# Orbio > Orbio provides access to AI inference and is building an onchain CREDIT protocol for agents to acquire, transfer, and activate inference budgets. Contract addresses, the deployed Uniswap route, and wallet-signature gateway support are pending publication. One CREDIT represents $1 of Orbio AI usage. CREDIT and USDG have 6 decimals. Activation permanently burns CREDIT into a nontransferable service balance, not cash. The order book settles in USDG. The planned CREDIT/ORBIO pool has no hook and a 0% LP fee; discounts depend on market prices. ## Private inference - [Incognito setup](https://www.orbio.so/incognito/setup.md): SDK, terminal/MCP and direct API encryption. Read this when the gateway returns private_encryption_required; keep privacy enabled and encrypt locally before retrying. ## CREDIT protocol - [Agent guide — Markdown](https://www.orbio.so/protocol/agents.md): Applications, contract calls, activation, and wallet authentication. Primary concise guide. - [Agent guide — HTML](https://www.orbio.so/protocol/agents): The same content as a readable document. - [Protocol overview](https://www.orbio.so/protocol): Visual introduction to staking ORBIO and using CREDIT. ## Developer platform - [Developer home](https://www.orbio.so/developers): SDK, MCP, models, tools, infrastructure, and OAuth. No token launch required. - [Quickstart](https://www.orbio.so/developers/quickstart): Connect an MCP client or use the TypeScript SDK and API. - [Models and all tools](https://www.orbio.so/developers/reference): Search all providers together, with MCP names, SDK calls, API endpoints, schemas, and inference examples. ## Agent launchpad The agent launchpad is pre-launch. The directory, launch form, management UI and accounting analytics are wired; launching awaits vault deployment. Historical market data is not yet exposed. - [Launchpad](https://www.orbio.so/launchpad): Creator fees, agent stake, CREDIT and metered compute. - [Launchpad white paper](https://www.orbio.so/launchpad/whitepaper): Vision, project revenue, tokenized inference and infrastructure. - [Launchpad white paper, Markdown](https://www.orbio.so/launchpad/whitepaper.md): The same vision paper in agent-readable form. - [Launchpad API docs](https://www.orbio.so/launchpad/docs): Public reads, wallet actions, generated tool schemas and pricing. - [Launchpad API docs, Markdown](https://www.orbio.so/launchpad/docs.md): Agent-readable endpoint and tool reference. ## Resource lifecycle E2B sandboxes, Vercel deployments, Fly.io servers, Supabase databases, and AgentMail inboxes are available through hosted MCP, API, and @orbiodotso/sdk 0.2.1. Each existing API credential or infra-approved MCP connection receives its own isolated scope automatically. No provider OAuth or manual product setup is needed. Resources have explicit budgets and funded lifetimes; renewals are not automatic. - [Resource lifecycle guide](https://www.orbio.so/docs/infrastructure): Setup, connection methods, provider workflows, and searchable API reference. - [Infrastructure Markdown](https://www.orbio.so/docs/infrastructure.md): Full lifecycle, pricing, recovery behavior, and schemas for agents. - [Infrastructure catalogue](https://www.orbio.so/api/v1/infra/tools): Current enabled capabilities and schemas. ## Contract ABIs Public integration subsets verified against source revision cfb44feab098974411347df9734a2937272f5b8d. They contain the methods used in the guide and do not imply deployed addresses. - [Exchange ABI — JSON](https://www.orbio.so/protocol/abi/exchange.json): getQuote, buy, buyAndActivate, feeBps, and MAX_FILLS. Quote.reason is 0 BudgetSpent, 1 LiquidityExhausted, 2 UnitUnaffordable, or 3 WorkLimit. - [CREDIT ABI — JSON](https://www.orbio.so/protocol/abi/credit.json): ERC-20 calls, activate overloads, and the Activated receipt. - [ERC-20 ABI — JSON](https://www.orbio.so/protocol/abi/erc20.json): USDG approvals, allowance, balances, transfers, and decimals. ## Tools An Orbio key buys more than model calls. The same key and balance run web search and scraping, social reads and Robinhood Chain reads, charged after the call at what the provider charged plus 10%. Every tool takes max_cost, in CREDIT, and a call quoted above it is refused before anything runs. - [Tool catalogue — JSON](https://www.orbio.so/api/v1/tools): GET endpoint for request-based tools, their JSON Schemas and prices. Resource tools are published at /api/v1/infra/tools. Call one with POST /api/v1/tools/{name}. - [All tools reference](https://www.orbio.so/developers/reference#tools): Web, blockchain, social, email, sandboxes, deployments, servers, and databases in one searchable reference. - [MCP server](https://www.orbio.so/mcp): The same tools over MCP, for Claude Code, Codex, Cursor and OpenClaw. Signs in over OAuth. ## Sign in with Orbio An app other people use never asks them for an Orbio key. It registers at /developers/apps, sends them to Orbio to sign in (OAuth 2.1 with PKCE, OpenID Connect with the openid scope), and calls the gateway, the tools and MCP with the access token it gets back, on their balance. A registered app may add a fee on top of what they spend, paid to its developer in USDG. - [Sign in with Orbio guide, Markdown](https://www.orbio.so/developers/docs.md): Registering, the authorize and token endpoints, scopes, claims, refresh and the app fee. - [OpenID configuration](https://www.orbio.so/.well-known/openid-configuration): The provider's endpoints and supported scopes. ## Existing inference service - [Orbio](https://www.orbio.so/): AI credit marketplace. - [Model pricing](https://www.orbio.so/pricing): Model catalogue and rates. - [Model catalogue — JSON](https://www.orbio.so/api/v1/models): GET endpoint for model identifiers, output modalities and pricing. Chat models use POST /api/v1/chat/completions with a valid Orbio API key. Decision models such as typesafe/jev-1.13 use POST /api/alpha/decisions with model, state and questions; they do not accept chat messages. Noul, choice and score questions are supported. The same key and balance apply.
