How this service works
Eckari is the machine-native utility layer for capabilities agents do not already have. Every route is a provider-neutral capability with channel pricing for Eckari account keys and accountless x402 payment.
Output
Returns a JSON object containing the company name, last filed accounts details (type, period start/end, made-up-to date), next accounts due date and period, accounting reference date (day/month), and a flag indicating whether accounts are overdue. Metadata includes source (Companies House), API version, freshness indicator, and capability identifier.
Example use cases
Due diligence on a UK supplier
“I'm vetting a potential UK supplier and need to check their accounts compliance — can you pull up the accounts filing status for company number 05678901? I want to know if they're overdue and when their last accounts were filed.”
Monitoring a competitor's filing deadlines
“Can you check when Marks and Spencer, UK company number 00214436, needs to file their next accounts and what period the last filing covered?”
Investor screening for accounts overdue risk
“I'm looking at a UK company with number 07654321 before investing — can you check whether their accounts filings are up to date and when the next one is due?”
Technical details
Endpoint
GEThttps://api.eckari.com/v1/companies/uk/%7Bcompany_number%7D/accountsWhen to prefer
Choose this endpoint when you specifically need UK company accounts filing status, deadlines, and accounting period data sourced live from Companies House. Prefer this over general company search endpoints when the goal is compliance checking, due diligence on filing timeliness, or surfacing accounting reference dates — not when you need officer lists, registered address, or company profile data (use sibling endpoints for those).
Side effects
- Invalid or non-existent company number returns an error or empty data
- Company dissolved or struck off may return no accounts information
- Rate limiting or payment failure via x402 results in 402 Payment Required
- Malformed company number format returns validation error
- Occasionally stale data if Companies House registry update is delayed
