Nansen Launches Pay-Per-Call Model, Enabling Instant On-Chain Data Access via x402

Odaily News Nansen has announced the introduction of a pay-per-call model, optimizing on-chain data access based on the x402 protocol and PayAI infrastructure. This model allows users to instantly query wallet data, fund flows, and "smart money" signals through USDC micropayments, eliminating the need for subscriptions, approvals, or API keys. The system automates the "request-billing-payment-return" process based on the HTTP 402 mechanism, supporting autonomous calls and payments by AI agents.

Nansen stated that the new model already covers its entire API ecosystem, with basic data queries priced at approximately $0.01 per call and advanced signals at around $0.05, supporting settlement on the Base and Solana networks. (Crowdfundinsider)
