3Route Review 2026: Tezos DEX Aggregator and Agent Swap API

3Route is a DEX aggregator focused on Tezos. Its public description says it combines liquidity from several Tezos decentralised exchanges into a single swap interface. The project is built by Baking Bad, a Tezos tooling developer, and its site presents it as the leading DEX aggregator on Tezos, with more than 190 Tezos tokens and over 1,000 liquidity pools in its routing.

The product has two parts. The first is a web swap app where a Tezos user connects a wallet, picks a pair and signs one transaction. The second is an API for quotes and unsigned swaps, aimed at AI agents, bots, wallets and apps. The API is paid per call in USDC through x402 or MPP, and the site lists Ethereum, Monad, Robinhood Chain, Base and Etherlink as supported chains for that flow.

An independent listing on a public TVL tracker shows the product as a DEX aggregator with no token of its own and no recorded audits in that listing. The company's own site claims an audit by Inference. Separate third-party write-ups and public reporting describes the Tezos routing service and the agent API in similar terms.

The project does not publish its team names, a formal security policy, or a full fee schedule for partners. Those gaps matter more for a routing service than for a wallet, because the site handles the path of each trade.

A decentralised exchange, or DEX, is a smart contract that lets people swap one token for another against a pool of liquidity. Prices in each pool move with the size of the trade, so the same swap can give different outputs on different pools. An aggregator like 3Route reads several pools at once and finds the combination that returns the most tokens for the amount you put in.

On Tezos, 3Route says it processes each new block as it arrives, so quotes reflect the latest on-chain state rather than a cached price. When you request a swap, it returns a transaction that your wallet signs. The aggregator does not take custody of your tokens at any point in that flow.

For developers and AI agents, the same routing engine is exposed as an API. A quote call returns an expected input, output and gas estimate without building an executable transaction. A swap call returns an unsigned transaction that the caller compares with a fresh quote and then signs locally. Payments for those calls are made per request in USDC using the x402 or MPP standards, which are payment protocols for machine-to-machine requests.

The Tezos swap interface advertises a 0% service fee from 3Route itself. Users still pay Tezos network fees and any pool fees on the DEX routes the aggregator chooses, and the site does not publish a single consolidated fee table.

The agent API is priced per call. The site states a quote or swap call costs $0.001 with no subscription or API key, and that frequent users can use x402 batch settlement or MPP sessions. Partner API pricing is not published; the site says partners should contact the team.

3Route does not take custody of user tokens in the swap flow; each swap is a transaction the user signs in their own wallet. The main risks are smart-contract risk in the aggregator and in the DEX pools it routes through, plus market risk from price moves and low liquidity in thinly traded tokens.

The site states that its contracts were audited by Inference. The material available does not include the report, its date or its scope, and the public TVL listing shows no audits. Readers should check the audit themselves before relying on it.

For the agent API, the main risks are operational. An agent holding a signing key can move funds, so keys should be stored securely and transactions should be reviewed before signing. The project does not publish a regulatory status or a dispute process. Trading involves risk of loss. Check the rules that apply where you live before using any online financial service.

This product is for Tezos holders who swap tokens often and want a single transaction that searches several pools, and for developers and AI agent builders who need quote and unsigned swap calls without managing an API key.
