How this service works
x402 supply census — who is live, in what category, at what price. The full public discovery index (~14.8k resources) normalised into per-category price percentiles and per-origin catalogues, so you can price against the median instead of the loudest listing. Crossed with the half that is not public: which agent client stacks actually crawl a live origin, and therefore which ones will find your endpoint once you ship it. HOW TO CALL: GET /api/demand/competitors?category=market-data&limit=40 PARAMETERS: category — optional filter (market-data, crypto-onchain, trading-signal, ai-inference, media-gen, web-search, enrichment, social, messaging, storage, other) limit — origins returned, 1-100 (default 40) RESPONSE: catalog.by_category[] price min/p25/median/p75/max, catalog.top_origins[], and ecosystems_crawling[] observed over 7 days. PRICING: $0.05 per call.
Output
Returns a JSON object containing: catalog.by_category[] with price statistics (min, p25, median, p75, max) for the requested category; catalog.top_origins[] listing the leading endpoints; and ecosystems_crawling[] identifying which AI agent client stacks have been observed crawling those origins over the past 7 days.
Example use cases
Pricing a new x402 API competitively
“I'm about to launch a new x402 market-data endpoint and want to know where the median price sits — can you pull the price percentiles for the market-data category so I don't underprice or overprice compared to the 40 top origins?”
Checking crawler reach before launch
“Before I ship my new x402 enrichment API, can you tell me which AI agent client stacks are actively crawling enrichment origins right now, so I know which ecosystems will actually discover it?”
Competitive landscape scan for ai-inference APIs
“Give me a competitive overview of the ai-inference category in the x402 ecosystem — top origins, price range from min to max, and which crawlers have been active there over the past week. Show me up to 50 results.”
Technical details
Endpoint
GEThttps://market2000.xyz/api/demand/competitorsWhen to prefer
Choose this endpoint when you need to benchmark your x402 API pricing against real market data, understand which AI agent crawlers are active in a category, or build a competitive map of live endpoints in the x402 ecosystem. It is especially valuable pre-launch for pricing strategy and post-launch for distribution auditing. Prefer it over generic API directories when you specifically need x402-native supply data with price percentiles and crawler coverage.
