Automated certainty for any business.
Lumen Sieve takes just a business name and location, finds every page that actually points to it, reconciles what they say, and hands you back one verified profile via API — with a confidence score on every field.

}The challenge
Business data is broken.
Fragmented reality
Corporate data lives in silos — directories, listings, and social profiles. None of them talk to each other, and half of them are years out of date.
AI hallucinations
Language models guess business details when they can't find them — leading to silent failures downstream in any workflow that trusts the answer.
Truth reconciliation engine
Lumen Sieve bridges the gap between chaotic signals and a verified profile in three stages.
01 · Discovery
Scattered data
A name and a location is all we start with. Every page that actually points to that business gets found.
02 · Reconciliation
Cross-checked
What each source says is compared against every other source. Agreement builds confidence; conflicts get resolved, never ignored.
03 · Delivery
Verified profile
One record comes out the other end, delivered via API — every field scored, every field sourced, nothing guessed.
Ask Lumen Sieve
Query a resolved profile directly in plain English. Grounded in that profile — never a guess.
Suggestion
“What's their return policy?”
Suggestion
“How many employees do they have?”
Their own site states a 30-day parts warranty on installed parts. No general returns policy is published beyond that.
I don't have that information for this business.
Why Lumen Sieve
Verified sourcing
We don’t just aggregate — we audit. Every field is traced back to a primary, corroborating source.
Field-level confidence
Get a probability score for every field. Programmatically decide when to trust data and when to review it.
Production-ready API
A clean REST API with predictable JSON, idempotent lookups, and per-field responses built to be called, not just browsed.
Built for developers, trusted by teams.
Lumen Sieve is API-first. Everything on this page runs on the same endpoints you'd call from your own systems.
Ground AI agents
Give an agent verified facts about a real business instead of letting it guess.
Enrich your CRM
Populate lead records with verified, source-attributed facts on every call.
const lumen = require('@lumen/sdk'); // Resolve a business profile const profile = await lumen.resolve({ name: 'Two Rivers Auto Care', location: 'Nairobi, KE', }); console.log(profile.status); // > "verified"

Frequently asked
What happens if a business publishes conflicting information?
Lumen Sieve cross-checks every source it finds. When sources disagree, the conflict is resolved deliberately and reflected in that field’s confidence score — never silently averaged or guessed.
What if Lumen Sieve doesn’t know something?
It says so. An unpublished or unverifiable field is left unknown rather than filled with a plausible-sounding guess — the same rule Ask Lumen Sieve follows when you ask it a question directly.
Is this a one-time lookup or can I keep data current?
Both — resolve a profile on demand, or call the API from your own systems whenever you need the latest read on a business.
Is there a free trial?
Yes — the Free plan includes 50 lifetime lookups, no credit card required. Paid plans start once you need more volume; see the Pricing page for details.
Which countries and businesses does Lumen Sieve cover?
Any business, anywhere — resolution runs on the name and location you give it rather than a fixed list of pre-indexed businesses or countries.
What if a field in my profile is wrong?
Submit a correction through the API or dashboard. It’s reviewed and factored into that business’s future profile generations.
How is data protected?
TLS 1.2+ everywhere, API keys stored as one-way hashes, and AES-256 encryption at rest — the same standard applied to Lumen Sieve’s own infrastructure.
