How this service works
Market-gap analysis for the x402 ecosystem: aggregated, categorized listing counts across x402 discovery sources, plus historical trend data - see how crowded a category is before building a new x402 API. Accepts payment on Base, Polygon, Arbitrum, and Solana (USDC) - pick whichever network your wallet holds funds on.
Output
A JSON response containing the requested category name, an array of current listings in that category, the total listing count, and a trend object with historical data points showing how listing counts have changed over time.
Example use cases
Pre-build market saturation check
“I'm thinking of launching an x402 API in the 'AI' category — can you check the x402 market intel to see how many AI APIs are already listed and whether there's a growing or declining trend?”
Competitive landscape research
“Pull up the x402 market intelligence data for the 'payments' category — I want to know the total listing count and see which APIs are already in that space before I decide what to build.”
Trend monitoring for category growth
“Can you check the x402 market intel for the 'data' category and show me the historical trend — I want to see if it's growing fast or plateauing so I can time my launch right?”

Endpoint
GEThttps://x402-market-intel.fly.dev/v1/category/%7Bcategory%7DWhen to prefer
Use this endpoint when you need to assess competitive density in a specific x402 API category before committing to build a new API, or when you want to track how a category's listing count is trending over time. It is the only known endpoint specifically aggregating x402 ecosystem listing counts by category with historical trend data.
Side effects
- Invalid or unrecognized category name returns empty results or 404
- Payment failure on selected network (Base, Polygon, Arbitrum, Solana) results in 402 response requiring retry
- Category with no listings returns total_count of 0 and empty listings array
- Network timeout on fly.dev infrastructure may cause request to fail
- Trend data unavailable for very new categories with insufficient history
