Signed data for agents: agentic-commerce census, dependency digest, x402/MCP checks, Hyperliquid
Annalist is a remote MCP server serving signed market, dependency, API and x402/MCP trust data to AI agents, with per-call USDC pricing on some tools.
Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.
Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.
Read https://sourceweft.com/mcp/io.github.ryanroskowski%2Fannalist/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.Add this to your client's mcpServers config.

}Annalist (annalist.dev) keeps an append-only archive of crowd-state data for AI agents. This public repository is its ledger: once a day it records a fingerprint of everything the archive wrote the day before, signed and timestamped in Bitcoin. It lets anyone check that a record existed on a given date, so the history cannot have been backfilled or quietly edited later.
ledger/YYYY/MM/YYYY-MM-DD.json: one entry per UTC day.
entry.manifests: every run manifest written that day, each with the sha256 of the manifest file.entry.root: sha256 of the manifest hashes joined by newlines, in the listed order.signature: Ed25519 over the canonical JSON of entry (keys sorted, no spaces, UTF-8).ledger/YYYY/MM/YYYY-MM-DD.json.ots: an OpenTimestamps proof that the entry file
existed at that time. Proofs start as pending and are upgraded to full Bitcoin attestations within a day or two.keys/<key_id>.json: public signing keys. The current key is 187e49f200625a2f.Each run manifest in turn lists every archive file written by that run with its sha256 and size, and is signed with the same key. Data responses served by the Annalist API carry the same kind of signature.

Everything on one Hyperliquid perp
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. Price: $0.03 USDC per call via x402 (Base or Solana).
coinrequiredCrowd state for one Hyperliquid perp
Use before acting on a Hyperliquid perpetual to see whether it is crowded or in a hype state and what historically followed.

Optional ?state= filter. Signed. Not investment advice. Price: $0.02 USDC per call via x402 (Base or Solana).

Crowd-state events since a time
For 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. Price: $0.005 USDC per call via x402 (Base or Solana).
sincerequiredHistorical crowd-state events
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. Price: $0.05 USDC per call via x402 (Base or Solana).
torequiredcoinfromrequiredstateSmart-money positioning for one perp
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. Price: $0.01 USDC per call via x402 (Base or Solana).
coinrequiredSmart-money positioning across all perps
