What Inception Mercury API does
Inception provides OpenAI-compatible API access to Mercury diffusion language models. Its setup instructions say each new API key comes with 10 million free tokens, while the Free-plan section on the same Models page lists 100 million. An earlier owner-confirmed account check also observed both amounts. The provider does not explain how the figures relate, so check the balance shown in the account before estimating usage.

FreeAIList verdict
Inception offers a potentially generous API trial, but its own current page presents different amounts in the setup instructions and plan summary. Treat the account dashboard as authoritative and do not budget against 100 million tokens without confirming the balance.
Paid plans: Usage after the starter allowance is billed at the current model-specific input, cached-input, and output token rates.
