## 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 claw402-polygon-grouped-daily-aggregates-e18cb87c
```

Example prompt: Can you pull the grouped daily bar data for all tickers from Polygon for 2024-01-15, with adjusted prices and OTC included, and pay for it with my USDC wallet?

## When to prefer this

Use this endpoint when you need market-wide daily OHLCV bar data for all tickers on a specific date and want to avoid API key registration by paying per-call with USDC. Prefer this over direct Polygon.io access when operating in a wallet-native, keyless agent environment.

## Known failure modes

- Payment not received or insufficient USDC — HTTP 402 returned, no data
- Invalid or missing date parameter — empty data array or error code returned
- Date falls on a non-trading day (weekend/holiday) — empty data array returned
- Malformed query parameters — API returns error response
- Network timeout or upstream Polygon.io outage — service unavailable

## How this service works

Backed by vergex.trade. Pay for any API with USDC. No API keys. No registration. Just a wallet.

## Output

A JSON object with a status code and an array of daily OHLCV aggregate bars for all tickers on the requested date, including open, high, low, close, volume, and related fields as returned by Polygon.io's grouped daily endpoint.
