The free Basic plan works for moderate usage at around 333 calls per day. If your agent handles high traffic or needs historical OHLCV data, upgrade to the Hobbyist ($29/month) or Standard tier. Tars uses one API call per customer question that requires market data, so plan sizing depends on your daily conversation volume.

The agent calls CoinMarketCap's Cryptocurrency Quotes Latest endpoint using the coin's symbol, slug, or CoinMarketCap ID. It returns the current price, market cap, 24-hour volume, and percent change. The query runs in real time during the conversation, so data reflects the latest update cycle, typically within 60 seconds.

Yes. The Price Conversion endpoint supports conversion between any cryptocurrency and over 40 fiat currencies including USD, EUR, GBP, and JPY. You can also convert crypto-to-crypto, such as BTC to ETH. The agent handles the amount, source, and target parameters automatically based on what the user asks.

No. Every price query fetches live data from CoinMarketCap's API during the conversation. Tars does not maintain a local database of market data. Once the conversation ends, the retrieved data is not retained. This ensures users always receive the most current pricing available.

CoinMarketCap tracks over 10,000 cryptocurrencies. If a token is too new or delisted, the API returns an empty result. The agent communicates that the coin was not found and suggests the user verify the ticker symbol or check whether the project has been listed on CoinMarketCap yet.

Absolutely. The agent retrieves global metrics data and can contextualize it in plain language. For example, it might respond: 'Bitcoin dominance is currently 52%, meaning BTC accounts for just over half of the total crypto market capitalization of $2.1 trillion.' You can customize how technical or simplified these explanations are.

A widget displays static tables of data. The Tars AI Agent has a conversation. Users can ask follow-up questions like 'Now show me the 7-day trend' or 'Compare that to Solana.' The agent also works across WhatsApp and SMS where widgets are not an option, and it can combine CoinMarketCap data with your other business tools.

Yes. When configuring the tool in your Tars dashboard, you can instruct the agent to only fetch data for specific coins, restrict responses to certain fiat currencies, or avoid exposing exchange-level data. These guardrails help you tailor the experience to your platform's scope and compliance requirements.
