# Sell unused tokens Turn leftover provider credits into USDC on [tokensto.cash](https://tokensto.cash). Seller front door for [Surplus Intelligence](https://www.surplusintelligence.ai). Sister of [usdctofiat.xyz](https://usdctofiat.xyz). ## Completion Done when the models appear on `/sell` as live (or cooling), and the user knows cash-out is Create / Orders / Send. ## When not to - Buying inference — that is the Surplus buyer side. - Opening a Surplus seller account. Users never SIWE with Surplus. - The user has not confirmed their provider terms allow resale, transfer, brokering, or monetization of unused API credits or capacity. Stop and send them to the provider terms first. - Google Vertex without a URL already supported by Surplus. Vertex is not in the picker. ## Do this 1. Open https://tokensto.cash/start and sign in (Privy wallet). Evidence: the connect-key screen, not a marketing page. 2. Confirm the user has checked the provider account terms. If they have not, stop. 3. Pick the provider that owns the leftover credits. Featured: Venice, Capminal, OpenRouter, OpenAI, Anthropic, Gemini, DeepSeek, Groq, Mistral. More sits behind "More". Capminal daily $CAPU credit is **Included**. Use **Other** only for a URL Surplus already supports; OpenAI compatibility alone is not enough. 4. Paste the key into the field. **Never echo, log, commit, or store it.** Surplus probes it and keeps it encrypted per listing. tokensto.cash does not persist keys. 5. Wait for the probe.
