Decimals of an ERC20 token — Genesis402 / UnyKorn Operator Network

Extract a page's machine-readable self-description in one call: every JSON-LD block (schema.org), OpenGraph and Twitter Card metadata, canonical URL, title, meta description, H1, hreflang alternates and RSS/Atom feed links — parsed server-side into clean JSON. Where text extraction gives you prose, this gives you structured facts.

Returns the visible order book of Binance, Coinbase, Kraken, OKX or Bybit for one BASE/QUOTE pair. Levels come as [price, size] with bids descending and asks ascending. depth[] states how much turnover sits within 0.5, 1 and 2 percent of the mid per side, in the quote currency, and additionally as depth_usd where the quote is a US dollar unit. group_bps folds levels into price bands whose price is the size weighted average of the band, for agents that do not want a thousand rows. The exchange up

Historical rank overview API - a monthly time series of a domain's Google organic and paid visibility: ranked keyword count, estimated traffic (ETV), traffic cost and position buckets (pos1/top3/top10/top100) for each month. For tracking a site's SEO trajectory, spotting traffic drops/recoveries and competitor trend analysis. Unknown domain returns an empty series.

Node.js hosting: ship the Node app you built locally, unchanged — full server runtime on Cloud Run with a dedicated Postgres. Native modules OK. App reads DATABASE_URL + listens on PORT. Filesystem is writable but ephemeral (scale-to-zero) — keep durable state in Postgres. Durable /data file storage (1 GiB included).

Historical per-venue funding rates for one crypto perpetual, aggregated 1h/4h/1d, across tracked CEX and DEX venues — the timeseries a funding-arb backtest needs. Up to 30-day windows (30-day retention). Edge-isolated: raw rates only, no spread or signal logic.

One-call market snapshot for one crypto perpetual across every tracked venue — funding rate, annualized carry with contango/backwardation structure, open interest, 24h volume and mark price in a single response. Bundles funding/carry/open-interest/volume-24h so an agent makes one paid call instead of four.

Cross-venue funding-rate spread for one crypto perpetual — the highest- and lowest-paying venues and the spread in bps, across major CEX and DEX venues (Binance, Bybit, OKX, Hyperliquid …). `spread_bps` is the RAW rate difference, the same quantity and name as on `/v1/perp/arbitrage/funding`; `normalized_spread_8h_bps` scales both legs to 8h, the comparable one, since venues quote on 1h/4h/8h. Leg intervals ship with the row; normalized is null when a schedule is unknown, never defaulted.

Per-venue basis for one crypto perpetual — mark versus index price, basis_bps = (mark−index)/index×10000, and contango/backwardation structure, across tracked CEX and DEX venues. Every venue has an index except Crypto.com, Variational and dYdX; dYdX publishes one oracle price, which is its mark. `venues_without_index` names the ones missing. Each venue also carries liquidity_state (live/dead/unknown), and a market with no trading is flagged unreliable however clean its basis looks.

Live US mortgage and macro rate snapshot. Returns 30-year and 15-year fixed mortgage rates, the prime rate, the fed funds rate, and CPI year-over-year, each with its as-of date.

Funding-arb SIGNAL for crypto perpetuals — the cross-venue funding spread per pair, set against public round-trip taker fees, with periods-to-breakeven, ranked by the 8h-normalized spread. Liquidity is not assessed: depth sizing was withdrawn on 2026-09-16, so check the books before sizing. A derived outcome, not a profit forecast.

Depth quote for one crypto perp on ONE named venue: best bid/ask, depth per side, and est_slippage_for_size_usd_bps — the cost of filling size_usd here, in BASIS POINTS over the mid, not dollars. On a book deep enough to fill at the touch it equals half the spread and is the same for $1K/$5K/$10K; on a thinner book it grows with size. Equal values across sizes mean the book covers you, not that size_usd was ignored. All venues: /v1/orderbook/multi-venue-slippage. $10K cap per DIS-022.
