Check Credits

The Check Credits endpoint is useful for checking how many credits are left for a specific pubkey. To ensure privacy, credit information is going to be provided only after authentication has been fulfilled.

Check Credits with Nostr

1. Connect to our relay wss://relay.vertexlab.io
2. Perform a successful NIP-42 Authentication with one or more pubkeys.
3. Fetch kind 22243 to get the credit info associated to all authed pubkeys.

["REQ", "<sub_id>", { "kinds": [22243] } ]

Check Credits with the API

1. Send a GET request to https://relay.vertexlab.io/api/v1/credits with NIP-98 Authentication Header for exactly one pubkey.
2. Read the event from the response’s body.

Response

In both cases, the response will be a Nostr event.
