How this service works
Composite due-diligence brief: vet + business + pulse + market spikes header for one payTo. Paid upgrade after /v1/vet — replaces separate pulse/business Bazaar rows.
Output
A composite JSON brief containing: trust verdict (organic/concentrated/fragile/solo/opaque), settlement data, business profile details, live market pulse metrics ($/hr, tx/hr vs 24h baseline), and recent market spike signals — all for the specified payTo address on Base.
Example use cases
Example prompt
“Run a full due-diligence brief on the x402 payTo address 0xAbC123...def on Base — I want the trust verdict, business profile, pulse, and any market spikes all in one report.”
Technical details
Endpoint
GEThttps://ylk.one/v1/x402/brief?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a comprehensive, single-call due-diligence package on an x402 payTo address and want to avoid making separate calls to /v1/vet, pulse, and business endpoints. It is the paid upgrade path from /v1/vet and is ideal when you need trust verdict, business context, and live market signals together. Prefer sibling endpoints (ylk-vet, ylk-spikes, ylk-rails) when you only need one dimension of data and want to minimize cost.
Side effects
- Missing or invalid payTo address (parameter 'a' not provided or not a valid 0x address) — returns 400 or error response
- Address not found in x402 settlement data — may return empty or sparse brief
- Payment failure (x402 $0.08 USDC not settled) — returns 402 Payment Required
- Address on wrong chain (not Base) — results may be incomplete or inapplicable
- Rate limiting or upstream data lag — returns 429 or stale data warning
