How this service works
Choose which x402 API to build using screened repeat-buyer demand, supplier scarcity, and Base payment evidence.
Output
Returns a structured market intelligence report covering high-demand, low-supply x402 API categories over the last 30 days, including signals derived from repeat-buyer transaction patterns, supplier count and scarcity metrics, and Base blockchain payment evidence to validate real purchasing intent.
Example use cases
Picking next x402 API to ship
“I'm an indie developer trying to decide what x402 API to build next — can you pull the 30-day demand gap report and tell me which niches have lots of repeat buyers but almost no competing suppliers on Base?”
Validating a niche before building
“Before I invest time building a weather-data x402 API, can you check the 30-day demand gap data to see whether that category actually shows strong buyer demand and low supplier coverage?”
Market research for x402 product roadmap
“I'm building a product roadmap for our x402 micro-API platform — pull the latest 30-day demand gaps so I can see which categories have the most underserved repeat buyers and prioritize our builds accordingly.”

Endpoint
GEThttps://x402-demand-gaps.website-findings.workers.dev/api/x402-market/demand-gaps?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need data-driven x402 API opportunity identification backed by real on-chain payment evidence on Base, rather than generic market research or keyword trends. It is purpose-built for developers and product teams deciding which x402 micro-API niche to build into, combining demand-side (repeat buyer) and supply-side (scarcity) signals in a single call. Prefer it over generic API analytics when you specifically want to identify gaps in the x402 pay-per-call ecosystem.
Side effects
- Only the '30d' window value is supported; any other window value will likely return an error or be rejected
- Response schema is loosely typed (object), so field names and structure may vary or be sparse
- Upstream demand/payment data may be stale if the snapshot hasn't refreshed recently
- Endpoint may return empty or minimal gap data if the x402 ecosystem activity is low in the period
