## 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 blockrun-polymarket-candlesticks-e2fffea0
```

Example prompt: Pull the candlestick price history for Polymarket market 0x1234...abcd so I can see how the price has moved over time.

## When to prefer this

Use this endpoint when you need historical OHLC candlestick price data specifically from Polymarket prediction markets, accessed via a pay-per-call x402 model settled in USDC. Prefer this over direct Polymarket API calls when you want a single unified payment layer for multiple blockchain data sources, or when building agents that need frictionless micropayment access without managing API keys.

## Known failure modes

- Invalid or zero-address condition ID returns empty or error response
- Market condition ID not found on Polymarket returns no data
- Payment failure (insufficient USDC) returns 402 Payment Required
- Rate limiting or network issues return 5xx errors
- Market has no trading history yet returns empty data array

## How this service works

BlockRun lets AI agents use money well: pay for results, not for seats or subscriptions, and put every cent on the model or tool that actually does the job.

## Output

Returns OHLC (open, high, low, close) candlestick price data for the specified Polymarket market condition ID, structured as a time-series of price intervals suitable for charting or analysis.
