Prepaid or included LLM allowances often expire unused. tokensto.cash lists that spare capacity on the Surplus Intelligence inference market under one house seller: paste a provider key, pick the models, and buyers pay you USDC on Base per request. Auto-priced just under the cheapest healthy seller, never below your cost. Free to list; your key stays encrypted with Surplus and we never hold a balance. Cash out to Revolut, Monzo, Chime, Zelle, Venmo, Cash App, Wise or PayPal at the oracle rate.
Hey Product Hunt, Andrew here, maker of tokensto.cash.
Why it exists: almost every dev and small team I know has LLM credit sitting idle: prepaid top-ups, included allowances, a provider you stopped using. It expires. I wanted that capacity to earn instead.
What it does: paste a provider key (OpenRouter, OpenAI, Anthropic, Gemini, DeepSeek, Groq, Mistral and ~20 more), pick the models, and buyers on the Surplus Intelligence inference market route paid requests through it. You get USDC on Base per request, straight to your own wallet.
What is different:
- One house seller. You never create a Surplus account or sign anything; we hold the seller identity, you hold the payout address.
- Your key goes to Surplus, encrypted per listing. It never touches our database and we never hold a balance.
- A repricer keeps every listing just under the cheapest healthy seller and never below your cost basis, so you are not babysitting prices.
- Cash out to Revolut, Monzo, Chime, Zelle, Venmo, Cash App, Wise or PayPal at the live oracle rate with no spread (same rails as usdctofiat.xyz, our sister product).
- Agents can do the whole loop: there is an open sell-unused-tokens skill for Claude Code and Codex.
Listing is free. What I would love feedback on: the pricing floor logic (never below cost, 1.0x floor for pay-as-you-go keys), which rails or providers you would want next, and whether the first-run flow is clear. Happy to answer anything about the architecture too.
