Pre-trade risk verdict on a Base token, $0.02. Give a Base contract address and get: honeypot/transfer-simulation result, buy and sell tax, mint and owner privileges, verified-source status, blacklist and pausable flags, liquidity and holder concentration, scored 0-100 with the explicit red flags named. Aggregated live from honeypot.is, DexScreener, GoPlus and GeckoTerminal. Run it before buying, approving or LP-ing an unknown token.

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.

    "q": {

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.

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.

    "key": {
      "type": "string",

VAULT SEARCH: Search across ALL your stored memories by keyword. Finds matches in both memory keys and values. Returns up to 10 results. Unlike agent_memory where you need to know the exact key, this lets you discover what you've stored.

  "properties": {
