How this service works
Evidence-backed company facts and current company information for company enrichment and company verification, with field-level sources, freshness and explicit conflicts.
Output
A JSON object containing the resolved canonical company entity (name, domain, aliases, confidence), per-field results each with a value, list of source URLs with excerpts and retrieval timestamps, source agreement ratio, and confidence score. Also includes a list of unresolved fields (with reasons), detected conflicts between sources, overall response status (PARTIAL or FULL), a list of all sources consulted, and a response hash for deduplication.
Example use cases
Due diligence fact-check on a startup
“I'm evaluating a potential investment in a company called 'Cohere AI' — can you pull their legal name, headquarters, last reported funding, and employee count with source citations and flag any data conflicts? Only use facts from the last 90 days.”
Enriching a CRM record with verified data
“I have a lead from stripe.com in our CRM and I need to enrich it with their legal name, industry, and headquarters. Make sure to include where each fact came from and how fresh the data is.”
Competitive intelligence research
“For my competitor analysis on openai.com, fetch their founding year, key executives, and industry classification — I want to see all the sources consulted and any disagreements between them, using data no older than 30 days.”
Technical details
Endpoint
POSThttps://mercator-entity-evidence.fly.dev/v1/entity-evidenceWhen to prefer
Choose this endpoint when you need structured company facts with explicit provenance — not just a value, but which source it came from, how fresh it is, and whether sources agree. Ideal for due diligence pipelines, CRM enrichment, compliance workflows, or any agent that must show its work when reporting company data. Prefer this over plain web search when you need machine-readable, conflict-aware, timestamped facts rather than raw text.
Side effects
- Company cannot be resolved — ambiguous name with no domain provided, returns low-confidence entity or error
- Requested fields not available in any source — field appears in 'unresolved' list with reason
- Data older than max_age_days — field may be omitted or returned with staleness warning
- Source conflicts detected but no consensus — conflict returned explicitly with differing values
- Rate limit or payment failure — 402 response if x402 payment not attached
- Invalid field enum values — validation error rejecting unknown field names
