The first on-chain model router · 400+ models · Robinhood Chain
Ask Logitra.
The first on-chain router built for the people who use it. The first router of its kind on-chain to run on the newest models: Jev, and every model that ships after it, takes its seat in the chamber within minutes of release. Logitra sends each request to the right one. Every answer says whose it was. Your agents pay with a signed tab: no API key, no subscription, no gas per call.
Ask the chamber.
Pick a model, or let Logitra choose. Turn on compare to put the same question to two models side by side. Every answer is stamped with the model that gave it, what it cost and how long it took.
Built for its users. Always current.
Logitra reads the model listing continuously. When a lab ships a new model, it takes a seat in the chamber within ten minutes, priced from its own list price, with no release cycle to wait for. Builders earn from every call their agents make, and holders test free.
Why Logitra: the first router on-chain.
Every model router before this one is a company holding your money and your key. You prepay into their balance, they hold it, and the only proof of what you were charged is their dashboard. Logitra is the first router where the money lives on-chain instead. Your deposit sits in a contract on Robinhood Chain that you can read and withdraw from, not in someone's account. Each request is a signature your agent makes, and settlement is a transaction anyone can check. The 20% a builder earns is paid by the contract at settlement, not by a payout someone remembers to run. Holder access is checked against the chain, not a list.
That changes what you have to trust. Not the operator's bookkeeping: the contract caps what can ever be taken at what you signed. Not a key: there is none to leak, and nothing to rotate. Not a subscription: unspent deposit is yours after a two-day notice. What Logitra runs itself is the routing, and it shows its work on every reply: which model answered, and why it was chosen. That is the whole pitch. Every model in one place, the newest ones the week they ship, and your money where you can see it.
Three promises, on every answer.
The model you named
Your request goes to that model as sent. Nothing swapped, nothing downgraded, no hidden prompt.
Whose answer it was
The answering model's id is in the reply and in Logitra-Model. Auto answers also say which lane and why.
Your words stay yours
Logitra keeps whether a call worked, its tokens and its timing. Never the prompt, never the answer.
More than a key and a balance.
A gateway sells you credit and hands you a key. Logitra gives your agent a chamber of models to work with, and a way to pay for them that it controls.
Hold the coin, sign once, and get 20 free calls a day across the free models, Logitra Auto and base-price models.
Paid calls are signed by your agent's wallet. There is no secret to rotate, paste or lose.
No $5 floor, no bundles. Deposit any amount and every call draws from it.
Unspent deposit is withdrawable, not store credit. The contract enforces it.
Logitra Auto sends code, math and reasoning deep and chat fast, and says why on every reply.
One question, two models, stamped answers. See which earns its price before an agent depends on it.
Every call has a fixed, visible price from the lab's list price. Your agent signs it. No surprise invoice.
Put your app id in the tab and 20% of every settled call goes to you, from the contract.
Every seat.
Every model Logitra relays to, with the lab's own list price and Logitra's price for one call. A call is priced before it runs, so its price is the most it could cost: 2,000 tokens in and 1,024 out at list price, plus 10%. Never below the base price of 0.005 USDG.
How Logitra Auto decides.
It reads your last message before anything is sent. Code, math, multi-step reasoning, structured output and long context go to the deep model, with a larger budget and a reasoning pass. Everything else goes to the fast model. If the deep model fails, the fast one answers and the reply says so. One base price either way.
Pay with a tab, not a key.
No secret to leak, no subscription to cancel. A tab turns every call into a signature, then settles thousands of them at once.
Deposit
Put USDG into the tab contract from any wallet. Withdraw what you have not spent after a two-day notice, so open tabs can settle first.
Sign the running total
Each call carries an EIP-712 signature for the new total: the last one plus that model's price. Replays, skips and forgeries are refused.
Settle in batches
Logitra submits the latest total for every open tab in one call. The contract pays out only the difference, so it can never take more than you signed.
The whole switch is two lines.
Point any OpenAI-compatible client at Logitra and give it the tab's fetch. Messages, model names and streaming work as they do today.
The official coin.
Logitra's coin is launched on Pons, on Robinhood Chain. A plain Pons launch: no staking, no emissions, no extra tokenomics. Holding it lets you test Logitra free, up to 20 calls a day. This page is the only place its contract address is published.
Posted here at launch. Any address you see before then is not Logitra's.
Holders will be able to use the Logitra API from their own code with a key, on set terms that will be published here before keys open.
The contract.
One tab contract, small enough to read in one sitting. The source ships with the repository. Register an app in the console and every tab your agents sign with its id pays you 20% when it settles.
Questions, briefly.
Am I getting the real model?
Yes. A named model gets your request exactly as sent, and the reply carries the model id the provider returned. Nothing is swapped for a cheaper model. Only Logitra Auto and Logitra Free choose for you, and they say what they chose and why.
What is free?
Everyone gets 1 free question a day, counted per IP: no wallet, no signup, no header. It works on Logitra Free, Logitra Auto, the $0 models and every base-price model. Holders of the coin get 20 a day.
How do holders test free?
Connect the wallet that holds the coin and sign one message: no transaction, no gas. Logitra checks the balance on Robinhood Chain and gives that wallet 20 free calls a day on Logitra Free, the $0 models, Logitra Auto and every base-price model. The pass lasts 24 hours.
Can holders use the API with a key?
Coming soon. Holders will get API keys on set terms, published here before keys open. Today, holders test free in the playground and the console, and anyone can call the API with a signed tab.
What is being built next?
Full agent support first: an agent SDK, tool calling, per-agent budgets and holder API keys. After that, holder epochs: a share of settled revenue paid to holders by epoch, weighted by how long they stay. The order and what is live are on the docs. None of it is a promise of returns.
Do you store my prompts?
No. Logitra records whether a call succeeded, how many tokens it used and how long it took. The prompt and the answer are never written anywhere.
How is a call priced?
Before it runs, from the model's list price: 2,000 input tokens plus 1,024 output tokens, plus 10%, rounded up to 0.001 USDG and never below the base price. That fixed price is what your agent signs. Logitra Auto is always the base price.
What do I change in my code?
The base URL and where calls are paid from. With the OpenAI SDK that is baseURL and fetch: tab.fetch. Messages, model names and streaming stay the same.
Is there a subscription or a minimum?
No. Deposit what you like. Unspent deposit is withdrawable after a two-day notice, so tabs you already signed can settle first.
What happens if a model fails?
You are not charged: the tab rolls back. With Logitra Auto, a failed deep model falls back to the fast one and the reply is marked.
The chamber is open.
Ask your first question free as a holder, or open a tab and put every model to work.
