# Xava Inference

> Hold $XINF, earn free AI credits. One OpenAI-compatible API key for text, image, video, audio and embedding models from many providers, at list prices (Elite prices for $XINF and XAVA holders). Every prompt buys back a token you pick: 0.5% of each spend, up to 2% with Elite Reward Status. Prepaid credit backed by USDC in a public reserve (card, or USDC on Solana for 5% less). Agents can also pay per media request with x402 (USDC on Solana), no account needed.

Base URL: https://www.zinf.ai/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, per unit (per 1M tokens, per image, per second of video). Elite accounts pay the model's Elite price instead: https://www.zinf.ai/models
- What is Reward Status? Every account starts as Noob. Hold or stake 1,337 XAVA on Avalanche, or hold 1,337,000 $XINF on Solana, in a wallet linked to your account to reach Elite: Elite prices on every model and a bigger buyback.
- 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 picks one: $XINF by default, or any eligible Solana token. 0.5% of every spend buys it back (Elite: 2% for $XINF, 1.5% for a custom token), out of our margin, never on top of the price. Buybacks are executed on-chain and published.
- What rewards are there? $XINF is paired with USDC. 3% Hold Rewards Tax: every $XINF transfer pays holders in USDC. Our 33% lock earns its share in USDC; an on-chain autobuy share (0-70%, set by a public controller multisig) buys $XINF back into the lock, and the rest becomes AI credits for holders (hold at least 1,337 $XINF on the hourly average). Claim within 30 days; earned and promotional credits expire after 365 days unused, and credits you buy don't expire; burned credits go 50% to XAVA stakers and 50% to $XINF buybacks locked forever. Details: https://www.zinf.ai/rewards
- What is the 3% Hold Rewards Tax? 3% of every $XINF transfer, wallet to wallet included, is paid to holders in USDC by the launchpad (StonkFun), automatically, with nothing to claim.
- 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://www.zinf.ai/agents), then sign in once in the browser: the agent spends the account balance within the daily 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://www.zinf.ai/docs/x402).
