Technical details
Endpoint
GEThttps://claw402.ai/api/v1/coinank/rank/oi-vs-market-capWhen to prefer
Use this endpoint when you need to identify which crypto assets have the highest or lowest open interest relative to their market capitalization — useful for spotting over-leveraged or under-leveraged markets. Prefer this over raw OI endpoints when the market-cap-normalized view is needed for cross-asset comparison. No API key or registration required — only a USDC wallet via x402 protocol.
Side effects
- Empty data array returned if no results match query parameters
- Invalid sortBy or sortType values may return unfiltered or error response
- Payment failure (402) if USDC wallet has insufficient balance
- Rate limiting or timeout if upstream CoinAnk data is unavailable
- Non-zero code field in response body indicating upstream data error
