04 / GOOD TO KNOW
Frequently asked
questions.
Is PromptCore only for Claude?
We’re starting with Claude. Available models and enabled routes are listed in the console.
How is usage charged?
Each successful API call deducts its model’s USD price: $0.007 for Haiku/Sonnet, $0.0075 for Opus, or $0.01 for Fable. A conversation can use several calls.
How do wallet top-ups work?
Choose a USDT network and request a payment quote in the console. Send the exact amount using the specified network. USD credit is added after payment verification. Online top-ups support $15–$1,000, subject to network minimums.
Can I mix models?
Yes. Packages add USD wallet credit rather than a model-specific allowance. Your balance covers usage across enabled models at their respective call prices.
Are token references guaranteed?
No. They reflect the supplier’s threshold of 1 billion tokens per 2,400 calls. They are informational, not included token allowances or a promise of tokens used per request.
Which API integrations are supported?
See Getting started in the console for supported endpoints, request examples, and current limitations.
Are local demo purchases real payments?
No. Local demo recharges add simulated credit with no cash value. Production USDT payments use the payment quote and verification flow.
Is this an official Anthropic service?
No. PromptCore is an independent service, not affiliated with or endorsed by Anthropic.
