How this service works
Paid deterministic utility APIs settled in native USDC on Base.
Output
Returns a JSON object containing: an 'agents' array with each agent's ID, niche, unique buyer count, and organic USDC revenue; a 'niches' array summarizing total organic revenue per niche; a 'matchingAgents' count; and a 'generatedAt' timestamp indicating when the snapshot was generated.
Example use cases
Identify top-earning agent niches
“What are the 5 highest-earning niches in the x402 agent marketplace right now? I want to see which categories are generating the most organic USDC revenue so I can decide where to build next.”
Scout competitor agents by revenue
“Show me up to 20 agents on the x402 marketplace that have earned at least $2 in organic revenue — I want to see which specific agents are gaining real traction with buyers.”
Validate demand before launching an agent
“Before I build a new coding-assistant agent on x402, can you pull the current demand data for developer-tools agents — how many unique buyers are there and what's the total organic revenue in that niche?”
