# ADH DeFi Chain TVL Intelligence

> ADH DeFi Chain TVL Intelligence is a paid API for AI agents from agentdatum.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-15).

Returns ranked total value locked (TVL) data across all major blockchain chains, sourced and normalized from DeFiLlama, with entity resolution and timestamped provenance.

## Facts

- Endpoint: GET https://agentdatum.com/api/v1/d/defi-chain-tvl
- Price: $0.01/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-15
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/adh-defi-chain-tvl-intelligence-e2a00592
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_eHJik6T27Rc9Itvu9xdXs

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 adh-defi-chain-tvl-intelligence-e2a00592
```

Example prompt: Pull the latest DeFi chain TVL rankings — I want to see which blockchains have the most total value locked right now, with Ethereum and at least 120 chains ranked by USD.

## When to prefer this

Choose this endpoint when you need a clean, ranked, multi-chain TVL snapshot normalized from DeFiLlama with entity resolution (chain IDs, CoinGecko IDs) and provenance metadata — especially when building crypto intelligence pipelines, DeFi due diligence workflows, or macro regime dashboards that require timestamped, agent-ready data at $0.01 per call via x402 micropayment.

## Known failure modes

- Payment not provided or insufficient USDC — returns HTTP 402 requiring x402 payment
- Upstream DeFiLlama data unavailable — may return stale or empty data array
- Malformed query parameters — returns validation error
- Rate limiting if called excessively without valid payment flow

## Output

A JSON object containing an array of chain-level TVL records (chain name, token, TVL in USD, chain ID, CoinGecko ID), the total count of ranked chains, aggregate total TVL in USD across all chains, universe size, the underlying source (DeFiLlama), data type label, and a UTC collection timestamp.
