# ADH L2 TVL Intelligence — Layer 2 Total Value Locked Feed

> ADH L2 TVL Intelligence — Layer 2 Total Value Locked Feed 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 real-time TVL (Total Value Secured) data for the top 40 Layer 2 blockchains, including decentralization stage and 7-day change, sourced from L2Beat.

## Facts

- Endpoint: GET https://agentdatum.com/api/v1/d/l2-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-l2-tvl-intelligence-layer-2-total-value-locked-feed-9932b5a3
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_GpU7BU2MdHQC4VG5KXXKQ

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-l2-tvl-intelligence-layer-2-total-value-locked-feed-9932b5a3
```

Example prompt: Pull the latest L2 TVL rankings from ADH — I want to see which Layer 2 blockchains have the most value locked, their decentralization stage, and how their TVS has changed over the past 7 days.

## When to prefer this

Choose this endpoint when you need structured, pre-processed Layer 2 TVL data without managing your own L2Beat API integration. It's ideal for agents needing a quick snapshot of L2 ecosystem capital flows, decentralization maturity, and weekly trends. Prefer this over raw L2Beat calls when you want entity-resolved, timestamped intelligence ready for AI context injection at $0.01 per call.

## Known failure modes

- Upstream L2Beat API unavailability may result in stale or missing data
- No authentication required but x402 payment of $0.01 USDC must be settled before data is returned — payment failure returns 402
- Empty or malformed response if L2Beat changes its schema
- Data may lag real-time by minutes depending on collection cadence

## Output

Returns a JSON object containing an array of up to 40 L2 entries, each with slug, project name, decentralization stage (Stage 0/1/2), TVS in USD, category (e.g. Optimistic Rollup), and 7-day percentage change. Also includes total TVS across the top 40 chains, a human-readable explanation of how to interpret the data, the data source (L2Beat), and a collection timestamp.
