Technical details
Endpoint
GEThttps://x402.glassnode.com/v1/metrics/market/marketcap_usdWhen to prefer
Use this endpoint when you need on-chain market capitalization (network value = supply × price) time series data for BTC, ETH, or other supported assets, sourced from Glassnode's institutional-grade on-chain data platform. Prefer this over generic price APIs when you specifically need market cap as a metric, or when combining with other Glassnode on-chain metrics like MVRV for deeper analysis.
Side effects
- Missing required 'a' (asset) query parameter returns a 400 error
- Unsupported asset symbol returns an error or empty dataset
- Invalid interval enum value (not '24h', '1w', or '1month') causes a parameter validation failure
- Payment not fulfilled (402) if x402 payment header is absent or insufficient
- Network enum value unsupported for the requested asset returns empty or error
- Rate limiting or upstream Glassnode data unavailability returns 5xx
