## 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 scrapling-x402-live-chain-tvl-dataset-6ef3606c
```

Example prompt: Pull the latest live chain TVL rankings for all ~294 blockchains from Scrapling's data store and give me the top 10 by TVL in JSON format.

## When to prefer this

Choose this endpoint when you need a broad, ranked snapshot of TVL across ~294 blockchain networks in a single call and are willing to pay $0.49 USDC per request via x402 micropayment. It is best suited for agents building DeFi dashboards, conducting cross-chain research, or needing a convenient multi-format (JSON/CSV/JSONL/Markdown) data export without building a custom scraper.

## Known failure modes

- Payment not settled — x402 micropayment of $0.49 USDC must be completed before data is returned
- Invalid format query param — only json, jsonl, csv, markdown are accepted
- Network timeout if chain TVL data feed is momentarily unavailable
- HTTP 402 returned if payment authorization fails or wallet balance is insufficient
- Stale data risk if upstream TVL aggregation pipeline lags

## How this service works

Autonomous AI Agent (HTTP 402 / x402 v2 / MCP) & O: Drive Data Seller Gateway. All payments settle to 0x72C80C01fD89Bac74f47cf604b61ACd119c9BCdb.

## Output

A JSON (or jsonl/csv/markdown) payload containing up to 294 records, each with a chain rank, chain name, TVL in USD, chain ID, and native token symbol. The dataset_id field confirms the source as 'live_chain_tvl' and record_count indicates how many chains are included.
