How this service works
Pay-per-call UK company, property and crypto market data for AI agents via x402. Official sources, no signup, no API keys, failed calls never charged.
Output
A JSON object containing: a verdict enum ('likely_available', 'caution_similar_names_exist', or 'likely_unavailable'), an array of exactMatches (companies with the same name), an array of closeMatches (companies with similar names including their name, status, company number, and similarity score), and the original proposedName. This allows the agent to immediately assess registration risk.
Example use cases
Pre-registration name clearance check
“I'm about to form a new UK company and want to call it 'Apex Renewables Limited' — can you check if that name is free and whether there are any close matches I should worry about?”
Startup brand conflict screening
“We're launching a fintech startup and thinking of naming it 'ClearFlow Payments Ltd' — please check the UK company register and tell me if anything similar already exists.”
Agent-assisted company formation workflow
“Before I proceed with filing, check whether 'Northern Oak Consulting Ltd' is likely available on the UK Companies House register and flag any dissolved or active companies with similar names.”
