FabTally Chain — MCP server

On-chain monitoring reads an AI agent or dev polls per-call. Fronts the Chain HTTP API at https://chain.fabtally.com. Holds no private key.

Tools (all paid; a call with no payment returns the decoded x402 402 challenge)

Tool	Price	What it does
`ens_expiry`	$0.001	Resolve an ENS `.eth` / Basename `.base.eth` name's registration expiry on-chain — expiry date, days-left, 90-day grace status, release date, current owner. Args: `name`.
`gas`	$0.001	Current gas for a chain via public RPC — base fee + suggested priority + max fee (gwei) at the latest block; optional at/below-threshold boolean. Args: `chain`, `below_gwei?`.
`token_unlocks`	$0.003	Next token vesting/unlock event(s) from DefiLlama's public emissions data — date, amount, % of max supply. Cleanly says so when there's no public schedule. Args: `token` (symbol/name/address), `chain?`.
`oracle_health`	$0.003	Chainlink price-feed health — last-update age, latest answer, round monotonicity, stale flag vs heartbeat, optional deviation vs a reference. Args: `feed_address`, `chain`, `heartbeat_seconds?`, `reference?`.

Every tool also accepts an optional x_payment (base64 x402 payload) that is forwarded as the X-PAYMENT header to settle the call and return the real result. Humans can instead prepay by card and use an X-FabTally-Key credit key against the HTTP API.
