## 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 peerlytics-liquidity-depth-history-october-2026-csv-d1902f07
```

Example prompt: Pull the Peerlytics USDC liquidity depth history for October 2026 as a CSV — I need the hourly observations showing listed depth, seller counts, best premium, and order book depth at the 0.5%, 1%, 2%, and 3% bands for Peer protocol.

## When to prefer this

Choose this endpoint when you need bulk, structured USDC liquidity depth data for the entire month of October 2026 from Peer (ZKP2P) on Base, especially for backtesting, research, or batch analysis workflows that benefit from CSV format. Prefer the JSON variant if you need programmatic row-by-row parsing without CSV parsing overhead. Use this over general DeFi analytics APIs when you specifically need Peer protocol's p2p liquidity microstructure data including seller depth bands and premiums.

## Known failure modes

- Payment not received or insufficient USDC (402 Payment Required)
- Month not yet fully elapsed — partial data for current month
- No observations recorded before the first crawl time (coverage gap at month start)
- Network or server timeout returning large CSV payload
- Invalid or missing x402 payment header causing authentication failure

## How this service works

Liquidity depth history, 2026-10, CSV. Hourly observations of public USDC liquidity per payment platform and currency: listed depth, sellers, best premium, largest order near mid-market and depth within 0.5%, 1%, 2% and 3% of mid-market. Past hours cannot be reconstructed, so coverage starts at the first observation.

## Output

A CSV file with one row per hourly observation for October 2026, covering each payment platform and currency pair supported by the Peer (ZKP2P) protocol. Columns include: listed depth, number of sellers, best premium available, largest order near mid-market, and liquidity depth at 0.5%, 1%, 2%, and 3% bands around mid-market price. Historical hours cannot be reconstructed, so data starts from the first recorded observation.
