How this service works
Agent-payments market snapshot, measured by us: x402 Bazaar listings, sellers, 30-day paid calls, concentration, how many sellers have real buyers, registry dead rates, wallet shelf sizes. Dated JSON.
Output
A dated JSON object (as_of field with ISO date) containing x402 Bazaar metrics: total origins, listing count, 30-day paid call volume across all listings, market concentration measure, ratio of sellers with real buyers, registry dead rates, and wallet shelf size distribution.
Example use cases
Sizing the x402 agent market
“Give me the current AgentCheck snapshot — I want to know how many listings and sellers are on the x402 Bazaar right now and how many paid calls happened in the last 30 days.”
Assessing marketplace health before launching a service
“Before I list my agent service on the x402 Bazaar, pull me the AgentCheck market snapshot so I can see how many sellers have real buyers versus dead listings and what wallet shelf sizes look like.”
Tracking market concentration over time
“Fetch the latest AgentCheck snapshot and tell me how concentrated the x402 market is — are a handful of sellers capturing most of the paid calls, or is it spread out?”
Technical details
Endpoint
GEThttps://agentcheck-kohl.vercel.app/snapshot?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a high-level, pre-computed market health summary of the x402 agent-payments ecosystem without querying raw Bazaar or registry data yourself. Prefer it for dashboards, competitive analysis, or due-diligence checks on the x402 marketplace as a whole. Use the sibling CSV endpoint instead if you need per-seller granularity.
Side effects
- Snapshot data may be stale if AgentCheck's measurement pipeline has not run recently
- HTTP 402 if payment header is missing or malformed (x402 paywall)
- Service unavailable if Vercel deployment is down
- Incomplete metrics if upstream data sources (Bazaar, x402scan) are unreachable during measurement
