Multi-chain gas price oracle: current base fee plus priority-fee tiers for EVM chains. POST /v1/gas with {chain_id} and get the base fee and slow/standard/fast tiers as one JSON object. Deterministic per read instant. Pay per request in USDC; no account, no API key.

price-ascending: candidates are ordered by the listed price of the operation, with no managed-first preference applied. Unlike /v1/apis, this surface does not rank Apiosk-settled listings above federated ones — a comparison that reorders on commercial grounds is not a comparison. Pass sort=managed_first for the catalog's ordering.
