# x402.ottoai.services DeFi Protocol Analytics

> x402.ottoai.services DeFi Protocol Analytics is a paid API for AI agents from x402.ottoai.services, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-15).

Returns DeFi protocol analytics including TVL rankings, chain breakdowns, gainers/losers, and per-protocol deep dives.

## Facts

- Endpoint: GET https://x402.ottoai.services/defi-analytics
- Price: $0.001/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-15

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 x402-ottoai-services-7151a6b6
```

Example prompt: Give me a DeFi market overview — show the top protocols by TVL, which ones are gaining or losing, and break it down by chain. Then do a deep dive on Aave specifically.

## When to prefer this

Use this endpoint when you need a broad DeFi market overview (TVL rankings, gainers/losers, chain breakdowns) or a focused deep dive on a specific protocol. Prefer this over general crypto price endpoints when the user cares specifically about DeFi protocol metrics and TVL rather than token prices or yield rates.

## Known failure modes

- Invalid or unrecognized protocol slug returns an error or empty result
- Network or upstream data provider outage returns a failed status
- Missing required input wrapper causes schema validation error
- Rate limiting or payment failure results in 402 payment required

## How this service works

Where DeFi capital is flowing — TVL rankings, fastest-growing vs bleeding protocols, chain-by-chain breakdown, and per-protocol deep dives. Track capital rotation and protocol health. Powered by DefiLlama.

## Output

A text report (string) with DeFi protocol analytics: TVL rankings across protocols, chain-level breakdown, top gainers and losers, and optionally a detailed view for a specific protocol if a slug is provided.
