1inch API alternative for cross-chain buys
Stay with 1inch for Solana, two-way swaps and data APIs. For wallets whose users only buy a token on another network, a 1inch API alternative asks them to sign one stablecoin transfer, and the Unigox Trade API executes the purchase.
When to stay with the 1inch API
Your users start on Solana or sell as often as they buy
1inch cross-chain swaps run between EVM chains and Solana, in both directions. A Trade API purchase is paid in a stablecoin and only buys; selling the token later is a separate swap.
You want to start today, on your own
Sign-up at 1inch Business is self-serve and the Dev plan is free for 100,000 calls a month. API calls work once your organisation passes KYC or KYB, which can take up to two business days. Trade API access starts with a request and a review of the assets you want to offer.
One key also runs your balances, history and nodes
The same 1inch key covers the portfolio, balance, history, token, spot price and gas price APIs and managed RPC nodes. The Trade API does one thing: purchases on another network.
Where a 1inch cross-chain buy and a Trade API buy differ
Each row describes the same purchase: a user of your wallet holds a stablecoin on one network and buys a token, such as a tokenised stock, on another.
| Topic | 1inch API | Unigox |
|---|---|---|
| Who fills the purchase | Third-party resolvers compete in a Dutch auction. The winner deposits into escrows on both chains and pays the gas on each side. Once the token is approved, the user signs an order, not a transaction; from Solana, the user sends the escrow transaction on-chain. | Unigox delivers the stablecoin to the destination network and executes the purchase there. |
| What your app runs | Check the router allowance, generate secrets, place the signed order, then poll until both escrows exist and reveal each secret to finish. An order split between resolvers needs one secret per fill. | Your backend requests a quote, the user signs the stablecoin transfer, and your app reads the result. |
| If a purchase fails | After the timelock expires, a resolver or any participant cancels the swap and the assets go back to their original owners. The order then reads expired or refunded. | A stablecoin refund at the receiver's address on the destination network. Only gas used by a failed execution there comes off, never more than the gas charge in the quote. |
| Fees on the purchase | An infrastructure fee taken from the amount received: 10 bps on stablecoins and 30 bps on other tokens on the free Dev plan, falling to 2 and 5 bps on the Business plan. During the x402 launch, 1inch waives the swap infrastructure fee on calls paid by x402. | The quote states the delivered amount, the network execution fee and a deadline before the user signs. |
| Plans and your revenue | Free Dev plan; Startup at 149 or 199 USD a month by billing interval; custom plans per API; or pay per call in USDC on Base. Your own fee on each swap needs a paid plan and arrives on-chain in the swap token. | A share of trading revenue for you, agreed with Unigox together with access before you start. |
| Assets and direction | Swaps both ways between EVM chains and Solana, including tokenised stocks from issuers such as Ondo and xStocks where the issuer allows. xStocks orders under 20 USD are not filled. | Buying only, of assets such as tokenised stocks and meme coins. Unigox confirms each asset and network pair with you, and both networks must support the stablecoin your user pays with. |

List what your users buy
Request access on the Trade API page with the tokens and networks your users buy through 1inch cross-chain swaps today. Unigox reviews them and agrees terms with you, while your 1inch key keeps working.
Replace the order and secret loop
Drop the allowance check, secret generation and escrow polling for one quote request from your backend. Show the price, delivered amount and network fee, then ask the user to sign the stablecoin transfer.
Show the token or the refund
Read the result and show the token received, or the stablecoin refund and the network it landed on. Your app has to make that refund destination clear to the user.
Questions about a 1inch API alternative
What can replace the 1inch API for token purchases on another network?
For a wallet whose users only buy tokens on another network with a stablecoin, the Unigox Trade API: the user signs one transfer, Unigox executes the purchase, and a failed purchase is refunded in stablecoin on the destination network. For two-way swaps, Solana and on-chain data, 1inch covers more.
See the Trade APIHow is 1inch API pricing set, and how does the Trade API differ?
1inch sells access by plan: a free Dev plan, Startup at 149 or 199 USD a month depending on billing, custom plans per API, or pay per call in USDC on Base. Swaps add an infrastructure fee of 2 to 30 bps by plan and token. Trade API terms, including your share of trading revenue, are agreed before you start.
Who pays gas and fees on a 1inch cross-chain swap?
Resolvers pay the gas on both chains. The infrastructure fee is deducted from the amount the user receives, and the fee you set as integrator, on a paid plan, is paid on-chain in the swap token. On the Trade API, the quote states the network execution fee before the user signs.
Which 1inch competitors fill a purchase without a resolver auction?
The Unigox Trade API is one. Unigox delivers the stablecoin to the destination network and executes the purchase itself, so your app has no auction to wait on and no escrow secret to reveal. We also compare Unigox with deBridge, a cross-chain network filled by solvers.
