Hi Subscan -- My company runs a collator node on Moonriver, and twice in the past day I've set identity on chain, and the Staking page displays the company name for a few hours and then disappears. The info is still on chain, and on my individual account page the data fields exc. Name are still showing.

Hi, I'm having a very strange problem.

I'm doing this query:

curl -X POST -H "x-api-key: YOUR_KEY" -H "Content-Type: application/json" https://polkadot.api.subscan.io/api/scan/staking/validator -d '{"stash":"16SpacegeUTft9v3ts27CEC3tJaxgvE4uZeCctThFH3Vb24p"}'

but when I do with an other validator, I get data null:

curl -X POST -H "x-api-key: YOUR_KEY" -H "Content-Type: application/json" https://polkadot.api.subscan.io/api/scan/staking/validator -d '{"stash":"1sh6y8SMuseeuxn8JyW4eUHbJrLevi7ASH1TJQqb3DFjAYe"}'

can someone explain me what I'm missing...

I'm getting this:

{"code":0,"message":"Success","generated_at":1634552068,"data":{"info":null}}

Hi, I call this interface.

curl -X POST 'https://rococo.api.subscan.io/api/scan/parachain/contributes' \
  --header 'Content-Type: application/json' \
  --header 'X-API-Key: YOUR_KEY' \
  --data-raw '{
    "page": 0,
    "row": 2
  }'

And get these results, What does the memo field mean? How is this field obtained from the chain?

Hi, I want to use the who parameter to call the api/scan/parachain/contributes interface to query the user's corresponding contribution.

I use the who parameter to send the request and cannot find the extrinsic, but I can get the corresponding extrinsic without the who parameter.

1. Request with who
   curl --location --request POST 'https://kusama.api.subscan.io/api/scan/parachain/contributes'

--header 'Content-Type: text/plain'

--data-raw '{ "fund_id": "2087-37", "row": 100, "page": 0, "from_history": true, "who": "DrCFRy8rE75gGv7WydEtoGaL2AR6ccU3cJChdiaf3XUwSvH" }'

result:

{
    "code": 0,
    "message": "Success",
    "generated_at": 1634693265,
    "data": {
        "contributes": null,
        "count": 0
    }
