Before you post

underlist / 01

Read this before anything goes out.

Do

Post the image or the video with its tweet, as is. Edit the wording if you like, never the facts.
Link to undrlst.com. Tag @smaaartio when you quote a post.
Quote a discount only if the live book shows it on the day you post, net of the 5% card fee.
Answer questions with the ready replies; when you don't know, say so and ask the team.

Don't

No investment, yield, APY, returns or passive-income wording. Credits are product access.
No token, ticker or chart: the product doesn't mention one.
No made-up numbers: no volumes, users or savings we can't show.
No other brand's logo or visual, and no price comparison with a named competitor.

Voice

Short sentences, plain words.
Lowercase underlist, always.
Say what it does, not how great it is.
One idea per post.

(01) Launch

220/280Post

underlist post 01 of 14, Launch: “Every model, under list.”

Meet underlist. Every top AI model, for less. One API key for Claude, GPT, Gemini and everything else on OpenRouter, paid with credits that cost less than list price. Switching takes two lines. undrlst.com

(02) How it works

180/280Post

underlist post 02 of 14, How it works: “Three steps to a smaller bill.”

underlist in three steps: 1. Sign in and create your key. 2. Top up credits by card, from $5. 3. Point your SDK at api.undrlst.com. Same models, same SDK, a smaller bill.

(03) How you save

251/280Post

underlist post 03 of 14, How you save: “Deepest discount, first.”

How you save: 1 credit = $1 of usage at the model's list price. You buy credits from a public book of discounted listings. Your order takes the cheapest ones first and only pays list price for whatever's left. Same model. Same tokens. Smaller bill.

(04) Same model

38/280Post

underlist post 04 of 14, Same model: “Same tokens. Less spent.”

Same model. Same answer. Smaller bill.

(05) Migration

114/280Post

underlist post 05 of 14, Migration: “Two lines. Nothing else changes.”

Switching to underlist: base_url = "https://api.undrlst.com/v1" api_key = "sk-smaaart-…" That's the whole migration.

(06) Privacy

246/280Post

underlist post 06 of 14, Privacy: “Relayed, never stored.”

You get the model you ask for. No quiet swaps, no fallback to something cheaper. Requests only go to zero-data-retention endpoints, and we never store your prompts or answers. Billing needs model, tokens, cost and latency, so that's all we keep.

(07) In numbers

156/280Post

underlist post 07 of 14, In numbers: “underlist, in numbers.”

underlist in six numbers: 1 credit = $1 of usage 2 lines to switch $5 minimum top-up $2,000 maximum per card payment 1 key for every model 0 prompts stored

(08) Our promises

116/280Post

underlist post 08 of 14, Our promises: “What we won't do.”

What underlist won't do: – keep your prompts – swap the model you picked – hide a fee – show you numbers we made up

(09) Your dashboard

134/280Post

underlist post 09 of 14, Your dashboard: “Every request, and what it cost.”

Your dashboard shows every request: tokens in and out, what it cost, and how much latency underlist added, measured on your own calls.

(10) Your key

101/280Post

underlist post 10 of 14, Your key: “Rotate the key. Keep the balance.”

One key per account. Rotate it and the old one stops on the next request. Your balance doesn't move.

(11) Top up

201/280Post

underlist post 11 of 14, Top up: “Top up from $5. Pay per token.”

Top up by card, anywhere from $5 to $2,000. Credits land as soon as the payment clears. Your quote shows the discount on every tier. Card payments add a 5% platform fee, on the receipt before you pay.

Only add a discount figure if it matches the live book (npm run book -- list) on the day you post.

(12) FAQ

192/280Post

underlist post 12 of 14, FAQ: “Is it a wrapper? It's a relay. Your request goes to the exact model you named, the response keeps the provider's own id, and you pay the real cost in credits.”

Is underlist a wrapper? It's a relay. Your request goes to the exact model you named through OpenRouter, the response keeps the provider's own id, and we bill the real cost from your credits.

(13) FAQ

157/280Post

underlist post 13 of 14, FAQ: “Where's the discount from? A public book of credits listed below $1. Your order takes the cheapest offers first, and never pays more than list price.”

Where does the discount come from? A public book of credits listed below $1. Your order takes the cheapest offers first and never pays more than list price.

Answers for the questions that come up.

Text only. If a question isn't here, don't improvise a number: ask the team.

Is it a wrapper?

167/280

It's a relay. Your request goes to the exact model you named through OpenRouter, the response keeps the provider's own id, and we bill the real cost from your credits.

Where's the discount from?

121/280

A public book of credits listed below $1. Your order takes the cheapest offers first and never pays more than list price.

NoteCredits are product access, never money. Keep it that way.

Can you read my prompts?

134/280

We relay them and never write them anywhere. Routing is zero-data-retention only. We keep model, tokens, cost and latency for billing.

Which models?

94/280

Everything on OpenRouter, by its usual id, like anthropic/claude-sonnet-5 or openai/gpt-6-sol.

Can I pay in crypto?

128/280

The card checkout already takes crypto, Apple Pay and Google Pay. Paying in USDG on Robinhood Chain comes with the onchain book.

Is there a subscription?

99/280

No. You buy credits when you need them, from $5, and spend them per token. No seat, no monthly fee.

How do I switch?

130/280

Two lines: set the base URL to https://api.undrlst.com/v1 and use your underlist key. Any OpenAI- or OpenRouter-compatible SDK works.
