# Frodo Agent

> One private chat for every major AI model, below list price. The first 20 messages are free with no account; after that a wallet pays with CREDIT, one token for one dollar of inference. Frodo Agent runs on the Orbio protocol on Robinhood Chain and relays chat through the Orbio gateway.

## Start here

Frodo Agent needs no account. The first 20 messages in a browser are paid by Frodo Agent. After that the visitor connects a wallet, buys CREDIT on the Orbio Exchange book in the Console, and the wallet signs one fixed line ("Orbio API key · chain 4663 · epoch 0") to make its key. CREDIT activated to that wallet is the balance the chat spends, at each model's list price, charged after each request. Chats are saved in the visitor's browser only.

- [How Frodo Agent works](https://frodoagent.com/docs): Free messages, privacy modes (Private, Zero retention, Open), what stays outside the seal, where chats live, temporary chats, choosing a model, credit and pricing, the wallet key and common questions.
- [Chat](https://frodoagent.com/chat): The chat itself. Add ?model=<id> to open it on a model from the catalogue.
- [Pricing](https://frodoagent.com/pricing): Every model with its list price and its price paid with CREDIT from the book, per million tokens, plus the private models and their hosts.
- [Console](https://frodoagent.com/app): Buy CREDIT on the book (activate to the wallet key or keep as tokens), make the wallet key, try any model, sell spare CREDIT, stake ORBIO. Every step is a transaction the wallet signs.

## Live data

- [Model catalogue, JSON](https://frodoagent.com/api/catalog): GET, public. { models, private, belowListPercent, allIn }. Each model has id, name, lab, input, output (list USD per million tokens), context, vision, tools and reasoning; private models also name their host (Phala or NEAR AI). Paid with CREDIT from the book, a model costs list times allIn.
- [Protocol stats, JSON](https://frodoagent.com/api/stats): GET, public. Tokens served, requests, tool calls, stakers, staked ORBIO, agents, purchases and the book's asks. Big integers are strings; null fields mean the source is down.

## Private models

Private picks open-weight models that run inside an attested enclave at Phala or NEAR AI. The enclave providers' attestation is what makes them private. Frodo Agent relays these requests through the Orbio gateway and does not seal messages in the browser or check attestation evidence itself.

## CREDIT

CREDIT is live on Robinhood Chain (chain 4663) and bridged to Ethereum and Solana. One CREDIT is one dollar of usage. CREDIT and USDG have 6 decimals. Activation permanently burns CREDIT into a nontransferable service balance, not cash. The book settles in USDG; discounts depend on market prices.

- [Protocol](https://frodoagent.com/protocol): CREDIT, the agent launchpad, building on one key, and the contract list.
- [CREDIT for agents](https://www.orbio.so/protocol/agents.md): Orbio's guide for an agent with its own wallet: buy CREDIT, activate it, sign a wallet key and make the first request.

## Developers

The API lives at Orbio. The Frodo Agent wallet key is an Orbio wallet key, so it works there directly. Base URL https://api.orbio.so/api/v1 (OpenAI-compatible), MCP endpoint https://api.orbio.so/api/mcp, SDK `npm install @orbiodotso/sdk`.

- [Developers](https://frodoagent.com/developers): Connect an agent, give it tools, and the one-key toolkit in brief.
- [Quickstart](https://www.orbio.so/developers/quickstart): Connect an MCP client, or use the TypeScript SDK or the API, with an account key or a wallet key.
- [Authentication](https://www.orbio.so/developers/authentication.md): Orbio's credentials, the wallet key, and every refusal code.
- [TypeScript SDK](https://github.com/orbioso/orbio-sdk#readme): @orbiodotso/sdk on npm: models, tools, the balance, buying and activating CREDIT, and the wallet key.
- [Models and tools reference](https://www.orbio.so/developers/reference): Every model and tool with MCP names, SDK calls, API endpoints, schemas and prices.

## Contracts (Robinhood Chain, chain 4663)

Frodo Agent deploys no contracts of its own. These are the Orbio protocol's.
