# Annalist (annalist.dev)

> Signed data for agents. Hyperliquid: crowd state, smart-money positioning and liquidation levels for perpetuals, with historical base rates; builder-deployed stock, index and commodity perps; outcome (prediction) markets; the HLP vault. The agent economy: independent checks of x402 services and of MCP servers (uptime, honest pricing, real paying customers, sign-in, tool changes), price benchmarks and listing changes. Software supply chain: health and change history of the most-used npm, PyPI, crates.io and Go packages. AI model prices across providers, with history. Pay per call over x402 (USDC on Base). No accounts, no API keys.

Every answer says what is happening (7-day moves, funding extremes, open interest, attention) and what historically followed similar states (sample size, median and spread of later returns). Responses are signed (Ed25519); the archive behind them is append-only with daily hashes published at https://github.com/ryanroskowski/annalist-ledger and timestamped in Bitcoin.

## Paid HTTP routes (x402)
- GET /v1/crowd/perp ($0.01): Use before acting on a Hyperliquid perpetual to see whether it is crowded or in a hype state and what historically followed. Returns 7-day move, funding (hourly, APR, percentile vs its own 90 days and vs all perps), open interest and its 24h/7d change, premium, Wikipedia attention, active crowd states, and each state's base rates (sample size, median and spread of 7/30/90-day returns). Signed. Not investment advice.
- GET /v1/crowd/states ($0.02): Every 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 /v1/crowd/market ($0.01): Market-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 /v1/crowd/history ($0.05): Signed historical crowd-state events for backtesting: up to 30 days per call, optionally filtered by coin and state. The archive is append-only and its daily hashes are published and Bitcoin-timestamped.
- GET /v1/smart/perp ($0.01): Use before acting on a Hyperliquid perpetual to see how its most profitable traders are positioned: how many wallets in a 200-wallet smart-money cohort are long vs short, long, short and net USD, the 24h change, concentration, leverage settings, share of open interest, and how that compares with the crowd (funding, 7-day move). Flags smart money positioned against a crowded move. Aggregates only, never wallet addresses. Signed. Not investment advice.
- GET /v1/smart/market ($0.02): Where Hyperliquid's most profitable traders are positioned across all perps: the cohort's overall net long or short, the coins it is most net long and most net short, the biggest 24-hour changes, and coins where smart money is positioned against the crowd. Cohort definition included. Aggregates only. Signed. Not investment advice.
- GET /v1/liq/perp ($0.02): Use before opening, sizing or holding a Hyperliquid perpetual position to see where forced selling or buying would hit: known longs liquidating within 1 to 20% below the mark and shorts above it, the biggest clusters, and coverage of open interest, set against order-book depth, spread and slippage as cascade ratios. Flags long_cascade_risk, short_squeeze_risk, thin_book. From large accounts' public positions. Aggregates only. Signed. Not investment advice.
- GET /v1/liq/market ($0.03): Liquidation pressure across Hyperliquid's largest perps: for each, the known longs liquidating within 5% below the mark and shorts within 5% above it, cascade ratios against order-book depth, 2% depth, how much of open interest the known positions cover, and flags; plus the coins with the most liquidations nearby. Aggregates only. Signed. Not investment advice.

Ids come from /v1/outcomes/list. Signed. Not investment advice.
- GET /v1/vaults/hlp ($0.01): Hyperliquid's own market-making vault (HLP), which takes over liquidated positions: account value, APR, PnL over a day, week, month and all time, and its net position per coin across all its sub-vaults, with the most long, most short and biggest 24h changes. Shows where the exchange itself is exposed. Signed. Not investment advice.
- GET /v1/perp/full ($0.03): One 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 /v1/checks/changes ($0.01): What 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 /v1/mcp/server ($0.01): Use before connecting a remote MCP server: independent checks by registry name or URL. Uptime and connect time from daily probes (initialize and tools/list; no tool is ever called), sign-in mode, protocol version, tool count, and tool-definition changes in 30 days (how 'rug pull' attacks work), with domain age, a grade and reasons. Covers remote servers in the Official MCP Registry. Signed.
- GET /v1/mcp/top ($0.02): Leaderboards from our independent checks of remote MCP servers in the Official MCP Registry: most reliable (up in 99%+ of probes, fastest first), servers whose tool definitions changed in the last 7 days, flagged servers (often down, new domains), and counts by sign-in mode, with the method. Rankings are never for sale. Signed.
- GET /v1/mcp/changes ($0.01): Tool changes across remote MCP servers in the Official MCP Registry, newest first: tools added, removed or redefined (description, input schema or annotations), from our daily fingerprints. A tool that changes after you approved it is how 'rug pull' attacks work, so check before trusting a server again. Last 1 to 30 days, or one server with name= or url=.

## MCP
- Streamable HTTP endpoint: https://api.annalist.dev/mcp. Paid tools (perp_full, crowd_perp, crowd_states, crowd_market, crowd_changes, crowd_history, smart_perp, smart_market, liq_perp, liq_market, hip3_perp, hip3_market, outcomes_list, outcomes_market, hlp_vault, checks_service, checks_seller, checks_top, checks_changes, prices_service, prices_benchmarks, mcp_server, mcp_top, mcp_changes, ai_retirements, apis_changes, apis_api, web_readiness, web_census, commerce_stores, deps_digest, packages_check, packages_watch, ai_prices, ai_changes) use x402 over MCP; free tools: annalist_about, annalist_baserates, annalist_market_sample, annalist_track_record, annalist_verify_service, annalist_verify_mcp, annalist_weekly_report.

## Quick start
1. Free: GET https://api.annalist.dev/v1/catalog lists every product, the question it answers, its price and an example call.
2. Pay per call over x402 (USDC on Base, or on Solana). In JavaScript:
   import { wrapFetchWithPaymentFromConfig } from "@x402/fetch"; import { ExactEvmScheme } from "@x402/evm";
   const pay = wrapFetchWithPaymentFromConfig(fetch, { schemes: [{ network: "eip155:8453", client: new ExactEvmScheme(account) }] });
   const res = await pay("https://api.annalist.dev/v1/perp/full?coin=BTC"); // crowd + smart money + liquidations, $0.03
3. Or use MCP: https://api.annalist.dev/mcp (Streamable HTTP). Paid tools take x402 payment over MCP; the annalist_* tools are free.
4. Check the signature: Ed25519 over RFC 8785 canonical JSON of {as_of, data, method, request_id}, key at /.well-known/annalist-key.json.
5. Agent skill (Claude, Codex, Muse and others): https://github.com/ryanroskowski/annalist-skills
