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 stride20k-defi-tvl-lookup-c7e63e5a
```

Example prompt: What's the current total value locked in Aave? I want a live TVL number from DeFiLlama so I can check protocol health before making a yield decision.

## When to prefer this

Choose this endpoint when you need a single, normalized TVL figure for a named DeFi protocol without managing API keys or accounts. It is ideal for AI agents that need pay-per-call access to DeFi liquidity data sourced from DeFiLlama, especially in x402-enabled pipelines where USDC micropayments are already supported. Prefer this over direct DeFiLlama integration when you want schema-stable, normalized JSON with guaranteed response structure.

## Known failure modes

- Unknown or misspelled protocol slug returns a 404 or error response
- Upstream DeFiLlama outage may cause stale or failed data fetch
- Payment failure via x402 if USDC balance is insufficient
- Malformed protocol path parameter results in an error response
- Rate limiting if too many calls are made in rapid succession

## How this service works

Agent data gateway plus the live x402 market feed. Normalized, schema-stable JSON for crypto prices, DeFi TVL, on-chain DEX pools, gas, FX, US Treasury yields, US weather, WHOIS, DNS, email validation, web-page extraction, tech news, Wikipedia, npm/PyPI package health, ERC-20 token-risk scoring, and composed domain dossiers, plus x402 ecosystem analytics and metered LLM inference. Pay per call with USDC via the x402 protocol; no accounts, no API keys.

## Output

A JSON object containing the protocol's current TVL in USD (e.g. $13.25B), the canonical protocol slug, a boolean indicating whether the result was cached, the upstream data source (DeFiLlama), and the ISO 8601 timestamp of when the data was fetched.
