# Layer 2 Scaling Solutions Overview

> Layer 2 Scaling Solutions Overview is a paid API for AI agents from api.web3identity.com, paid per call via x402, $0.010000/call, status unknown (last checked 2026-09-14).

Returns an overview of Layer 2 blockchain scaling solutions with metrics, statistics, and comparisons across multiple L2 networks

## Facts

- Endpoint: GET https://api.web3identity.com/api/l2/scaling
- Price: $0.010000/call
- Payment: x402

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 api-web3identity-com-aeda3794
```

Example prompt: Give me an overview of the current Layer 2 scaling solutions available for Ethereum, including their key metrics and how they compare to each other.

## When to prefer this

Use this endpoint when you need a broad, multi-network overview of Layer 2 scaling solutions in a single call. It is ideal for dashboards, research summaries, or when a user wants to understand the L2 landscape without specifying a particular network. For side-by-side detailed comparisons of specific L2 pairs, a dedicated comparison endpoint may be more appropriate.

## Known failure modes

- Payment required (402) if x402 payment of $0.01 USDC not provided
- Stale or unavailable data if upstream L2 metrics sources are down
- Empty or partial L2 list if some networks are temporarily unreachable
- Rate limiting if called too frequently without valid payment credentials

## How this service works

Layer 2 scaling solutions overview with metrics and comparisons

## Output

Returns a structured response containing an array of L2 solutions with their individual metrics and a summary object aggregating key statistics across all tracked Layer 2 networks, enabling comparison of throughput, cost, TVL, and other performance indicators.
