## 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-json-d8bf14f9
```

Example prompt: Pull me the full October 2026 hourly USDC liquidity depth dataset from Peerlytics — I want to see listed depth, seller counts, best premiums, and the order book depth within 0.5%, 1%, 2%, and 3% of mid-market across all payment platforms.

## When to prefer this

Use this endpoint when you need structured, machine-readable (JSON) historical USDC liquidity data for October 2026 specifically, with granular hourly resolution across multiple price bands and payment platforms. Prefer this over the CSV variant when downstream processing favors JSON. Prefer the 'all published rows' endpoint if you need data spanning multiple months. Prefer this over generic DeFi APIs when you specifically need peer-to-peer (ZKP2P/Peer protocol on Base) order book depth metrics rather than DEX or CEX liquidity.

## Known failure modes

- No data yet if the observation period hasn't started (coverage begins at first recorded snapshot)
- Sparse rows early in the month if monitoring started mid-October
- Missing values (null) for platforms or currencies with no active orders at a given hour
- Network or payment failure if the x402 USDC micropayment of $0.25 is not processed correctly
- Large response payload if the full month contains many hourly rows across multiple platforms

## How this service works

Liquidity depth history, 2026-10, JSON. 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 JSON file containing all hourly observations recorded during October 2026, with columns: platform_id, currency, observed_at, listed_usdc, sellers, deposits, best_premium_pct, largest_order_within_2pct_usdc, usdc_within_0_5pct, usdc_within_1pct, usdc_within_2pct, usdc_within_3pct, sellers_within_0_5pct, sellers_within_1pct, sellers_within_2pct, sellers_within_3pct. Coverage begins at the first observation captured; past hours cannot be reconstructed.
