## 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 kristo-intelligence-defi-arbitrage-opportunities-api-a4521cbf
```

Example prompt: Can you pull the latest DeFi arbitrage opportunities right now — I want to see what cross-protocol spreads are available I could act on?

## When to prefer this

Choose this endpoint when your AI agent needs real-time DeFi arbitrage opportunity data without managing API keys, and when you are operating in a crypto-native environment that supports x402 micropayment flows on Base. Ideal for autonomous trading agents, DeFi research pipelines, or any workflow where paying per-call in USDC is preferable to subscription billing. Prefer this over generic market data APIs when you specifically need cross-protocol arbitrage intelligence rather than simple price feeds.

## Known failure modes

- HTTP 402 returned when payment has not yet been submitted — this is the intended payment prompt, not an error; retry after paying
- Insufficient USDC balance on Base causes payment failure and no data returned
- Stale or empty opportunity list if markets are not currently showing arbitrage gaps
- Render.com cold-start latency if the service has been idle, causing slow first response
- Malformed or missing response if the underlying DeFi data feed is temporarily unavailable

## How this service works

DeFi market intelligence API for AI agents. No API keys — the HTTP 402 response IS the checkout. Paid per call, from $0.003/call (USDC on Base), retry, get data.

## Output

A list of current DeFi arbitrage opportunities, likely including protocol pairs, asset symbols, price discrepancies or spread percentages, estimated profit margins, and opportunity metadata — delivered as structured JSON after a micropayment of $0.005 USDC on Base is processed via the x402 protocol.
