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 confirming payment and queued research, including a product ID, receipt ID, payment authorization status, amount paid in USD, and a next-action field indicating what happens after human review and settlement. The actual tender scan results are delivered after individual human approval by LUMEN.
Example use cases

Technical details
Endpoint
GEThttps://lumen-zero-x402.lumen-b2b.workers.dev/buy/tender-scan?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need real B2B tender and procurement opportunity research for a specific sourcing requirement, and you accept a pay-per-request model ($9 USDC) with human-in-the-loop result approval. Best suited for procurement teams or sourcing agents that need curated tender matches rather than automated, real-time database queries. Not suitable for use cases requiring instant autonomous results or high-frequency automated scanning.
Side effects
- Payment not settled — request is not queued without verified USDC settlement on Base mainnet
- Sourcing brief too short (under 12 characters) or too long (over 1200 characters) — validation error
- Brief contains confidential or sensitive procurement details that violate submission guidelines
- No matching tenders found for the given sourcing brief — empty results after review
- Human approval delay — results may not be immediate due to mandatory manual review step
- Network or worker error from Cloudflare Workers infrastructure
