CashBoard prices agent data by the call over x402

CashBoard says it has opened its market signals to AI agents through a hosted MCP server and plain HTTP routes, using x402 for payment. Its November 8 post advertises a price of 1 to 3 cents in USDC per tool call and names Base among the supported payment routes. The provider describes the offering as live on mainnet.

This is a specific supplier announcement, not independent evidence of customer demand or data accuracy. A publicly described payment endpoint does not show how often buyers return, whether a signal is fresh enough for their task or whether service delivery meets their needs. Those are separate questions from whether software can authorize a small payment.

The useful design pattern is to put the purchase boundary around one clearly defined unit of data. An agent buyer needs a spending limit, a clear response contract and a rule for handling missing or stale inputs. Per-call pricing can make experimentation easier, but the decision to buy should depend on the value of the returned information, not merely on the small size of each charge.
