How Billing Works

  1. Top up your wallet — minimum $5, no expiry on credits
  2. Make API requests — credits deducted per request based on token usage
  3. Monitor usage — real-time dashboard shows spend per model and API key
  4. Set spending controls — optional monthly spend cap per key

Rate limit: 60 requests per minute (RPM) per API key.

Cost Calculator

# Estimate cost for a chat completion
input_tokens = 1000
output_tokens = 500

input_cost  = (input_tokens  / 1_000_000) * 0.10  # $0.000100
output_cost = (output_tokens / 1_000_000) * 0.20  # $0.000100
total       = input_cost + output_cost             # $0.000200

print(f"Cost: ${total:.6f}")
