# Xava Inference

> Hold $INFX, earn free AI credits. One OpenAI-compatible API key for text, image, video, audio and embedding models from many providers, at list prices, with cash back on every spend. Requests on models with rewards fund a token buyback you pick: up to 0.5% of paid spend, 2% at Pro, 5% at Elite, capped at the request margin. Prepaid credit backed by USDC in a public reserve (card, or USDC on Solana and save 5%). Agents can also pay per media request with x402 (USDC on Solana), no account needed.

Base URL: https://xavainf.com/v1 (OpenAI-compatible; send `Authorization: Bearer <API key>`). Model ids are `provider/model`, e.g. `openai/gpt-5.4`, `meta/llama-3.1-8b-instruct-fp8`.

## In plain language

- What is Xava Inference? One API key for text, image, video, audio and embedding models from many model makers, at the model makers' own list prices. It is OpenAI-compatible: change the base URL and the key.
- How is it priced? Everyone pays each model's list price, the model maker's own price, per unit (per 1M tokens, per image, per second of video): https://xavainf.com/models. Holders don't pay a different price; they earn more cash back.
- What is Reward Status? Every account starts as Noob (list prices, 0.5% buyback). Hold 1,337 $INFX in a linked Solana wallet for Pro (2% buyback); add 1,337 XAVA on a linked Avalanche wallet (with 1,337 $INFX) for Elite (5% buyback). Everyone pays the same list price; a higher status means more cash back.
- How do I pay? Prepaid credit, no subscription: by card at the posted price, or with USDC on Solana and save 5% ($100 of credit costs $105 by card or $100 in USDC). Credit is not redeemable for cash.
- What is the buyback token? Every account splits its buyback between $INFX (the default) and any eligible Solana token. Your Reward Status sets the rate whatever the split: up to 0.5% of paid spend at Noob, 2% at Pro, 5% at Elite, on models with rewards. It comes out of our margin and is capped at that margin, never added to the price. Buybacks are executed on-chain and published.
- What rewards are there? Holding $INFX earns AI credits: $INFX LP fees fund them (the USDC that reaches the vault after the treasury's deduction), credited to holders every hour by time-weighted holdings, automatically, with no claim (hold at least 1,337 $INFX on the hourly average). Holder credits are backed 1:1 by USDC and expire after 45 days unused; affiliate and promotional credits after 365 days unused; credits you buy with USDC or card don't expire. When you buy inference, up to 5% comes back to you in USDC, $INFX or another supported token you choose. Our margin goes 10% to the protocol fee and 90% buys $INFX: 54% of the margin to holders, 27% burned, 9% permanently locked by the team. Details: https://xavainf.com/rewards
- Does $INFX have a transfer tax? Yes, 1% of every $INFX transfer: 0.6% is burned and 0.4% is permanently locked by the team.
- Do you keep my prompts? No. We never store your prompts or replies; we keep billing details only: model, amount and time. Zero data retention end to end on models marked ZDR supported; uploaded references and generated files auto-delete after 24 hours. On a model marked ZDR supported, neither we nor the model provider store your prompts or outputs; on other models the model provider's own retention policy applies.
- How long are generated files kept? Images, video and audio are served from this site and deleted 24 hours after creation: every media response carries `expires_at` (unix seconds), and an expired link answers 410 Gone. Download what you want to keep.
- Can I give a model my own image, video or audio? Yes: pass an https URL in the model's reference parameter, or upload the file (`POST /v1/uploads`) and pass the upload id. Uploads are charged as "Reference storage" (from $0.001 a file) and deleted 24 hours after upload.
- How do coding agents use it? Install the plugin or add the remote MCP server (https://xavainf.com/agents), then sign in once in the browser: the agent spends the account balance within the monthly cap picked at consent. No wallet or private key is ever needed on the user's machine.
- Can agents pay without an account? Only agents that already have a wallet provider with spending policies (e.g. a hosted or custodial agent wallet): image, video and audio can be paid per request in USDC on Solana with x402 (https://xavainf.com/docs/x402).
