WHAT IT DOES

What get_dex_price_candles does on Tanod

AI agents call get_dex_price_candles to retrieve information from Tanod without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

Parameter	Type	Required	Description
`pair`	string	Yes	WETH/USDC (ETH in USDC, Uniswap v3 0.3% pool on Base) or cbBTC/USDC (BTC in USDC, Uniswap v3 0.05% pool on Base).
`limit`	object	—	Number of candles, newest last. Default 48 (1d: 30). Lookback caps: 5m and 15m 200, 1h 168, 4h 42, 1d 30.
`interval`	string	—	Candle length, UTC-aligned.

Parameters from the server's own tool schema.

RISK

Why get_dex_price_candles is rated Low

Even though get_dex_price_candles only reads data, uncontrolled read access leaks sensitive information and racks up API costs: an agent caught in a retry loop can make thousands of calls a minute without anyone noticing.

FAQ

Questions about get_dex_price_candles

What does the get_dex_price_candles tool do? +

chainpeek: Get ETH or BTC OHLCV price candles from on-chain DEX swaps. For the oracle price now use get_token_price. Returns OHLCV candles for ETH (WETH/USDC) or BTC (cbBTC/USDC) in USDC from public Uniswap v3 swaps on Base, at 5m, 15m, 1h, 4h or 1d, with the pool, fee tier and the block the data is current to (about a minute behind). Computed by Tanod from one allow-listed pool per pair, not an exchange feed: DEX prices can differ from centralized exchanges; a candle without swaps repeats the previous close; the last candle is still forming. Informational only, not investment advice. A bad pair, interval or limit is a 422 before any payment; a 503 warming_up (index still loading) or rpc_unavailable is not charged. Typically under 0.1 s (served from an index kept current in the background). Price: USD 0.003. Free: 10 chain reads per IP per UTC day. Docs: https://tanod.dev/learn/crypto-ohlcv-candles-api.html. It is categorised as a Read tool in the Tanod MCP Server, which means it retrieves data without modifying state.
