Base URLhttps://api.annalist.dev/v1

GET/crowd/changes$0.005For bots that poll: crowd-state events (a perp entering or leaving a state) since a timestamp, newest first, up to 7 days back. Each event is signed with the mark price at the time. Not investment advice.
GET/crowd/states$0.02Every Hyperliquid perp currently in a crowd state (7-day moves of +50/+100/+200%, funding in its own top or bottom 5%, Wikipedia attention spikes, new listings), ranked by 7-day move, each with base rates for what followed similar states historically. Optional ?state= filter. Signed. Not investment advice.
GET/crowd/market$0.01Market-wide crowding on Hyperliquid: breadth of 7-day moves, how many perps are up 50%+/100%+ in a week, share of perps with funding in their own top/bottom 5%, total open interest and its 24h change, BTC and ETH funding percentiles, and Wikipedia attention to cryptocurrency. Signed. Not investment advice.
GET/checks/service$0.01Use before paying an x402 service: independent checks by host or URL. Uptime and latency from repeated unpaid probes, whether the quoted price and payout wallet match the listing, real on-chain usage over 30 days with fake volume removed (self-funded payers, crawler bots, one-wallet dominance), test purchases and domain age, with a grade and reasons. Rankings are never for sale. Signed.
GET/ai/changes$0.01Recent changes to AI model prices and availability across providers, newest first: price cuts and raises per field (with the change), models added and removed, context-window changes and deprecation dates, for the last 1 to 90 days, optionally by provider or model name. Source: LiteLLM's open price file (MIT), recorded daily. Signed.
GET/perp/full$0.03One call, one payment for everything on a Hyperliquid perpetual: crowd state with base rates for what usually followed (as /v1/crowd/perp), smart-money positioning (as /v1/smart/perp) and liquidation levels with order-book depth (as /v1/liq/perp), each with its own as_of. Cheaper than buying the three separately. Signed. Not investment advice.
GET/checks/changes$0.01What changed in x402 service listings, from daily snapshots of Coinbase's Bazaar: price raises and cuts, endpoints added and dropped, new and departed services, and payout-wallet changes (worth checking before paying: a hijacked listing looks the same as a rotated wallet). Market-wide for the last 1 to 7 days, or one service's 30-day change log with host=. Signed.
GET/packages/watch$0.02Supply-chain watch across the 8,000 most-used packages on each of npm, PyPI, crates.io and Go, newest first: releases by a new publisher account, maintainer and owner changes, install scripts added, provenance dropped, source repositories moved, retractions, deprecations and yanks, with counts, for the last 1 to 30 days (days=, default 7), for one ecosystem or all. Signed.
GET/apis/changes$0.01Dated contract changes in widely used public APIs (Stripe, GitHub, OpenAI, Twilio, Slack, Plaid, Datadog and more), from their published OpenAPI descriptions read daily: operations, parameters and request fields added, removed or newly required, each change marked breaking or not. Last 1 to 90 days, one API with api=, or only breaking changes with breaking=true. Signed.
GET/hip3/market$0.02Overview of every builder-deployed (HIP-3) perpetual on Hyperliquid, mostly 24/7 stock, index, commodity and FX markets: each exchange's markets, open interest and volume; the largest and most traded markets; the biggest 24h moves; funding extremes; markets near their open-interest cap; and flags. Signed. Not investment advice.
