## 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 x402-ai-apis-pokemon-auth-chat-completion-db4cf349 -d '<json body>'
```

Example prompt: Chat with the Pokemon-auth x402 AI endpoint: send the message history '[{"role":"user","content":"What is Pikachu?"}]' with a max of 200 tokens, temperature 0.7, and streaming disabled.

## When to prefer this

Choose this endpoint when you need a pay-per-call AI chat completion API gated by x402 USDC micropayments, especially in automated agent pipelines where you want fine-grained per-request payment control without a subscription. The Pokemon-auth variant may offer a specific authentication or access tier distinct from other sibling endpoints on the same host.

## Known failure modes

- Payment not provided or insufficient USDC balance — 402 Payment Required response
- Messages array missing or malformed — 400 Bad Request
- Temperature or max_tokens out of acceptable range — 400 validation error
- Upstream AI model timeout — 503 Service Unavailable
- x402 facilitator or payment network unavailable — payment processing failure
