description: ParaSwap (now Velora) is a DEX aggregator that enables dApps and traders to get the best swap rates by aggregating
  liquidity across 170+ DEXes and liquidity pools on 12 EVM-compatible chains. The platform offers two core APIs — the Market
  API for optimal route discovery and transaction building, and the Delta API for intent-based, gas-less swaps with MEV protection
  — plus an AugustusRFQ API for market makers to provide on-chain limit orders and peer-to-peer trading.

  description: The Velora Market API provides real-time optimal swap routing across 170+ DEXes on 12 EVM-compatible chains.
    Developers can retrieve price quotes with optimal routes (GET /prices), build transaction call data (POST /transactions),
    or combine both in a single call (GET /swap). Supports v5 and v6.2 of the Augustus smart contract.

- name: ParaSwap Delta API
  description: The Velora Delta API is an intent-based protocol that enables gas-less token swaps where multiple agents compete
    to execute trades on behalf of users. Users sign a Delta Order (EIP-712 off-chain signature) rather than making transactions
    themselves, which provides MEV protection through the Portikus Intents network. Currently supports Ethereum and Base networks.

- name: ParaSwap AugustusRFQ API
  description: The AugustusRFQ API enables market makers to integrate with ParaSwap's on-chain limit order and Request-for-Quote
    system, supporting fungible token (ERC-20) and NFT trading. Market makers implement a standardized HTTP specification
    for providing token listings, pair data, price curves, and signed firm orders. Supports optional HMAC-SHA256 authentication
    and optional WebSocket streaming for real-time price updates.
