A free API comparison worksheet: which conditions are hardest to verify?

I’m the maker of ClawIsOpen. We’ve added an original, free CSV worksheet to help builders compare an AI API against their own task and account conditions.

The columns cover usage units, reset windows, paid-tier switches, data-use conditions, region eligibility and your test result. Quota cells are intentionally blank: a provider’s headline allowance is not necessarily the limit on your account. No signup, macros or upload back to us.

A suggested first test is ten non-confidential examples, recording usefulness, source support and usage for each. That is a starting method, not a benchmark or a promise of savings.

If you try it, which condition is hardest to find or understand in the provider docs? A specific missing field would help us improve the next version. Please don’t share credentials or private project details.

Prepared with AI assistance; provider references are linked in the guide.
