x402-mcp.onrender.com/base/finality-check

Base mainnet transaction finality check: given a tx hash, classifies it as not_found, pending, unsafe (sequencer-confirmed only), safe (L1-attested), or finalized (L1-finalized) -- read directly from the node's own safe/finalized block tags, not a modeled reorg probability. Input: tx hash. Output: JSON.
