GEThttps://tb2s28fm0h8dkq2t.68r.lambda-web.us-east-1.on.aws/v1/market/categories?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a high-level market overview of the x402 API ecosystem organized by category — ideal for market research, pricing benchmarks, or discovering which API verticals exist. Prefer this over the trending or top-payers endpoints when you want aggregate category-level stats rather than individual API rankings.
