# Scrapling x402 Data Store: Live DEX Volume by Protocol

> Scrapling x402 Data Store: Live DEX Volume by Protocol is a paid API for AI agents from scraplingdata.xyz, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-26).

Returns real-time 24h trading volume, LP fees, TVL, and pool stats for 1,200+ DEX pools across major protocols and 7 chains

## 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-data-store-live-dex-volume-by-protocol-5a55ecbe
```

Example prompt: Pull the latest 24h DEX volume breakdown by protocol — I want to see Uniswap, Curve, Balancer, PancakeSwap, Aerodrome and the rest ranked by volume with their TVL and LP fees, all computed on-chain.

## When to prefer this

Choose this endpoint when you need real-time, on-chain-computed DEX volume data covering 1,200+ pools across 7 major chains without relying on off-chain aggregators. It is ideal for DeFi analytics, protocol comparison, LP fee analysis, and market share tracking across Uniswap v2/v3/v4, Curve, Balancer, PancakeSwap, Aerodrome, Velodrome and more. Prefer it over CoinGecko or DeFiLlama API wrappers when you want verifiable on-chain sourcing and pay-per-call pricing with no subscription required.

## Known failure modes

- Payment not sent or insufficient USDC — 402 response requiring x402 payment
- Invalid query parameter type (e.g. non-integer limit) — 400 validation error
- Keyword filter matches no protocols — empty records array with total_rows 0
- offset beyond total rows — empty records array
- On-chain data refresh lag — updated_at timestamp may be minutes behind real-time
- Rate limiting if many requests submitted rapidly — potential 429 response

## How this service works

Live decentralized exchange volume per protocol: estimated 24h volume in USD, 24h LP fees, TVL, share of tracked 24h DEX volume, pools tracked and chains, plus a total row. Computed on-chain from pool fee accumulators (Uniswap v2/v3/v4, Curve, Balancer, PancakeSwap, Aerodrome, Velodrome and more; 1,200+ pools) on Ethereum, Base, Arbitrum, Optimism, Polygon, BNB Chain and Avalanche (7d/30d fields are null).

## Output

A JSON (or CSV) array of records, one per DEX protocol, each containing: rank, protocol name, category, chains active on, pools tracked, 24h volume in USD, 24h LP fees in USD, TVL in USD, share of tracked 24h DEX volume (%), and a data source label. Includes a total row, metadata fields (dataset name, title, updated_at timestamp, total_rows, returned_rows), and supports pagination via offset/next_offset. 7d and 30d volume fields are present but null.
