Estimates use each tier's typical per-message cost. Actual billing is usage-based — see “How billing works” below.

HOW BILLING WORKS

Fair by design.
Pay for what you actually use.

1 · Estimate

Each model shows a typical per-message estimate (e.g. ~19 attach). That amount is held when you hit send.

2 · Settle

When the response completes, we compute the message's real cost and adjust the hold — up or down — automatically.

3 · Floor

Every message costs at least 5 attach ($0.005) — even on the cheapest models. That's the only minimum.

4 · Refund on failure

If a request fails or a stream breaks, the full hold is refunded. You only pay for delivered responses.

Short messages routinely settle below the estimate. Long, complex messages on premium models can settle above it — the estimate is a typical midpoint, not a cap.

THE MODEL CHAOS

See the problem?
There are too many models.

This is exactly why ⚡ Strap Mode exists. Let us pick the right one for each message.

Every new account receives 1,000 attach ($1.00 service-value) — enough for ~110 budget or ~20 premium messages. Try any model before you buy.

Table shows typical estimates. You're billed for actual usage: a small hold is placed when you send, then settled to the message's real cost — short messages cost less than the estimate. Minimum 5 attach ($0.005) per message. Prices include platform fee. 100+ models available through the gateway.

FAQ

Questions?
Straight answers.

What is attach?

attach is Botstrapp.ai's platform service credit: 1 attach = $0.001, so 1,000 attach = $1.00. It's closed-loop — non-transferable between users, no cash value — and it never expires while your account is active (Terms § 5).

Why did my message cost less (or more) than the badge amount?

The badge is a typical estimate, not a fixed price. That amount is held when you send, then settled to the message's actual cost when the response completes. Short messages settle below the estimate; long messages on premium models can settle above it — the estimate is a midpoint, not a cap.

Is there a minimum charge?

Yes — 5 attach ($0.005) per message, even on the cheapest models. That's the only minimum.

What happens if a request fails?

The full hold is refunded automatically. Failed requests and broken streams cost nothing — you only pay for delivered responses.

What's included in the price?

Each message settles to the provider's actual cost plus a 35% platform fee. The markup is public — every response carries it in the X-Botstrapp-Markup-Rate header, alongside raw-cost, final-cost, and token-count headers.

Can I get a refund?

Yes. The unused portion of a purchase can be refunded within 14 days, paid back in USD (Terms § 5.3).

Can I use my own API keys?

Yes. With BYOK (bring your own key), messages sent through your own provider API key cost 60% of the standard per-message attach price.

Why are marketplace packs priced in USD?

Paid memory packs are billed in USD only, never in attach — a compliance choice that keeps attach a pure service credit. Sellers pay a 15% commission if they keep earnings as platform credit, or 20% when cashing out in USD via Stripe Connect.

Can I sell my own memory pack?

Yes. In Chat → Store, create a pack (your expertise as reusable AI context), set a price ($3–99) or keep it free, and submit it for review. Paid packs require connecting a seller account first (Account → Seller, powered by Stripe). Your share lands in your Stripe balance on every sale and is paid out to your bank once it reaches the payout threshold.

What about refunds or card disputes on marketplace purchases?

Contact support first — defective or misdescribed packs are refundable within 14 days (Terms § 5.7), which is faster than a bank dispute. Your card statement shows BOTSTRAPP.AI, so charges are easy to recognize. If a sale is refunded or a dispute is lost, the seller's share is reversed automatically.

Is the 🧙 Philosopher (Homo Dei) free?

Yes — if you're patient. Select the BotStrApp.Ai (local) model and Philosopher answers are completely free: they run on our own hardware, which takes a few minutes per answer (a live counter shows progress). Pick Router or any cloud model instead and answers arrive in seconds, billed as a normal character turn. Patience is free, speed is paid — same knowledge either way.

What happens when my balance runs out?

The API returns HTTP 402 and responses are blocked until you top up; in Chat, models lock. Buy any pack and you're back instantly — packs are one-time, no subscription.
