Overview

The Market API finds the best price across major DEXs and AMMs on 10+ EVM chains and returns it as ready-to-broadcast Augustus v6.2 calldata.

The Market API is Velora’s DEX aggregator, served as a REST API. One request prices your swap, a second turns the quote into calldata for the Augustus v6.2 router, and you sign and broadcast it yourself. All you need to start is a partner string to tag your app.

Want gasless, MEV-protected swaps instead of self-broadcast calldata? Call GET /v2/quote with mode=ALL and Velora returns a Delta intent or a Market route, whichever is better. See Trading modes.

Lifecycle

1. Price

   GET /prices — returns the optimal priceRoute (destAmount, gasCostUSD, bestRoute, and an hmac integrity tag).

2. Build

   POST /transactions/:chainId — turns the priceRoute into a broadcastable txParams envelope. Attach permit / permit2 here to skip the approve tx.

3. Approve

   ERC-20 approve(to, amount) against the Augustus v6.2 router (txParams.to). Native sources (ETH) skip this; the amount rides in txParams.value.

4. Send

   Estimate gas locally, sign txParams, and broadcast. Settlement is atomic: it reverts if the delivered amount falls below the slippage-adjusted minimum.

In a hurry? GET /swap fuses price + build into one call, at lower rate limits and without RFQ liquidity.

Endpoints

Method	Path	Purpose
GET	/v2/quote	Delta intent or Market route from one request (mode=DELTA, MARKET, or ALL)
GET	/prices	Best route for a token pair — inspect, display, or cache it
POST	/transactions/:chainId	Build ready-to-broadcast calldata from a priceRoute
GET	/swap	Route + ready-to-broadcast tx in a single call

SDK shortcut

Every endpoint is wrapped by sdk.swap.*. The SDK handles the price → build orchestration, allowance checks, and partner-fee defaults. For a 5-minute walkthrough see SDK → Market.
