How this service works
Indicative Base mainnet swap pricing via the Coinbase CDP Trade API- expected output, min output after slippage, and fee estimates- WITHOUT reserving liquidity. Poll this to compare routes, then buy /v1/tx/swap for the executable quote. GET /v1/swap/price?fromToken=0x..&toToken=0x..&fromAmount=atomic&taker=0x..&slippageBps=100.
Output
Returns a JSON object with a quote containing toAmount (expected output in atomic units), minToAmount (minimum output after slippage), fee estimates, and the network identifier — without reserving or committing any liquidity.
Example use cases
Example prompt
“Before I execute anything, get me an indicative price quote for swapping 500 USDC (0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48) to WETH (0x4200000000000000000000000000000000000006) on Base mainnet for my wallet 0xAbCd...1234, using 100 bps slippage tolerance — just the price estimate, don't execute the trade.”
Technical details
Endpoint
GEThttps://ozmium.org/v1/swap/priceWhen to prefer
Use this endpoint when you want to compare swap routes or estimate output amounts before committing to a trade. It is the read-only price-check step in the Ozmium swap flow — call this first to evaluate pricing, then call /v1/tx/swap only when ready to execute. Prefer this over the executable swap endpoint whenever you need non-binding price discovery, route comparison, or slippage analysis without side effects.
Side effects
- Invalid or unsupported token addresses return an error or empty quote
- fromAmount of zero or non-numeric value causes a bad request
- Taker address missing or malformed may result in a 400 error
- Token pair with no liquidity route returns no quote or zero amounts
- Rate limit or upstream Coinbase CDP API error returns 5xx
- Missing required query parameters returns validation error
