Material-change feed for up to 5 crypto assets
Material-change feed for up to 5 crypto assets. 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. Returns an explicit no-change packet rather than pretending, plus per-asset freshness and a next-poll time derived from the real 5-minute collection cadence. Market data, not advice. $0.02 USDC via x402.
