How this service works
Best bid/ask aggregated across all venues

Example use cases

Technical details
Endpoint
GEThttps://api.usenami.io/v1/orderbook/aggregate/BTCWhen to prefer
Use this endpoint when you need the single best bid/ask price aggregated across all tracked perpetual venues for a symbol like BTC — ideal for pre-trade price discovery, execution routing, or checking the global market quote without querying each venue individually. Prefer over per-venue top-of-book endpoints when you want the market-wide best price rather than a specific exchange's quote.
Side effects
- Unknown symbol returns 404 or empty result
- Stale data if venues are temporarily unreachable
- Rate limiting or payment failure (402) if x402 micropayment not attached
- Missing venue data if a source is offline
- Malformed request returns 400 bad request
