Example prompt: Can you pull the historical cumulative trading volume for Polymarket token 0x1234abcd so I can see how activity has built up over time on that market?

## When to prefer this

Choose this endpoint when you need historical cumulative volume data specifically for a Polymarket prediction market token. It is ideal for time-series analysis of trading activity, liquidity assessment, or detecting volume anomalies. Prefer this over general DeFi volume endpoints when the target is a specific Polymarket market identified by token ID.

## Known failure modes

- Invalid or non-existent token_id returns an error or empty dataset
- Market not found if the token_id does not correspond to an active or archived Polymarket market
- Payment failure if the x402 micropayment of $0.0085 USDC is not properly handled
- Rate limiting or upstream Polymarket API unavailability causing delayed or failed responses
- Malformed token_id format causing a 400-level error
