# GlianaAI Swap Build Tool

> GlianaAI Swap Build Tool is a paid API for AI agents from api.glianalabs.com, paid per call via x402, $0.005/call, status unknown (last checked 2026-10-27).

Builds a token swap transaction payload (quotes and structures a DEX swap) via GlianaAI's pay-per-call utility API

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability glianaai-swap-build-tool-15fa0b5b
```

Example prompt: Build me a swap transaction to trade 100 USDC for ETH on a DEX — I need the full transaction payload I can sign and submit on-chain.

## When to prefer this

Choose this endpoint when you need to programmatically build a DEX swap transaction payload without managing API keys or subscriptions — paying only $0.005 USDC per call via x402 on supported chains (Base, Solana, Algorand, BNB Chain, Tempo). Ideal for agents that need to construct swap calldata on-demand without a standing API contract.

## Known failure modes

- Insufficient liquidity for the requested token pair returns an error or empty route
- Unsupported token address returns a validation error
- Malformed input body or missing required fields returns a 400-level error
- Payment not received or insufficient USDC balance returns a 402 Payment Required
- Network congestion may cause stale quotes or timeouts
