One key. 341 models. Paid in crypto.

Top up a balance from your wallet and spend it on whatever model does the job. No plan, no card, no monthly floor you have to grow into.

/Or just use the API

It looks like this

$ curl kytro.xyz/v1/chat/completions \ -H "Authorization: Bearer kytro_live_8f2a…" \ -d '{"model":"claude-sonnet-5","messages":[…]}' { "content": "…", "usage": { "prompt_tokens": 812, "completion_tokens": 337 }, "kytro": { "credits_charged": 7.4129 } }

Same request shape as the OpenAI API, so anything already pointed at that works here by changing two settings. The cost comes back attached to the response. You never have to go look it up.

What it costs

A dollar buys 1,000 credits.

That is the whole pricing model. Each model has a published rate and you are charged per request. Below is what the ones people actually use cost. Everything else is on the rate card.

Model	Good for	Per request
gemini-3.7-flash	Bulk work where quality matters less than volume	1.3 cr
claude-sonnet-5	The default. Most people should start here	7.4 cr
gpt-5.6-sol	Tool calling and anything agentic	7.4 cr
claude-opus-5	Long reasoning. Expensive, and usually overkill	18 cr
flux-2-pro	Stills, priced per image not per token	60 cr
kling-2.6	Video. Budget for it	290 cr

Honest note. For most jobs Sonnet beats Opus on price and you will not notice the difference. We list Opus because sometimes you will.

Recently

What we shipped recently.

Wallet linking is live. Connect Phantom or Solflare and the holder discount applies to the account automatically.

Streaming now cancels the upstream call when you disconnect. You stop paying mid-answer instead of at the end.

Added glm-5.3 and kimi-k3-fast. Both are cheap and better than expected at long context.

Per-key daily caps. A runaway retry loop can no longer drain a balance while you sleep.

Reasoning tokens are reported separately. On thinking models they were most of the bill and nobody could see them.

Before you sign up

Things it does not do yet.

Better you read this now than find out later.

✕No team accounts. One balance, one owner. Shared budgets are on the list, not built.

✕Credit cannot be withdrawn. Once it is on the account it is spend-only. Top up in amounts you will actually use.

✕156 of the 341 models are catalogue only. They are listed and priced but not wired to the workspace yet.

✕Fine-tuning is not supported and is not planned this year.

✕If a provider goes down, we go down for that model. We route around it where a close substitute exists, but not always.

$KYTRO

There is a token. It does one thing.

Hold it and your platform fee drops, 25% off for every 1% of supply, to zero at 4%. That is the entire utility. It pays no yield, it is not a share of anything, and we would rather you ignored it than bought it expecting otherwise.

One billion supply on Solana, mint and freeze authority revoked at creation. Full tokenomics.
