## 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 arbipulse-defi-yield-arbitrage-5a62781b
```

Example prompt: Show me the best borrow-deposit spread opportunities in DeFi right now — I want to see which protocols and chains have the biggest rate differentials I could exploit for a carry trade.

## When to prefer this

Use this endpoint when you specifically want to identify borrow-deposit spread opportunities across DeFi lending protocols (e.g. Aave, Compound, Morpho), as opposed to DEX price arbitrage, CEX spot arbitrage, or funding rate carry trades. Best for agents executing or evaluating interest-rate-based carry strategies in DeFi.

## Known failure modes

- Rate feed unavailable for a specific chain or protocol — partial results returned
- No profitable spreads found above a threshold — empty opportunity list
- Protocol RPC endpoint down — stale or missing data for affected chain
- Invalid or unsupported chain/asset filter — 400 error
- Payment not received or insufficient — 402 error blocking response

## How this service works

12 endpoints scanning arbitrage opportunities across DeFi yield spreads, DEX price differentials, perpetual funding rates, sports surebets, ETF/NAV gaps, and commodity regional pricing. Execution-tier calldata for AI agents. Payments via x402 protocol on Base mainnet (USDC $0.05–$0.20 per query). Part of PulseNetwork.

## Output

Returns a list of cross-protocol borrow/deposit spread opportunities, including the lending protocols involved, the asset, borrow and deposit rates on each side, the net APY spread, and the chain(s) involved, ranked by profitability.
