## 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 onesource-deepstate-market-cost-to-quote-analytics-0c555191
```

Example prompt: Can you pull the gas cost analytics for Deepstate order book 'ETH-USDC' from January 1 to January 31, broken down by 1-hour buckets, so I can see how much was spent on rests and cancels?

## When to prefer this

Use this endpoint when you need gas cost analytics specifically for a Deepstate order book market — it provides granular fee breakdowns (L1 vs total, rests vs cancels) with time-bucketed aggregations that generic EVM RPC endpoints cannot supply. Prefer this over raw RPC calls when you need pre-aggregated cost-to-quote metrics rather than raw transaction data.

## Known failure modes

- Missing required 'book' query parameter returns a 400 error
- Invalid 'res' enum value (not '1h' or '1d') returns a validation error
- Invalid or non-existent book ID returns empty or error response
- Date range with no data returns empty buckets or zero totals
- Payment failure or missing x402 payment header returns 402 Payment Required

## How this service works

Deepstate, the on-chain order-book exchange on Robinhood Chain. Gas spent resting and cancelling orders for a market.

## Output

Returns aggregated gas cost metrics for the specified order book and time range, including: total fee, median fee, L1 fee, L1 share percentage, rest count, cancel count, and transaction count — both as overall totals and broken down into time buckets (1h or 1d) with market session labels.
