DeFi protocol TVL ranking (7742+ protocols): top protocols by TVL with chain breakdown, 1d/7d change. Filter by chain or category (DeFiLlama, free, no key).

Bitcoin network statistics: price, hash rate, daily tx count, block time, total supply mined — via blockchain.info, no API key.

DeFi protocol TVL breakdown by chain, category, description, staking/borrowed TVL (DeFiLlama, free, no key). Covers 3000+ protocols.

Blockchain TVL overview — all 469+ chains ranked by total value locked with token symbol and chain ID (DeFiLlama, free, no key).

Bitcoin mempool size and unconfirmed transaction count, via mempool.space API

Look up a static chain id to network name table without live RPC — call when mapping a static chain id to a network name (no tip). Use for chain input hygiene without live RPC—adjacent to OneSource-class small chain reads, but static/local only so rights and margin stay clear. Returns deterministic machine-readable JSON for $0.003 USDC via x402 on Base. Execution is first-party, local-only, stateless, and memory-only with no paid upstream, no input retention, and no claim of live chain tip, web search, or media generation. Results are advisory; the caller owns authorization and production controls.

Executes queries against blockchain data or smart contract information.

Query Lightning Network node info by pubkey. Returns alias, capacity, channel count, and connectivity. 30 sats per request.

Returns a list of supported EVM blockchain networks and their configurations.

Returns the latest block information from the Solana blockchain.

Check if a Base address is a contract and return bytecode size for $0.001 USDC via eth_getCode.

Latest Base mainnet block header via live JSON-RPC for $0.001 USDC—number, hash, timestamp, gas.

Returns current blockchain information including chain height, difficulty, and network statistics.

Barker's cross-chain route availability for a stablecoin from a given chain (bridge/venue coverage). Use for 'bridge USDC from arbitrum', '跨链路径'.

Look up supported blockchain network metadata and chain IDs for $0.001 USDC. Static first-party registry only—no live RPC, balances, blocks, receipts, gas, or contract reads.

Lightning Faucet Node Info (50 sats)

Verified smart contract metadata on Base mainnet by address. Returns contract name, compiler version, ABI, implementation address for proxies, license, optimization runs, EVM version. AI agent contract verification, security audit, ABI lookup, Base L2 contract API.

Base block header by hash for $0.001 USDC via eth_getBlockByHash.

Inspect live bytecode and common EIP-1967 and EIP-1167 storage patterns to identify upgradeable contract proxy evidence.

Read deployed bytecode for an address and return contract-versus-EOA classification, byte size, and bytecode hash.

Retrieve a live EVM block header and a bounded list of real transaction hashes by height, tag, or block hash.

Provides access to the Polygon mainnet blockchain network for querying transactions and state data.

Provides access to the XLayer testnet blockchain network for development and testing purposes.

Bitcoin block info by height or hash. Returns hash, height, timestamp, tx count, total fees, miner pool ID, size, weight, difficulty, merkle root, version, nonce, up to 100 tx IDs. AI agent BTC block explorer API, network state analysis, mining metrics.
