Our API uses API Tokens for authentication, ensuring secure and efficient access to your workspace data. Users can create API tokens in their API Tokens Settings page, with the flexibility to set them with or without expiration dates, based on your requirements. API tokens are workspace-scoped, meaning they are tied to a specific workspace. Within this workspace the api token can manage all resources of the workspace and those of all projects of the workspace. When making requests for project resources, each request must include a Fastgen-Project header with the project id as the value, in order for the request to be correctly authenticated. The API token are sent as Authorization Bearer Token header like so: 
FASTGEN_URL="https://app.fastgen.ai"
API_KEY="__YOUR_API_KEY__"

curl --location --request POST "$FASTGEN_URL/v1/..." \
  --header "Authorization: Bearer $API_KEY" \
  --header 'Content-Type: application/json' \
  --data-raw '...'
