Introduction

ZERT is cross-chain swap infrastructure for wallets, exchanges, neobanks, and dApps. One integration gives your product access to 70+ chains, 900+ DEXs, and 6M+ liquidity pools through ZERT's routing and execution infrastructure.

ZERT scans live liquidity, ranks routes by real-world execution quality, stress-tests under simulated conditions, and executes privately — no MEV exposure, no front-running. Gas is covered by ZERT. Your users pay nothing extra.

ZERT is fully non-custodial. No KYC. No user accounts.

Base URL

https://api.gateway.zert.com/api/v1

All public endpoints live under /api/v1. Authentication uses Authorization: Bearer YOUR_API_KEY on every endpoint except GET /health.

Public Flow

The public swap flow is Quote -> Build -> Sign -> Submit:

1. POST /quote

2. POST /swap/build

3. GET /swap/{swapId}/signing until a signable payload is ready

4. Sign externally in the wallet or signer you control

5. POST /swap/{swapId}/signing with the signed artifact

Postman and GitBook help you inspect payloads and submit signed artifacts. They do not sign transactions.
