Technical details
Endpoint
GEThttps://x402-farm.vercel.app/v1/us/companyWhen to prefer
Use this endpoint when you need a quick, pay-per-call lookup of a US public company's SEC CIK identifier or exchange listing without setting up an account or managing API keys. Ideal for AI agents that occasionally need to resolve company identifiers for SEC EDGAR research, financial data enrichment, or regulatory compliance checks. Prefer this over direct EDGAR scraping when you want a clean JSON response with no parsing overhead.
Side effects
- Company not found in SEC EDGAR returns empty or error response
- Private or foreign companies not registered with SEC may return no results
- Ambiguous company names may return incorrect or unexpected matches
- Network or service unavailability returns HTTP error
- Micropayment failure via x402 protocol blocks the request
