Glassnode enables AI agents to access crypto data with USDC payments
Agents can access Glassnode’s Advanced API without a subscription or API key by paying for individual requests in USDC on Base.
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.
Glassnode’s x402 endpoints mirror its standard Advanced API. The endpoint paths, query parameters and response formats remain the same, with users replacing the standard API subdomain with Glassnode’s x402 subdomain.
A request for an Advanced API metric costs $0.05 in USDC, while requests to Glassnode’s metadata endpoints cost $0.01. Glassnode said pricing and availability may change and clients should confirm the latest amount included in each payment request.
The service uses the HTTP 402 Payment Required response. When an agent calls a Glassnode endpoint without payment, the server returns the amount and payment instructions.
The agent signs the USDC payment and repeats the request with a payment signature before receiving the requested data.
Coinbase describes x402 as an open protocol that turns the HTTP 402 status code into an onchain payment layer for APIs, websites and autonomous agents. The protocol supports programmatic payments without requiring credit cards, user accounts or conventional checkout flows.
Glassnode said all metrics included in its Advanced catalog are available through the integration. Agents can request market, supply, address, exchange, derivatives and onchain indicators using the same parameters supported by the standard API.
Metadata endpoints are also available, allowing agents to discover supported assets, list available metrics and inspect the parameters and time ranges supported by an individual metric before purchasing the data.
The endpoints are listed through Coinbase’s x402 Bazaar, which provides search, structured filters and an MCP interface for agents to discover services that accept x402 payments.
Glassnode labeled the endpoints experimental and said their features, pricing and availability may change. The company recommends its subscription based standard API for production systems.
