare a list of legal citations across two dates each: get a structured diff of the consolidated text (word-level segments plus a unified patch) for up to 50 French (LEGI) or EU (CELEX/ELI) article references in a single x402 settlement. Covers the 12 major French codes (civil, labor, commercial, penal, tax/CGI, social-security, monetary & financial, environmental, IP, insurance, consumer) plus the Data Protection Act, and key EU acts (GDPR, eIDAS, e-Commerce, DSM copyright, DSA, DMA, AI Act, MiCA, NIS2). No account, no key.

Monitor a portfolio of legal citations over time: get the version timeline (status and validity dates) of up to 100 French (LEGI) or EU (CELEX/ELI) article references in a single x402 settlement, to detect when any of them last changed. Covers the 12 major French codes (civil, labor, commercial, penal, tax/CGI, social-security, monetary & financial, environmental, IP, insurance, consumer) plus the Data Protection Act, and key EU acts (GDPR, eIDAS, e-Commerce, DSM copyright, DSA, DMA, AI Act, MiCA, NIS2).

Get period climate summaries for any location over a date range within the rolling ~5-year ERA5 window (reanalysis): mean, min and max temperature, total precipitation and mean wind at any GPS point, decoded from GRIB. Pass location=<place name> (alias city=, optional country= ISO 3166 alpha-2 filter) instead of lat/lon: resolved against the embedded GeoNames cities500 gazetteer (exact name match, most populous match wins — no fuzzy matching), echoed back as data.location. No account, no key, pay per call.
