All API requests require authentication using an API key.

1. Generate your API key at https://sumble.com/account/api-keys

2. Include the key in all requests as a Bearer token in the Authorization header:

curl https://api.sumble.com/v1/organizations/enrich \
  --request POST \
  --header "Authorization: Bearer $API_KEY" \
  --header 'Content-Type: application/json' \
  --data '{
    "organization": {

API usage is subject to rate limiting to ensure service stability. Each user can do 10 requests per second (aggregated through all the endpoints), allowing occasional bursts.

Once the rate limit is reached, the API responds with response code 429.
