## 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 speraxos-lisdao-lisusd-repay-api-ead40948 -d '<json body>'
```

Example prompt: Repay 500 lisUSD on my lisDAO CDP that uses slisBNB as collateral from my wallet 0xABC123... — or use 'max' to repay the full amount outstanding.

## When to prefer this

Use this endpoint when an AI agent needs to programmatically repay lisUSD debt on a lisDAO CDP without managing API keys — ideal for automated DeFi portfolio management bots, health-factor protection agents, or wallet automation flows on BNB Chain that pay per-request via USDC on Base.

## Known failure modes

- Insufficient lisUSD balance in wallet to cover repayAmount
- Invalid or unsupported collateralToken (e.g. token not accepted by lisDAO)
- Wallet address malformed or not found on-chain
- CDP does not exist for the given wallet and collateral combination
- Payment via x402 fails due to insufficient USDC on Base for the $0.001 fee
- RPC or on-chain congestion causing transaction timeout

## How this service works

AI-powered DeFi intelligence APIs payable via the x402 HTTP payment protocol. No API key required — pay per request with USDC on Base. Identity-only (SIWX) endpoints are free for wallets with an agentcash identity.

## Output

Returns a transaction result or signed transaction payload confirming the lisUSD repayment against the specified CDP, including the amount repaid and updated debt position state on BNB Chain.
