How this service works
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.
Output
An array of hourly rows for the requested dYdX v4 market, each containing: open interest in native units, open interest in USD (using archived oracle price), cumulative funding_index, per-interval funding index delta, block height, and available_at timestamp. Also includes a history_since field indicating the earliest available coverage date.
Example use cases
Example prompt
“Pull me the hourly dYdX v4 chain-state history for ETH-USD — I want to see open interest in both units and USD plus the cumulative funding index with per-interval deltas going back as far as the archive covers.”
Technical details
Endpoint
GEThttps://cryptopulse.theaslangroupllc.com/api/dydx-historyWhen to prefer
Choose this endpoint when you need deterministic, block-stamped historical open interest and funding index data sourced directly from dYdX v4 chain state — especially when geo-restricted indexer access is a problem, or when you need verifiable on-chain provenance. Ideal for backtesting funding strategies, auditing open interest trends, or building analytics that require tamper-evident blockchain-sourced data rather than off-chain indexer estimates.
Side effects
- Unknown or unsupported market symbol returns an error or empty result
- Requested time range predates history_since coverage, returning partial or no data
- Blockchain node unavailability causes delayed or failed state reads
- Rate limiting or x402 payment failure returns 402 with payment details
- Invalid parameter format returns 400 bad request
