## Tools
- ens_expiry (ENS / Basename expiry lookup (paid $0.001)) - PAID $0.001 (x402, USDC on Base). Resolve an ENS .eth or Basename .base.eth name's registration expiry ON-CHAIN (public RPC). Returns expiry date, days-left, whether it's in the 90-day grace period, the release date it becomes registrable again, and the current owner. Read-only, descriptive. Args: name. Without payment returns the x402 challenge; pass x_payment to settle. Endpoint: https://chain.fabtally.com/mcp
- gas (Current gas for a chain (paid $0.001)) - PAID $0.001 (x402, USDC on Base). Current gas for a chain via public RPC: base fee + suggested priority + suggested max fee (gwei) at the latest block. If below_gwei is set, also returns whether the base fee is at/below your threshold right now. Read-only. Args: chain (ethereum|base|arbitrum|polygon|bsc|optimism), below_gwei (optional). Without payment returns the x402 challenge; pass x_payment to settle. Endpoint: https://chain.fabtally.com/mcp
- token_unlocks (Next token vesting/unlock event(s) (paid $0.003)) - PAID $0.003 (x402, USDC on Base). Next token vesting/unlock event(s) from DefiLlama's PUBLIC emissions dataset: upcoming unlock date(s), token amount, and % of max supply, with a human description. Cleanly says so when a token has no public unlock schedule. Read-only, descriptive — NOT a price signal. Args: token (symbol, protocol name, or contract address), chain (optional, for address lookup). Without payment returns the x402 challenge; pass x_payment to settle. Endpoint: https://chain.fabtally.com/mcp
- oracle_health (Chainlink price-feed health (paid $0.003)) - PAID $0.003 (x402, USDC on Base). Chainlink price-feed health via public RPC: last-update age, latest answer (scaled by decimals), round monotonicity (is the answer current?), a stale flag vs the heartbeat, optional deviation vs a reference price, and per-factor flags. Read-only, descriptive. Args: feed_address, chain, heartbeat_seconds (optional), reference (optional). Without payment returns the x402 challenge; pass x_payment. Endpoint: https://chain.fabtally.com/mcp
