Simple guide on how to verify Airnode addresses

[wkande]

Context

Jiri has requested a short guide on how a dAPP owner can verify the addresss of an API provider's Airnode.

Suggested Changes

A new guide

Additional Information

For these API providers:

• Coinpaprika: https://coinpaprika.com/
• dxfeed: https://dxfeed.com/
• Finage: https://finage.co.uk/
• Finnhub: https://finnhub.io/
• Kaiko: https://www.kaiko.com/
• NewChangeFX: https://www.newchangefx.com/
• Nodary: https://nodary.io/docs/data-feeds/
• TraderMade: https://tradermade.com/
• twelvedata: https://twelvedata.com/

An example link" https://www.digitalocean.com/community/tools/dns?domain=dxfeed.com#TXT-Records

There is issue in that the provider's used ChainAPI and as such there txt record will use the following:

dxfeed.com | 86400 | chainapi-verification-keys=[0x11030d4f8eB06F958E763C6f8b165D7CDd98DB6C]

So advise the reader to look for chainapi-verification-keys= in the provider's txt records.

Note from Jiri: Hi Warren, I talked with Burak about this and he said, that it's not really correct, but with ChainAPI winding down, we should not really ask them to do any changes. So he suggested we just explain in the docs, that the user should search for: chainapi-verification-keys in order to find the airnode address.

Waiting on Jiri to verify an issue with Kaiko's DNS TXT record. It does not seem to exist.

[wkande]

Jiri has contacted Kaiko and they are getting the txt record added.

Seems like this is done, if so we can close this

[dcroote]

My guess is that this was left open because kaiko didn't have a txt record present. I just checked and that's still the case.

[wkande]

Pretty sure the txt record is all set.

[dcroote]

I don't see it here whereas it is for others, e.g. nodary, here.

@wkande please reread all of the comments

[wkande]

Well it was there when Jiri and I did this. Now I need to track it down again.

Moved here so I will fix this. https://www.digitalocean.com/community/tools/dns?domain=kaiko.io#TXT-Records
