API Keys

In order to obtain higher limits on the Hub API use, apply for an API Key.
We want to make sure that we limit the risk of the API downtime and provide a reliable and continuous service and therefore we decided to implement API Keys to make sure that the requests are coming from genuine users.
You can use the same API key for different Snapshot APIs. Limits are counted individually per each API Service.


Currently, we are in a transition period. During the next two months until July 30th, the limits for keyless access to the API will not change:
🔓 No API Key: 60 requests per 20 seconds.
🔑 With the API Key: 2 million requests per month.
After September 12th, the limits will be updated to:
🔓 No API Key: 100 requests per minute.
🔑 With the API Key: 2 million requests per month.
If you are getting close to 2M requests a month please reach out to our team directly on Discord by creating a new ticket in the #helpdesk-tickets channel.

How can I get an API Key?

1. Apply via the request form

If you haven’t already please fill in the below form or submit it via the direct link.

API Key Request Form

2. Wait 72 hours

We will review your submission and whitelist the address you provided in the form.
After 72 hours have passed you can continue with the next steps. If you get any errors while generating the key, please create a ticket in the #helpdesk-tickets channel.

3. Generate the API Key

After your address has been whitelisted go to and connect your wallet using the account you provided in the submission form above.

a) Sign the message with keyword generateKey:

b) Copy the signature and run the below curl command.
curl --location '' \
--header 'accept: application/json' \
--header 'content-type: application/json' \
--data '{
"jsonrpc": "2.0",
"method": "generate_key",
"params": {
"id": "123456789"
Make sure to use the signature hash from step 5 in the sig param, do not paste the entire response after signing the message. As an example:
"method": "generate_key",
"params": {
"sig": "0x85bcabdeb3b43131364d21b32f8c74124d155009fc9d6d40901b4b725f23e0ac632808ebb00f3569bf875ded07b61ac5163ebe757b0897278ab276cdc982e3001c"
You will receive the API Key as a response of the curl request. Make sure to store it securely.

How to structure the query with my key?

The only change you need to make is to add the API Key in the headers of your request:
curl '' \
-H 'content-type: application/json' \
-H 'x-api-key: <YOUR-API-KEY>' \
--data-raw '{"query":"\n{\n space(id:\"snapshot.dcl.eth\"){\n id\n name\n members\n}\n}","variables":null}' \
Alternatively, you can use the apiKey param in the query string with your key as a value:
curl '<YOUR_API_KEY>' \
-H 'content-type: application/json' \
--data-raw '{"query":"\n{\n space(id:\"snapshot.dcl.eth\"){\n id\n name\n members\n}\n}","variables":null}' \
If you are using the GraphQL interface you need to provide your key in the headers tab:
