DYOE Know Your Agent (KYA) — the pay-safely pre-flight before an agent sends money. ONE call vets the whole deal: is the counterparty SITE legit (scam/fraud/phishing/rug) AND is the payee WALLET safe (OFAC-sanctioned? disposable?), weighed against amount vs. policy. Returns proceed/caution/stop + reasons + a signed, verifiable attestation — one go/no-go instead of three calls. Input: ?domain=merchant.com&wallet=0x...&amount=500

DYOE Wallet Check — is this CRYPTO WALLET safe to pay? Before your agent sends funds to an address, screen it: AUTHORITATIVE OFAC sanctions check (never pay a sanctioned wallet) + on-chain footprint (empty/disposable-address red flag) + human-vouch overlay. Returns verdict (safe/caution/avoid), sanctioned flag, on-chain activity & red_flags. Counterparty trust for the address itself — the payment-safety layer for the agent economy. Input: ?address=0x...

A dated, freshly rebuilt brief on where demand is in the agent-payment economy: what builders and agents are discussing and paying for in the last 30 days (Hacker News, GitHub, Polymarket, marketplace listings), plus our own paid-endpoint call and settlement performance. Rebuilt every day at 06:00 WIB; yesterday's copy is not the product.

Daily EUR foreign-exchange reference rates (source: European Central Bank). Returns the latest ECB reference rate for any supported currency vs EUR, plus cross-rate conversion between two non-EUR currencies.

Daily market intelligence on the x402 Bazaar: index size and composition by network/scheme, USDC price distribution percentiles, real usage stats (share of resources with 30-day calls, top-20 by calls), new-listing rate, churn-risk aging, and domain concentration. Aggregated from the public CDP discovery API. Rebuilt daily by an autonomous agent.

Daily state of the x402 agent economy: observed USDC inflow, seller ranking, category demand, growth, and coverage. Reports its real observation window; concentration adjustment applied only when scan coverage supports it.

Includes each asteroid's estimated size, relative velocity, and miss distance. Sourced from NASA JPL's Near Earth Object Web Service (NeoWs).

Current U.S. EPA Air Quality Index (AQI) and pollution levels for a specific location, given latitude/longitude — use to check smog, air pollution, or whether it's safe to be outside. Sourced from the EPA AirNow program (federal/state/local/tribal agencies); covers the US, Canada, and Mexico only. Data is preliminary and unvalidated per EPA data use guidelines — not for regulatory use.

Identify the location by NOAA CO-OPS station ID, or just pass lat+lng and the nearest station is used automatically (distanceKm in the response says how far it is). Heights in feet above MLLW datum, times in GMT.

Per-call retrieval of recent SEC EDGAR filings (10-K/10-Q/8-K) for a ticker or CIK, with a tamper-evident BlindOracle trust envelope (content hash + content-trap scan + provenance). Public-domain source.

Searches the official EU open data portal and returns datasets with what decides whether they are usable: the licence, classified by whether commercial reuse is allowed and what attribution or share-alike it demands. A dataset under a non-commercial licence is marked as unusable for a paid product rather than listd as if equivalent. Each result also carries its publisher, country, last modification date, the distribution formats available and how many there are, and direct links.

Catalog of 19 synthetic datasets for AI agent training and testing — financial markets, x402 agent payment traces, MCP tool-call transcripts, healthcare claims, IoT sensor logs, and more. Each category is generated on demand and purchasable individually via /datasets/detail. Catalog access is priced at $0.035 per delivered catalog row per successful call.
