Glassnode Brings Pay-Per-Request Onchain Data to Coinbase's x402

Glassnode has launched pay per request access to its onchain and crypto market data through Coinbase's x402 payment protocol. The integration allows AI agents and developers to retrieve Glassnode Advanced API metrics without an API key or subscription.

Each request is authorized through a USDC payment on Base, with a cost of $0.05 for Advanced API metrics and $0.01 for metadata endpoints. Pricing and availability may change, so clients should confirm the latest amount included in each payment request.

The service uses the HTTP 402 Payment Required response, where agents call Glassnode endpoints without payment, and the server returns the amount and payment instructions. Agents then sign the USDC payment and repeat the request with a payment signature before receiving the requested data.
