ERC-8004 allows AI agents to have on-chain identities and rate each other. To analyze how many of these ratings are from someone who paid the agent, data was gathered from Base, a blockchain platform. On October 14, 2026, at 10:50 UTC, the Base Reputation Registry was joined with stablecoin payments indexed. Out of 514,096 feedback entries on Base, only 728 (0.14%) were from raters who had previously paid the agent they rated.
The raters behind these 728 ratings numbered 17, and the agents rated totaled 64. Among the payments, 107 settlements occurred, with an average of $0.03 per payment. Only 3 of the settlements were x402, which indicates a specific type of payment transaction. The data on these 728 grounded ratings, along with their corresponding payments, is available as a CSV file on GitHub under a Creative Commons Attribution 4.0 license.
This data provides insight into the relationship between payments and ratings for AI agents on Base.
