Where a token earns the most: DefiLlama's yield pools filtered by chain (default Base), token symbol (USDC, ETH…), stablecoin-only and minimum TVL (default $1M), sorted by APY or TVL - with base vs reward APY, the 30-day mean, IL risk and a link per pool. Outliers are excluded unless asked. Pay-per-call via x402.

ETH balance of any address on Base (wei + ETH). Pay-per-call via x402. An empty body is answered for the wallet that pays on Base (the payment's signer); send {"address":"0x…"} for any other address.

USDC balance of any address on Base — the x402 settlement asset (atomic + USDC). Pay-per-call via x402. An empty body is answered for the wallet that pays on Base (the payment's signer); send {"address":"0x…"} for any other address.

Hyperliquid perpetuals in one call: mark/oracle/mid price, 24h change, funding rate and its annualised APR, open interest in coins and USD, 24h volume, max leverage - plus the same coin's next funding on Binance and Bybit for cross-venue comparison. Name a coin (BTC, ETH, SOL, HYPE…) or send {} for the most-traded markets. Pay-per-call via x402.

The x402 market by seller over the last 30 days: estimated revenue, paid calls, paying wallets, calls per payer, median price, networks and each seller's top resource - from Coinbase's public x402 discovery index, read hourly. Rank by revenue, calls or payers; filter by keyword and network; a payer floor (default 3) drops lone testers. Send {} for the top 20 by revenue. Pay-per-call via x402.

Transaction status on Base — success/failed, block, confirmations, gas, from/to. A pending/unknown tx returns 404 (not charged). Pay-per-call via x402. An empty body is answered for the latest transaction on Base (read live from the chain head); send {"txHash":"0x…"} for any other transaction.

Tokens that just appeared or are being promoted right now - DexScreener's new token profiles, community takeovers and paid boosts - each with price, liquidity, 1h/24h volume, buys/sells, price change, market cap and pair age from its most liquid pair. Filter by chain (default every chain), list and minimum liquidity ($10k default); sort by volume, liquidity, change or newest. Send {} for every chain. A boost is paid promotion. Pay-per-call via x402.

Resolve an ENS name or Basename to its address (vitalik.eth, jesse.base.eth), or an address to its primary name - verified to resolve back - with the profile records the owner published: url, X/Twitter, GitHub, description, avatar. Read from Ethereum mainnet through the ENS Universal Resolver; off-chain gateways go through our SSRF guard. ASCII names. Send {} for the published example. A name with no address is not charged. Pay-per-call via x402.

Base, Ethereum and five more chains. Send {} for USDC on Base. Pay-per-call via x402. An empty body is answered for USDC on Base (the x402 settlement asset); send {"token":"0x…"} for any other token.
