## How to call it through Zero

```sh
zero fetch --capability agentservices-defi-tvl-lookup-deb0a577
```

Example prompt: Pull the top 10 DeFi protocols by total value locked on Ethereum right now so I can see where liquidity is concentrated.

## When to prefer this

Use this endpoint when an AI agent needs real-time or near-real-time DeFi TVL rankings, especially when filtering by a specific blockchain. Prefer this over general web search when structured, machine-readable TVL data is needed for analysis, dashboarding, or yield strategy decisions. The $0.02 per-call x402 micropayment model makes it suitable for on-demand agent queries without subscription overhead.

## Known failure modes

- Invalid chain name returns empty results or an error
- Limit exceeding available data silently returns fewer results
- Stale data if upstream TVL source has not refreshed recently
- Payment failure via x402 micropayment if wallet balance is insufficient
- Rate limits or access errors if the x402 payment is not properly handled

## How this service works

Paid data APIs for AI agents. Crypto market data, DeFi yields, IP geolocation, dispute resolution, marketing intelligence. Powered by x402 micropayments on Base.

## Output

Returns a list of DeFi protocols with their Total Value Locked (TVL) figures, optionally scoped to a specific blockchain. Each record likely includes protocol name, chain, and USD TVL amount. Results are limited to the requested count.
