Cheap poll: has this proposal's state changed since you last looked? You pass the state this route or GET /proposal-status gave you last time; it reads the Governor's current state and compares. Call it with no state to get a baseline. One contract read, which is why it is cheap; when it reports changed, buy GET /proposal-status for the new state, its execution_eta and what that means on this contract family. Terminal states (executed, defeated, canceled, expired) never change again -- the response says so explicitly and tells you to stop polling, because charging for a poll that can only ever answer 'unchanged' would be selling nothing. Required: dao and proposal_id. Optional: state.

The fate of ONE already-known proposal after the vote: executed / queued in Timelock / expired / canceled. A follow-on to /dao-proposals — that route shows whether a vote is active or has passed; this one shows whether a passed vote actually reached real execution (the same class of off-chain-tracker blind spot as the Arbitrum/48M ARB case, just one step later, after the vote). Required query parameters: dao (ENS, Arbitrum, Uniswap, Compound) and proposal_id. Optimism is not yet on this list (2026-08-11 incident — its Agora fork emits ProposalCreated with a different event structure, discovery for it not yet decoded; already supported in GET /dao-proposals).

single-fact lei lookup. Answers from a bundled CC0 subset of GLEIF Level 1 data, vintage 2026-08-15: 20000 ACTIVE, ISSUED records cut in ascending LEI order from a 1953582-record pool. The range is not dense, so a valid LEI can sort inside it and still be absent; absence here is absence from THIS snapshot, never from the Global LEI System. An unknown or malformed LEI is refused by name, never guessed. The full bound is stated free in the discovery declaration on this challenge.
