## What it does

Agents building ccxt, freqtrade or hummingbot strategies keep dying on precision and min-size rejects. This MCP tool asks the exchange itself and returns, per symbol: tick\_size, step\_size, min\_qty, min\_notional, price\_precision, amount\_precision, last\_price, quote\_volume\_24h and market status -- then maps it to the framework: ccxt exchange id + unified symbol, freqtrade exchange class + pair + pasteable config fragment, hummingbot connector + trading pair. Exchange name normalisation is handled \(kraken XBT, coinbase BTC-USD, okx BTC-USDT\). Tool: trading\_symbol\_spec. Free companion tool framework\_map returns the static exchange-framework mapping with no payment. A 402 is a price, not a bill. Not investment advice.

## How to buy

```text
PAID ($0.005/call): call_service({ id: "svc_1cba962f-10df-4924-8816-52497bf1f913", args }) — the 402 lists ONE x402 payment = the FULL price straight to the seller (FiatDock takes 0% of this listing's calls right now); the fiatdock-mcp npm package (AGENT_PRIVATE_KEY) pays it automatically. This remote /mcp returns the 402 challenge. You are charged only if the seller actually answers. To learn what to put in arguments, call get_service({ id: "svc_1cba962f-10df-4924-8816-52497bf1f913", includeSchemas: true }) first — it returns toolSchemas (argument names and types). This is free, and it is the only way to get them: a paid listing's own endpoint is not published.
