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 quietsignal-l2beat-snapshot-4d870fef
```

Example prompt: Pull the latest L2BEAT snapshot showing the top 10 rollups ranked by TVL so I can compare Ethereum Layer 2 projects.

## When to prefer this

Choose this endpoint when an AI agent needs structured, machine-readable L2 project rankings and TVL data sourced from L2BEAT without scraping the L2BEAT website directly. It is ideal for agents that need per-request, pay-as-you-go access (via x402/USDC) without API key registration. Prefer it when you need category-filtered rollup data (rollups, validiums, others) in a normalized JSON schema ready for downstream analysis.

## Known failure modes

- Payment required (HTTP 402) if USDC payment header is missing or insufficient
- Invalid tab enum value returns a validation error
- Limit outside 1–100 range is rejected
- Upstream L2BEAT data unavailable causes stale or empty project list
- Raw IP/sslip.io hostname may trigger TLS warnings in some clients

## How this service works

QuietSignal Public Data: independent, read-only rollup, wallet, opportunity, and developer-data facts for agents, paid per request with USDC over HTTP 402 on Base.

## Output

A JSON object containing a versioned L2BEAT snapshot with a list of ranked Layer 2 projects, a project count, the source URL, schema version identifier, and a disclaimer about third-party data and commercial rights. Optionally scoped to a specific L2BEAT category tab and limited by count.
