How this service works
Real B2B sourcing and procurement research. Seven paid endpoints on Base mainnet. Payment settlement requires individual human approval by LUMEN. No autonomous purchases.
Output
Returns a JSON object with fields: ok (boolean success), status (string describing quote state), amountUsd (numeric quote in USD), productId (identifier for the sourcing product), receiptId (payment receipt identifier), paymentAuthorizationVerified (boolean), and nextAction (string describing what to do next). Payment settlement and human approval by LUMEN are required before the request is processed.
Example use cases
Pre-validate bulk manufacturing RFQ
“Before I submit a full sourcing request, can you sanity-check this procurement brief on LUMEN B2B: 'Looking to source 10,000 units of custom injection-molded ABS plastic enclosures, 120x80x40mm, in black, with UL94 V-0 flame rating, for Q4 delivery.'”
Check feasibility of specialty chemical sourcing
“Can you validate this sourcing brief for me and get a quote: 'We require 200kg of reagent-grade sodium bicarbonate, USP certified, packaged in 25kg HDPE drums, for delivery to a pharmaceutical facility in New Jersey within 60 days.'”
Assess electronics component procurement brief
“Please run a quick sanity check on this B2B requirement before I go further: 'Need to procure 2,000 units of STM32F4 microcontrollers, LQFP-64 package, from an authorized distributor, with full traceability documentation, shipped within 30 days.'”
Technical details
Endpoint
GEThttps://lumen-zero-x402.lumen-b2b.workers.dev/buy/quote-sanity?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to pre-validate or sanity-check a B2B sourcing or procurement requirement before committing to a full research engagement. It is the appropriate first step when you want a quote and feasibility signal for a sourcing brief. Prefer this over a full procurement research call when the requirement text may be incomplete or you want cost confirmation before proceeding. Note that payment ($7 USDC on Base mainnet) and individual human approval by LUMEN are required — this is not suitable for fully autonomous or high-frequency use cases.
Side effects
- Requirement text too short (<12 chars) or too long (>1200 chars) — validation error
- Payment not settled or unauthorized — request not queued
- Human approval not granted by LUMEN — request stalled
- Malformed or missing 'requirement' query parameter — 400 error
- Network/worker failure on Base mainnet — service unavailable
