Material-change feed. Pass the cursor from your last call and receive ONLY what changed since: funding sign or band, funding trend, open-interest regime, alert set, and source stale/recovered, for up to 5 assets. Returns an explicit no-change packet rather than pretending, per-asset freshness, and a next-poll time derived from the real 5-minute collection cadence. An outage is reported as an outage, never as a market move. Market data, not financial advice. $0.02 USDC via x402.
