dYdX v4 chain-state history, deterministic and block-stamped. Answers "what was dYdX open interest and funding index for this market over time". Hourly samples read from public blockchain state (never the geo-restricted indexer): open interest in units and USD (archived oracle price), cumulative funding_index with per-interval deltas, block height and available_at per row. Archive coverage is honestly disclosed via history_since. No LLM, no 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.

Compared: listed price, settlement rail and input compatibility. Not measured yet: latency, reliability, result quality, and provider terms such as rate limits, jurisdiction and licensing.
