get_options_activity

Get options activity · $0.02 per call (x402, USDC) Retrieves retained options bars, flow aggregates and open interest for one ticker. Select activity_type, call/put right, expiration, strike and observation-date filters; returns typed instrument fields, OHLC, volume or open interest with units and source support. Open interest is a position measure; trading volume is a flow. Use explicit date/instrument filters for large histories; source-file order is not a globally sorted latest option chain. Current requests recheck stale mirror metadata; historical/pinned reads remain fixed. Continue with the returned snapshot, cutoff, filters and cursor or next_offset; partial scans are not proof of no matches.
