How this service works
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.
Output
A change-only packet per tracked asset containing: funding sign or band, funding trend, open-interest regime, active alert set, and data-source staleness/recovery status — plus per-asset freshness timestamps, a next-poll datetime derived from the 5-minute collection cadence, and a next_cursor for the subsequent call. Returns an explicit no-change packet when nothing has moved.
Example use cases
Funding rate reversal alert bot
“Poll Kronos Market Pulse for BTC and ETH and tell me if the funding sign flipped or the funding trend changed since my last cursor — I only care about what actually changed, skip no-change packets.”
Multi-asset derivatives watchlist
“Check Kronos Market Pulse for BTC, ETH, SOL, BNB, and AVAX and give me their current open-interest regimes and alert sets — use my saved cursor from the last call so we don't repeat data.”
Automated agent polling cadence
“After fetching the Kronos Market Pulse for BTC, tell me what the next recommended poll time is so my agent knows exactly when to check again without hammering the API.”
Technical details
Endpoint
GEThttps://kronossignals.com/api/v1/market-pulse?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need efficient, incremental polling for crypto market microstructure signals — specifically funding rates, open-interest regimes, and alert sets — without re-fetching unchanged data. Ideal for autonomous agents that run on a tight polling loop and need explicit no-change semantics plus a server-derived next-poll time. Prefer it over full-snapshot endpoints when bandwidth efficiency and change-detection latency matter, or when you need to track up to 5 assets simultaneously in one call.
Side effects
- Invalid or expired cursor returns an error or falls back to a full snapshot
- More than 5 assets in the comma-separated list causes a validation error
- Unknown asset slug returns an error or is silently dropped
- Upstream data source stale flag triggers a recovered/stale status rather than fresh data
- Payment not settled via x402 returns a 402 Payment Required response
