ENI Premium Data Feed - Real-time market data and analytics

Is your x402 service still listed? The Bazaar removes resources that go without settlement, and no one tells you. We keep a daily snapshot of the whole catalog since June, so we can show whether your domain is present today, how its resource count moved day by day, and how long since each resource was last paid for. In our latest scan 620 of 2,147 domains are no longer present. Measured from our o

Curated majors (ETH, WETH, USDC, DAI, cbETH, cbBTC, BTC) are priced from Chainlink's own Data Feed aggregator contracts on Base; any other Base ERC-20 address is priced from its deepest discoverable Uniswap V3 pool against USDC (with a liquidity read and a low-liquidity flag), or a clean unsupported-to

Groups managed news feeds into events when an agent needs a compact news briefing. Supply topic, language, time window and result limit using the published schema.

Web scraping API for AI agents: read any live web page as clean markdown, text or HTML. Renders JavaScript in our own headless browser, then strips navigation, ads and boilerplate. Use it when a plain HTTP GET returns empty or garbled HTML: single-page apps, dynamic feeds, or content that only appears after scripts run. Also returns the page's HTTP status. Page text is flagged untrusted so an agen

Compound a list of period returns into a total growth factor. Call when multi-period performance rollups from return series you already have. Returns compounded factor and total return as deterministic JSON for $0.001 USDC via x402 on Base. First-party local math only—no RPC, live market feed, API keys, storage, or mediagen.

XML tier (deterministic, no LLM): verifies a claimed value lives at a named path in a public XML document, by independent double re-fetch. Use it for feeds and sitemaps; for JSON use /verify-json, for HTML use /verify. Paths address elements and @attributes (urlset.url[0].loc). String-exact; ambiguous or volatile values return unverifiable, never a guess. First 100 checks per client are free: rese

Strait of Hormuz per-vessel intelligence: the live-AIS vessel manifest (MMSI-keyed, flag derived from the MMSI MID), the OFAC-sanctioned vessels the AIS feed lists in the Persian Gulf window (last fix up to 12 hours old, aged per row by fixAgeMin) with program detail, per-vessel risk bands, latest raw AIS positions, the top AIS-dark hulls with the full dark count alongside, and OFAC + UK sanctions
