How this service works
What x402 API should I build? The demand gap finder runs up to 150 Bazaar searches phrased the way buyer agents phrase tasks and ranks the unmet demand: tasks whose top results are weak (no listings, few payers, thin descriptions or a poor fit), with the evidence for each. Public Bazaar data only, joined with measured repeat demand per category.
Output
Returns a list of demand gaps, each with a task description, a 0-100 opportunity score, a verdict of 'open' (no meaningful supply) or 'weak' (poor-quality supply exists), a count of repeat buyer searches in the last 30 days for that category, and a headline summarizing the total number of underserved buyer searches and the biggest opportunity found.
Example use cases
Finding a profitable niche to build
“I want to launch a new paid API on the x402 marketplace. Can you use Agoranome to find which categories have the most open demand gaps so I know what to build first?”
Scoping competition in a specific topic
“I'm thinking about publishing a geospatial x402 API. Can you check the Agoranome gap finder for the 'geospatial' topic and tell me if that category has weak supply or strong competition?”
Weekly marketplace opportunity review
“Can you pull the latest demand gap report from Agoranome so I can see which buyer searches are coming up empty or finding weak results — I want to prioritize my API roadmap for the next sprint?”
Technical details
Endpoint
GEThttps://api.agoranome.com/v1/seller/gaps?utm_source=zero.xyzWhen to prefer
Use this endpoint when you are an x402 API seller (or prospective seller) wanting to identify unserved or underserved demand in the agent API marketplace before committing to building or listing a new API. It is specifically designed for the x402 / Bazaar ecosystem and surfaces real buyer search signal, making it more actionable than generic market research. Prefer this over generic keyword trend tools when you need marketplace-native demand data tied directly to what AI agent buyers are actually paying to find.
Side effects
- No topic match found — returns empty gaps array if the specified topic has no buyer search history
- Overly broad topic string may return many low-score gaps with little actionable signal
- Payment failure (x402 USDC settlement not completed) — request blocked before processing
- Service unavailable — API returns 5xx if marketplace index is being refreshed
- Topic string exceeds 80-character limit — request rejected with validation error
