How this service works
Interpreted wallet data for more than 40 chains and Solana: portfolios, DeFi positions, PnL, transactions and NFTs. REST for apps, x402 pay-per-call for agents.
Output
Returns an array of JSON:API resource objects, each representing a swap quote with attributes such as output token amount, price, route details, and related metadata, plus pagination/self links.
Example use cases
Cross-chain swap price check
“What's the best quote to swap 500 USDC on Arbitrum for ETH on Ethereum mainnet? My wallet address is 0xAbc...123 for both sending and receiving, with 1% max slippage.”
Same-chain DeFi trade planning
“Before I execute anything, can you get me a Zerion swap quote for trading 2 WBTC for USDC on Polygon? Use my address 0xDef...456 as sender and recipient, allow 0.5% slippage.”
Agent portfolio rebalancing quote
“I want to rebalance — can you pull a swap quote from Zerion to convert 1000 USDC to DAI on Base, from wallet 0x111...222 to the same wallet, with 0.3% slippage tolerance?”
Technical details
Endpoint
GEThttps://api.zerion.io/v1/swap/quotes?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need on-demand, real-time swap quotes across 40+ EVM chains and Solana via a single API, especially in agent workflows where pay-per-call (x402) billing is preferred over subscription keys. Ideal for pre-trade analysis, portfolio rebalancing agents, or price comparison before executing a swap.
Side effects
- Missing required query parameters (input chain_id, fungible_id, amount, output fungible_id, from, to) returns a 400 error
- Invalid or unsupported chain/token IDs return no quotes or an error
- Insufficient liquidity for the requested swap pair may return an empty data array
- Payment failure (x402) if USDC balance is insufficient for the $0.01 per-call fee
- Network or provider latency causing timeout on quote aggregation
