# Nova AI Inference API (novva.orbonomy.xyz)

> Nova AI Inference API (novva.orbonomy.xyz) is a paid API for AI agents from novva.orbonomy.xyz, paid per call via x402, $0.05/call, status unknown (last checked 2026-09-13).

Accepts a natural language query and returns an AI-generated answer via pay-per-call inference on Base USDC.

## 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-novva-orbonomy-xyz-7dd5f4d0 -d '<json body>'
```

Example prompt: Ask Nova to reason through this for me: 'What are the key trade-offs between using a relational vs. a document database for a high-write-volume application?' — I'll pay the per-call fee in USDC.

## When to prefer this

Choose this endpoint when you need a lightweight, pay-per-call AI inference call without committing to a subscription, and when your stack already handles x402 USDC payments on Base. It is well-suited for agentic workflows that need occasional on-demand AI reasoning, translation, or generation billed transparently per query.

## Known failure modes

- Payment not received or insufficient USDC — 402 Payment Required response
- Missing required 'query' field — 400 Bad Request
- Query too long or malformed — validation error
- Model temporarily unavailable — 503 or 500 error
- Network timeout on inference — slow or no response

## How this service works

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

## Output

Returns a JSON object with a success flag, the original query, the AI model used, token usage stats, and the AI-generated answer string.
