Example use cases
Tracking x402 ecosystem adoption
“How fast is the x402 npm package growing? Grab the weekly and monthly download numbers for x402 and the other agent-ecosystem packages so I can see the adoption trend.”
Comparing agent framework popularity
“I want to compare how popular LangChain, AgentKit, and MCP are right now — can you fetch their current weekly and monthly npm download counts from the agent ecosystem dataset?”

Technical details
Endpoint
GEThttps://d1x8xrm7jrzkbs.cloudfront.net/data/npm/agent-ecosystem-downloads.jsonWhen to prefer
Choose this endpoint when you need a pre-aggregated, ready-to-use JSON snapshot of npm download counts for the major AI agent ecosystem packages (x402, MCP, AgentKit, LangChain, viem, etc.) without scraping npm yourself. It is ideal for agents that need this data programmatically at low cost ($0.005 USDC per call) with instant settlement via x402 on Base, especially when you want a curated list of agent-relevant packages rather than arbitrary npm package lookups.
Side effects
- Payment not settled in USDC on Base — 402 Payment Required returned before data is delivered
- Invalid or missing format parameter — may return error or default behavior
- CloudFront origin timeout or cache miss — transient 5xx error
- Stale data if npm registry upstream has not refreshed — counts may lag by hours
- Insufficient USDC balance in agent wallet — payment fails and no data returned
