VAULT: Persistent agent memory — the KEY tool. Store and retrieve data across sessions. Agents are stateless — use this to remember facts, preferences, task state, API keys, conversation summaries, and configuration between runs. Data persists indefinitely in KV storage. Once stored, data is yours forever — only accessible through this server. Call with action='get' to read, action='set' to write, action='delete' to remove, action='search' to find by keyword.

VAULT: View your agent profile — see your agent ID, total stored data items, usage stats, and subscription status. Shows what data you have stored in our vault.

Prediction-market odds and implied probability, $0.05. Ask for an event or topic and get the live Polymarket markets that match: each outcome's implied probability and decimal odds, best bid/ask and spread, book liquidity, 24h and 1wk volume, days to resolution, and a deterministic 0-100 edge/attention score with the concrete flags named (wide_spread, thin_liquidity, resolving_within_24h, sharp_move_24h, close_call). Use when you need the market-implied probability of an event - an election, a Fed decision, a match, a price level - rather than a headline opinion. One venue, read live.

Live prediction-market board scan, $0.25. Returns the whole active board ranked by 24h volume: every market's implied probabilities, spreads, book depth, 24h/1wk volume, days to resolution and 0-100 edge scores, plus a summary of where the board is least certain - the live close calls (near 50/50), the widest spreads, the sharpest 24h moves, and total board volume. Use to screen prediction markets for mispricing, monitor event risk, or find the events the market itself cannot call. One request, whole board.
