    description: The Velora Market API provides real-time optimal swap routing across 170+ DEXes on 12 EVM-compatible chains.

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.
