Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 joe-market-data-defi-analytics-8cc33af6
```

Example prompt: Pull the latest DeFi analytics from DefiLlama — I want to see which chains and protocols have the highest TVL right now, and optionally filter by the Lido protocol.

## When to prefer this

Choose this endpoint when you need aggregated DeFi TVL data across chains and protocols from DefiLlama, especially within an Otto-compatible or x402-payment agent pipeline. Prefer this over direct DefiLlama API calls when you need a pay-per-call micropayment model on Base with no API key management.

## Known failure modes

- Invalid or unrecognized protocol slug returns no data or an empty result set
- DefiLlama upstream unavailability may cause delayed or failed responses
- Missing required 'input' object in the request body returns a validation error
- Rate limiting or payment failure may result in 402 responses

## How this service works

Public-data market intel for AI agents: token prices (CoinGecko), DefiLlama TVL/fees/stables, Polymarket odds. Otto-compatible path names. $0.001 USDC per call on Base. No LLM/TTS/image.

## Output

Returns a JSON object with a 'data' field containing an array of chains with their TVL values, a list of top protocols with their TVL, and a 'meta' field confirming the source (DefiLlama), endpoint path, and cost (0.001 USDC).
