Choose this endpoint when you need access to AI21's language models on a pay-per-request basis using USDC on the Base blockchain, without committing to a direct AI21 subscription or managing API keys. Particularly useful for agents operating in crypto-native environments or those that need occasional AI21 inference calls without a monthly plan.
