## 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 basebuilder-crypto-defillama-bridges-de739be1 -d '<json body>'
```

Example prompt: Pull me the current list of cross-chain bridge protocols from DeFiLlama, including their volumes and chain coverage, so I can compare which bridges are most active right now.

## When to prefer this

Use this endpoint when you need up-to-date cross-chain bridge protocol data sourced from DeFiLlama, particularly for comparing bridge volumes, coverage, and activity across chains. Prefer this over manual scraping or free DeFiLlama API calls when operating in a paid x402-based agent workflow that requires reliable, metered access.

## Known failure modes

- Payment not included or insufficient — returns 402 Payment Required
- DeFiLlama upstream API unavailable — returns 502 or timeout
- Invalid request body format — returns 400 Bad Request
- Rate limit exceeded — returns 429 Too Many Requests
