# Nova AI Inference API — Analyze Endpoint

> Nova AI Inference API — Analyze Endpoint is a paid API for AI agents from noa.orbonomy.xyz, paid per call via x402, $0.1/call, status unknown (last checked 2026-09-14).

Runs pay-per-call AI inference on text, images, or audio, returning model-generated analysis, chat responses, translations, or reasoning via USDC micropayment on Base.

## Facts

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 nova-ai-inference-api-analyze-endpoint-6d57fef0 -d '<json body>'
```

Example prompt: Can you analyze this image and tell me what's in it? Here's the URL: https://example.com/photo.jpg — also explain what the main subject appears to be doing.

## When to prefer this

Choose this endpoint when you need flexible, pay-per-call AI inference (chat, reasoning, translation, image or audio analysis) without a subscription, and you want to pay in USDC on Base via x402 micropayment. It supports multimodal inputs (text + image URL + audio URL) in a single call, making it suitable for agents that need to combine modalities. Prefer it over subscription-based AI APIs when cost control per call matters, or when integrating with crypto-native payment flows.

## Known failure modes

- Payment not included or insufficient USDC: 402 Payment Required — agent must attach x402 payment header
- Prompt field missing: 400 Bad Request — 'prompt' is a required field
- Invalid image or audio URL: model may fail to fetch or parse the media, returning an error or degraded output
- Model inference timeout: slow or large inputs may cause request timeout
- Unsupported media format at image_url or audio_url: inference may fail or return empty content
- Network error reaching noa.orbonomy.xyz: connection refused or DNS failure

## How this service works

Pay-per-call AI inference. Chat, reason, translate, analyze, generate. USDC on Base.

## Output

Returns a JSON object with a 'data' field containing the AI-generated content string, the model name used, and usage stats; plus a 'meta' field with price charged, endpoint name, flags for whether audio/image were included, and a timestamp. Also includes a top-level 'success' boolean.
