The UK company register kept by Companies House, read through its Public Data API: who a company is, who runs and controls it, what it has filed, what is secured against it and whether it is insolvent, and the people disqualified from running one. This Airnode signs what it obtained from Companies House, so the attestation says where the data came from rather than that Companies House stands behind this relay. Officer and PSC records are personal data.
Every response carries an EIP-191 signature from the Airnode that served it, so the data can be attributed back to its source rather than trusted on reputation.
Served at https://airnode-companies-house.fly.dev/. Each operation is reached the way the provider documents it, under https://airnode-companies-house.fly.dev/api, and answers with the provider's own response and the attestation in headers, so a client built against the provider works unchanged. The same operations are also served as one JSON envelope on POST /, which the HTTP interface covers. Every request below can be sent from this page, and what comes back is verified right here in the browser.
GET/
Returns the machine-readable documentation this page is rendered from. Free, and everything an agent needs.
ANY/api/…
The provider's own requests, one per operation, forwarded as they are. The provider's response comes back untouched, with the attestation in the X-Airnode headers.
Verify the response
Paste a response to verify it originates from the current Airnode: the JSON a POST / answers with, or a passthrough response with its headers, as curl --include prints it.
