Look up an on-chain transaction by hash. Given a chain and a transaction hash returns sender, recipient, value (wei + ETH), nonce, block number, status (success/reverted), gas used, effective gas price, log count and any created contract. For explorers, payment-verification, settlement-checking and monitoring agents.

Check transaction status on Base or Solana. Returns confirmed, status, block/slot, gas, err.

Read USDC or native token balance for an address on Base or Solana. Body: {chain, address, token?}.

Current Base mainnet gas price with slow/standard/fast tiers in gwei.

Current Ethereum gas price (wei + gwei)

Check an outbound payout immediately before authorization to catch changed destinations, duplicate payments, amount or currency drift, and malformed payment details.

Activate a newly created project so its site goes live, paying per day of hosting (1-730 days via the days query parameter). Call this after the first deployment is queued; only the owner wallet bound at creation can pay.

Crypto Fear & Greed Index (0-100) with classification

Detailed data for a single token (by contract address)

On-chain token price by contract address (DEX / DeFi). Given a chain (e.g. ethereum, base, bsc, polygon, arbitrum, solana) and one or more token contract addresses, returns current USD price, market cap, 24h volume, 24h change % and last-updated timestamp for each. For DeFi agents, on-chain price feeds, DEX token lookups and portfolio valuation of long-tail or newly listed tokens.

Historical crypto price, market cap and volume time series. Given a coin id or ticker and a window of days (1-365) returns aligned price, market-cap and total-volume points with ISO timestamps — finer-grained than OHLC candles. For charting, market-cap trend analysis, volume studies, backtesting and portfolio agents.

Crypto derivatives, perpetual futures and funding rates. Returns active derivative contracts with market/exchange, symbol, index, price, 24h change %, funding rate, open interest and 24h volume. For funding-rate arbitrage, perp market monitoring, basis-trading and derivatives-analytics agents.

Crypto market sectors ranked by market cap. Returns categories (e.g. DeFi, Layer 2, meme coins, AI, real-world assets, stablecoins) with total market cap, 24h market-cap change %, 24h volume, top coins and last-updated timestamp. For sector rotation, narrative tracking, market-structure analysis and thematic screening agents.

ERC-20 token metadata and total supply by contract. Given a chain and a token contract address returns name, symbol, decimals and total supply (raw + decimal), read live on-chain. For token explorers, due-diligence, supply-tracking and DeFi agents.

On-chain ERC-20 token balance for a wallet. Given a chain, a wallet address and a token contract address returns the token balance (exact raw units + decimal), with token name, symbol and decimals, read live from the chain. For wallet trackers, DeFi portfolio valuation, airdrop checks and treasury-monitoring agents.

Fetch an EVM block (latest or by number). Given a chain and an optional block number returns block number, hash, parent hash, timestamp, transaction count, gas used/limit, base fee and miner. Omit the number for the current block height. For indexers, chain-tip monitoring, finality-tracking and block-explorer agents.

DEX liquidity and volume observations for tracked Base tokens

Full AI-readiness audit of any website: 47 checks across 7 categories (agent permissions, content discoverability, structured data, API/MCP infrastructure, pricing transparency, documentation, agent commerce). Returns 0-100 score, grade, per-check pass/fail and prioritized fixes. Use before recommending, buying from, or integrating with a site.

Perp funding rates across Binance/Bybit/Hyperliquid, normalized to 8h-equivalent, plus cross-exchange divergence (annualized bps, top20 arbitrage signal). GET /funding-rates or /funding-rates?symbol=BTC → JSON. Free-source, 60s cache.

Every distinct Binance/Bybit/Hyperliquid exchange-pair funding-rate spread per symbol (not just the single highest-vs-lowest pair), sorted by annualized bps divergence descending, with short(high-funding venue)/long(low-funding venue) direction per pair. GET /funding-rate-arb (top20 across all symbols) or /funding-rate-arb?symbol=BTC (all pairs for that symbol) → JSON. Pure arithmetic on the same cached data as /funding-rates, $0 marginal cost, 60s cache.
