## 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 blockrun-defillama-protocol-lookup-7f8b95cf
```

Example prompt: Pull the DeFiLlama protocol data for 'uniswap' — I want to see its TVL and other metrics.

## When to prefer this

Use this endpoint when you need DeFiLlama protocol data without setting up a DeFiLlama API key, want pay-per-call micropayment billing in USDC on Base or Solana, or are operating in an agent environment (OpenClaw, Claude Code, Franklin Agent) where per-call crypto settlement is preferable to subscription API keys.

## Known failure modes

- Invalid or unknown protocol slug returns empty or error response
- Payment failure in USDC settlement prevents call from completing
- DeFiLlama upstream unavailability causes timeout or 503
- Malformed slug (e.g. spaces, wrong casing) may return no data
- Rate limiting or insufficient USDC balance blocks request

## How this service works

14M+ on-chain transactions. The routing & payment layer for AI. One endpoint routes to every frontier model — payment built in, settled in USDC on Base & Solana. One install for OpenClaw, Claude Code, or Franklin Agent.

## Output

Returns a JSON object containing DeFiLlama protocol data for the specified slug, including metrics such as TVL, protocol details, chain breakdown, and historical data as provided by DeFiLlama's API.
