Is a cheap Claude API legitimate? Six checks before you send money

Price alone tells you nothing about which one you are looking at. These are checks you can run yourself — including against us, and we fail one of them.

Price alone tells you nothing about which one you are looking at. These are checks you can run yourself — including against us.

Six checks

  1. Is there an identifiable operator and terms you can read?
  2. Do list-price comparisons cite dated provider sources?
  3. Can you reconcile usage blocks against charges?
  4. Does a canary suggest the model you asked for?
  5. Are errors typed HTTP failures rather than 200-with-failure-body?
  6. Is prepaid credit sized to a pilot, not a leap of faith?

We expect you to run these against Supesonic. Start from relays explained and canary testing.
