Technical details
Endpoint
POSThttps://api.blockchain.com/explorer-gateway-kt/x402/charts/n-transactions?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need structured, time-series transaction-count data specifically for Bitcoin from Blockchain.com's explorer, especially when you want configurable timespans (24h to 3y), rolling average smoothing, and optional metadata — and when you are comfortable paying a small per-call USDC micropayment via the x402 protocol.
Side effects
- Invalid timespan format returns a 400 error
- Unsupported chart format enum value causes a validation error
- Payment not provided or insufficient USDC causes a 402 Payment Required response
- Network timeouts if the blockchain data source is temporarily unavailable
- Empty values array if no transaction data exists for the requested period
