## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability blackbobs-ai-ai-chat-6a617441 -d '<json body>'
```

Example prompt: Ask the BlackBobs.ai AI Chat endpoint: 'What are the main differences between transformer and RNN architectures in machine learning?' and return the response — pay the $0.15 USDC per-call fee via x402 on Base.

## When to prefer this

Choose this endpoint when you need pay-per-call AI chat without a subscription, want billing in USDC on Base via x402, or are building lightweight agent workflows where cost per query matters and you want micropayment-native AI access.
