# DeFi Protocol TVL & Audit Data (DefiLlama)

> DeFi Protocol TVL & Audit Data (DefiLlama) is a paid API for AI agents from api.hyperd.ai, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-13).

Returns DeFi protocol TVL, audit records, and chain distribution sourced from DefiLlama — supports single-protocol detail via slug or a top-50 list view.

## 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 api-hyperd-ai-b6706235
```

Example prompt: What's the current TVL, audit history, and chain distribution for Aave? Pull the full protocol detail.

## When to prefer this

Use this endpoint when you need authoritative TVL data, audit history, or cross-chain distribution for a specific DeFi protocol, or when you need a ranked overview of the top 50 protocols. Prefer this over raw DefiLlama API calls when you want a pre-aggregated, pay-per-call interface without managing API keys.

## Known failure modes

- Unknown or misspelled slug returns empty result or 404
- Protocol not indexed by DefiLlama returns no data
- Missing both slug and list parameters may return default or error response
- Rate limiting or payment failure returns 402 error
- DefiLlama upstream outage causes stale or unavailable data

## How this service works

Protocol TVL, audits, chain distribution from DefiLlama. Pass ?slug=<protocol> for detail or ?list=true for top 50.

## Output

Returns TVL figures, audit records (auditors, dates, findings), and chain-level TVL distribution for the requested protocol; or a ranked list of the top 50 DeFi protocols by TVL when the list flag is set.
