An intent, a sell token, a buy token. The Ophis API does the rest — quote, route, MEV protection, settlement. Hit it from JavaScript, Rust, or just curl.

# Get a quote for 100 USDC -> WETH on Optimism
curl -X POST https://ophis.fi/api/intent \
  -H "Content-Type: application/json" \
  -d '{
    "intent": "swap 100 USDC for WETH on Optimism",
    "from": "0x..."
  }'

# Returns a signed order ready to relay to the Ophis settlement stack.

Built for real flow.

MEV protection

Batch auctions, off-chain solver competition. Users never lose surplus to frontrunners.

Volume-tier rebates

High-volume agents and DAOs earn fee rebates automatically via the rebate-indexer.

Agent-safety SDK

Receiver-pin checks, chain-id validation, partner-fee config — guardrails out of the box.

@ophis/sdk

Ship integrations in an afternoon.

Receiver-pin checks, chain-id validation, partner-fee config — everything an agent needs to swap without footguns.

npm i @ophis/sdk View on GitHub

JavaScript

import { configurePartnerFee } from '@ophis/sdk'

const order = configurePartnerFee({
  chainId: 10,
  receiver: '0xYourSafe...',
  bps: 25, // 0.25% of surplus
})

// receiver-pin + chain-id checks happen automatically

Built on the rails DeFi already trusts.

Forked from CoW Protocol's settlement stack. Same MEV-protection guarantees, Ophis-controlled allowlist, in-house solver competition.
