Frequently asked questions

Does IncorpSignal replace the official Companies House register?

No. Companies House remains the authoritative public register. IncorpSignal adds bounded search, linking, monitoring and decision-support context with routes back to source records.

Can I try the workflow before subscribing?

Yes. A free account includes a daily search allowance. Paid plans add unlimited search, monitoring, enrichment and REST API access.

Can software and AI agents use the same data?

Yes. The developer interface at https://incorpsignal.com/developers documents the TypeScript SDK, REST API, 26 MCP tools and explicit x402 pay-per-call products.
