Crypto & Blockchain

Day's biggest gainers and losers screened from the entire market, live from Yahoo Finance. Each mover includes ticker, company name, current price, intraday change amount and %, and volume — the market context every trader needs. Not ticker-specific. Supports optional limit per list (default 10, max 25). $0.01/call.

Prediction market odds in one call: keyword search across Polymarket AND Kalshi simultaneously -- no other market-data API aggregates both -- returning each match's live, real-money-backed outcome probabilities, volume, and close date. Crowd-sourced forecasts for Fed decisions, elections, and macro events often beat polls and analyst surveys; pairs naturally with this API's own FOMC/economic calendar. Not ticker-specific. $0.025/call.

Live gas conditions for an EVM chain: current gas price, the latest block's base fee (EIP-1559) and the suggested max priority fee — all in both wei and gwei. Ground truth an agent can't compute. Reads live on-chain data with automatic endpoint fallback.

Live ERC-20 token balance held by a wallet: calls `balanceOf(address)` on the token contract and returns the raw balance plus a decimal-formatted amount (using the token's own decimals) with its symbol. Distinct from `address` (native ETH balance) and `token` (contract metadata). Reads live on-chain data with automatic endpoint fallback.

Live L2 order book for a crypto perp market: aggregated bids and asks with price, size and resting-order count per level, plus the best bid/ask spread, spread % and mid price. Real-time market-depth snapshot for a coin (BTC, ETH, SOL, and more); pass `depth` for how many price levels per side. Data source: Hyperliquid (dYdX fallback).

Live perpetual-futures funding rates per market — each market's funding rate as hourly, the standard 8-hour figure and annualized %, alongside mark price and open interest. Ranked by the most extreme (|annualized|) funding by default; pass `coins` to get the funding rate for a specific market (e.g. ["BTC","ETH"]). Real-time crypto perp funding rate feed. Data source: Hyperliquid (dYdX fallback).

Crypto perpetual-futures data from on-chain perp DEXs: per market the funding rate (hourly + annualized %), open interest (USD and base units), mark & oracle price, 24h volume and 24h price change. Ranked by open interest; filter by `coins` or `limit`. Data source: Hyperliquid (dYdX fallback).

Crypto categories & sectors ranked by total value locked (USD): each DeFi narrative (e.g. Dexes, Lending, Liquid Staking, Restaking, RWA) with its aggregate TVL, protocol count and share of total DeFi TVL. A map of where capital sits across sectors. Centralised-exchange reserves are excluded.

Compute network details of a CIDR block — network & broadcast address, usable host range, total and usable address counts. Works for IPv4 and IPv6 (counts returned as strings for large IPv6 blocks). Honours RFC 3021 for /31.

Signed multi-chain OFAC SDN address screening (USDC on Base or Solana)

Pre-transaction risk screening for a domain, company or email domain: DNS resolution, MX presence, SSL validity/expiry, domain age via RDAP, website reachability. Returns risk score 0–100, risk level, per-check results and evidence. Run it before an agent pays, emails or integrates with an unknown party.

A structured token/contract risk report for a Base contract: a normalized risk score, a pass/warn/fail checklist (bytecode present, sanctions, verified source, ownership, holder concentration) and a single verdict. $0.05.

Crypto staking rewards: live staking APY and TVL for liquid-staking and restaking protocols (Lido, Rocket Pool, ether.fi, Jito, Binance, …), ranked by size. Filter by asset (e.g. ETH, SOL), chain or protocol. Data source: DefiLlama.

Crypto price history as OHLC candles from on-chain perp DEXs: open/high/low/close, base volume and trade count per interval (1m, 5m, 15m, 1h, 4h, 1d) for a coin (BTC, ETH, SOL, and more). Returns up to 500 candles, oldest first. Data source: Hyperliquid (dYdX fallback).

DeFi market overview: total value locked (USD) across all chains, the chain count, and the top chains by TVL with each chain's TVL dominance. This is DeFi TVL — not total crypto market cap.

24h DEX trading volume by chain and protocol

Official FX rates — all eight pairs. All supported African pairs vs USD in one payload.

Statically analyse a Model Context Protocol (MCP) server manifest for security risks. Tool descriptions enter the model context, a prime prompt-injection vector. Deterministic and offline (inline manifest). Flags dangerous capabilities (command/code execution, filesystem, credential and network access), injection patterns, hidden unicode and unconstrained parameters. Returns severity-ranked findings and a 0-100 score.
