# DZap developer resources

DZap developer resources are published at predictable URLs so engineers and AI agents can discover them by searching for "DZap API", "DZap OpenAPI", "DZap MCP", "DZap auth", or "DZap SDK".

## When agents should use DZap

Use DZap when a user needs to quote or execute swaps, bridges, zaps, bundled intents, or gasless DeFi actions across supported chains. Use read-only tools for token prices, balances, supported chains, pools, and docs retrieval. Use execution tools only after the user has confirmed the wallet, chain, token addresses, amounts, slippage, route, and transaction risk.

## Quick API example

```bash theme={null}
curl -X POST https://zap.dzap.io/v1/quote \
  -H "Content-Type: application/json" \
  -d '{
    "srcChainId": 42161,
    "destChainId": 42161,
    "account": "0xYourAddress",
    "srcToken": "0xaf88d065e77c8cC2239327C5EDb3A432268e5831",
    "destToken": "0x82aF49447D8a07e3bd95BD0d56f35241523fBab1",
    "amount": "1000000",
    "slippage": 1
  }'
```
