query-token-info

Call the token search endpoint with the contract address as the keyword parameter, optionally filtering by chainIds such as 56 for BSC or 8453 for Base. The response returns matching tokens with price, volume, market cap, and social links.

Use the token dynamic data endpoint with the chainId and contractAddress parameters. It returns current price, percent changes across 5m to 24h, volume, liquidity, market cap, holder count, and top-10 holder percentage.

Token search, metadata, and dynamic data support BSC (chainId 56), Base (chainId 8453), and Solana (chainId CT_501). The K-Line endpoint additionally supports Ethereum via the platform parameter value eth.

Call the K-Line endpoint with the token address, platform (eth, bsc, solana, or base), and an interval such as 1min, 1h, or 1d. Each candle is returned as an array of open, high, low, close, volume, timestamp, and transaction count.

All numeric fields like price, volume, and market cap are string-encoded to preserve precision for large decimal values. Convert them to numbers in your code before performing calculations or comparisons.

The search, metadata, and dynamic data endpoints use numeric chainId values like 56 or CT_501, while the K-Line endpoint uses string platform values like bsc or solana. Check the mapping table before constructing K-Line requests.
