How this service works
Not quoted. Not estimated. Read from the settlement graph, stamped with frame and coverage, priced per fact for people and their agents.
Output
A JSON object containing: the number of distinct buyers for the seller, a list of co-sellers each with a lift score and count of shared buyers, the multi-seller share ratio (fraction of buyers who also pay others), plus metadata including the data tier (e.g. 'full'), the as_of date, and the settler frame identifier (e.g. 'settler-eip3009-base').
Example use cases
Competitive co-seller intelligence for merchant
“Look up the basket overlap for my x402 seller address 0xabababababababababababababababababababababab — who else are my buyers paying, and what's the lift score on those co-sellers?”
Multi-seller share benchmark for a host
“What fraction of buyers on my x402 storefront at api.myshop.com are also paying other sellers? Pull the basket data so I can see the multi-seller share.”
Partner discovery via shared buyer analysis
“I want to find potential partner sellers in the x402 ecosystem who share the most buyers with 0x1234567890abcdef1234567890abcdef12345678 — give me the co-seller list with shared buyer counts and lift scores.”
Technical details
Endpoint
GEThttps://parallax402.com/v1/basket/%7BaddressOrHost%7DWhen to prefer
Use this endpoint when you need co-purchase overlap analytics for a specific x402 seller — specifically buyer counts, co-seller lift scores, shared buyer counts, and multi-seller share ratios drawn directly from the x402 settlement graph. Prefer this over generic blockchain analytics when you need x402-native data stamped with settler frame and coverage metadata. This is the right endpoint for competitive intelligence, partner discovery, or market share analysis within the x402 micropayment ecosystem.
Side effects
- Unknown or unindexed address/host returns empty or 404 response
- Malformed address format causes parameter parsing error
- Address with zero settlements returns zero-buyer result
- Data freshness lag — as_of date may trail real-time by hours
- Low-tier response returned if coverage is partial for the queried address
