How do I format the symbol ID to get specific exchange data?

CoinAPI uses a specific format: `EXCHANGE_TYPE_BASE_QUOTE`. For example, to get Bitcoin to USD on Bitstamp, use `BITSTAMP_SPOT_BTC_USD`. You can use the `list_symbols` tool to find exact identifiers.

Can I get the current price of Ethereum in Euros?

Yes! Use the `get_specific_rate` tool. Set `asset_id_base` to 'ETH' and `asset_id_quote` to 'EUR'. This will return the real-time average conversion rate.

What timeframes are available for OHLCV data?

The `get_ohlcv` tool supports various periods via the `period_id` parameter, such as `1MIN`, `1HRS`, `1DAY`, `1MTH`, etc. It defaults to `1DAY`.

About CoinAPI MCP Server

Equip your AI agent with institutional-grade cryptocurrency market intelligence via CoinAPI. This unified server provides your agent with instant access to real-time and historical pricing, volume, trades, and order book data across hundreds of crypto exchanges. Your agent can instantly fetch precise exchange rates, audit OHLCV (Open, High, Low, Close, Volume) data, and retrieve Level 2 order books without you ever manually checking an exchange. Whether you are tracking market momentum or building an automated trading strategy, your agent acts as a dedicated quantitative analyst through natural conversation.

Pydantic AI validates every CoinAPI tool response against typed schemas, catching data inconsistencies at build time. Connect 9 tools through Vinkius and switch between OpenAI, Anthropic, or Gemini without changing your integration code. full type safety, structured output guarantees, and dependency injection for testable agents.

What you can do

Market Rates — Retrieve current exchange rates between any cryptocurrency and fiat currency pair.
Timeseries Data — Fetch detailed OHLCV (Open, High, Low, Close, Volume) records to analyze price actions across various timeframes.
Trade Activity — Monitor the most recent executed trades on any specific exchange and symbol.
Order Book Depth — Access Level 2 order book data to analyze liquidity and bid/ask spreads.
Asset Intelligence — List all supported fiat and crypto assets, symbols, and integrated exchanges.

The CoinAPI MCP Server exposes 9 tools through the Vinkius. Connect it to Pydantic AI in under two minutes — no API keys to rotate, no infrastructure to provision, no vendor lock-in. Your configuration, your data, your control.

CoinAPI + Pydantic AI FAQ

Common questions about integrating CoinAPI MCP Server with Pydantic AI.

How does Pydantic AI discover MCP tools?

Create an MCPServerHTTP instance with the server URL. Pydantic AI connects, discovers all tools, and generates typed Python interfaces automatically.

Does Pydantic AI validate MCP tool responses?

Yes. When you define result types as Pydantic models, every tool response is validated against the schema. Invalid data raises a clear error instead of silently corrupting your pipeline.

Can I switch LLM providers without changing MCP code?

Absolutely. Pydantic AI abstracts the model layer. your CoinAPI MCP integration works identically with OpenAI, Anthropic, Google, or any supported provider.
