## 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 omnicall-pro-ai-completion-claude-gpt-gemini-5f2c8aa1
```

Example prompt: Use the Omnicall Pro endpoint to analyze this contract clause and summarize the key risks — use Claude 4.5 Sonnet: 'The licensor may terminate this agreement with 30 days notice for any reason, with no liability to licensee.'

## When to prefer this

Choose this endpoint when an agent needs a one-off, high-quality completion from a frontier model (Claude 4.5 Sonnet, GPT-5, GPT-4o, or Gemini Pro) without managing API keys or subscriptions. Ideal for tasks requiring advanced reasoning, complex synthesis, or polished drafting billed per-call in USDC on Base or Solana. Prefer over dedicated provider SDKs when keyless, pay-as-you-go access across multiple top-tier models from a single gateway is more convenient.

## Known failure modes

- 402 Payment Required — USDC payment on Base or Solana not attached or insufficient
- Invalid model param — unrecognized ?model value returns an error
- Empty or missing ?input query param — returns 400 bad request
- Model provider outage — upstream Claude/GPT/Gemini service unavailable, returns 503
- Prompt too long — exceeds model context window, returns 413 or truncation error

## How this service works

AI completion, frontier tier — Claude 4.5 Sonnet (default; ?model=gpt-5|gpt-4o|gemini-pro|gemini-3.1-pro). Pay USDC per call, no API key, no signup. For agents that need a frontier model on hard analysis, synthesis, and drafting. See GET /v1/ai/models for the full menu.

## Output

A text completion from the selected frontier model (Claude 4.5 Sonnet by default, or GPT-5, GPT-4o, Gemini-Pro, Gemini-3.1-Pro via ?model param) responding to the provided input prompt. The response contains the model-generated text as the completion payload.
