# Deck > Deck gives AI agents authenticated access to any website without an API. Deck's browser agents sign in as your users, fetch data, fill out forms, and make payments, then return structured JSON to your product — at any scale. Teams use Deck to pull bills and statements from utility and vendor portals, file claims and applications on government and payer sites, pay invoices on supplier and utility payment pages, and update the card on file at merchants. Deck stores your users' credentials in an encrypted vault, handles sign-in, MFA, and captchas, runs tasks on demand, on a schedule, or chained into workflows, and records every run with screenshots and agent reasoning. If a person can do it in a browser, a Deck agent can do it too. Every agent session runs in a fully isolated virtual machine with credential vaulting, full audit trails, human-in-the-loop approvals, a kill switch, and session replay. Deck is SOC 2 Type II and PCI DSS Level 1, and used by teams at companies including Sunrun, BILT, Entrata, Wander, and EY. ## Docs - [Documentation](https://docs.deck.co): Product docs for building, running, and observing computer use agents - [API Reference](https://docs.deck.co/api-reference): REST API and SDK reference for agents, connections, and tasks - [Developer resources](https://deck.co/developers): Named landing pages for OpenAPI, auth, webhooks, MCP, CLI, and errors - [OpenAPI](https://deck.co/openapi.json): Versioned REST description with typed 4xx/5xx error schemas - [API catalog](https://deck.co/.well-known/api-catalog): RFC 9727 catalog pointing at the v2 API - [Error handling](https://docs.deck.co/api/errors): Machine-readable error codes, messages, and request IDs - [Versioning and deprecation](https://docs.deck.co/api/api-status-and-changes): `/v2` path versioning and Sunset/Deprecation policy - [Sitemap](https://deck.co/sitemap.xml): All public pages - [Full content for LLMs](https://deck.co/llms-full.txt): Extended Deck reference including comparisons, FAQ, and pricing detail - [Console](https://console.deck.co): Sign in to build and run agents ## Developer resources - [Deck developer resources](https://deck.co/developers): Index of API docs, OpenAPI spec, auth, webhooks, MCP, CLI, and rate limits - [Deck documentation](https://deck.co/docs): Product docs index (canonical guides at https://docs.deck.co) - [Deck API documentation](https://docs.deck.co/api-reference): REST API and SDK reference for agents, connections, and tasks - [Deck OpenAPI spec](https://deck.co/openapi): OpenAPI 3.1 for the Deck v2 REST API — also at https://deck.co/openapi.json - [Deck API catalog](https://deck.co/.well-known/api-catalog): RFC 9727 machine-readable catalog of the Deck API and MCP server - [Deck API authentication](https://deck.co/api-auth): Bearer token auth, base URL `https://api.deck.co/v2`, request format - [Deck API errors](https://deck.co/errors): JSON error model with `type`, `code`, `message`, `resolution`, and `request_id` - [Deck error schema](https://deck.co/errors.json): Typed JSON error contract for agents - [Deck webhooks](https://deck.co/webhooks): Event destinations, deliveries, and webhook best practices - [Deck API versioning](https://docs.deck.co/api/api-status-and-changes): `/v1/` vs `/v2/` path versioning and deprecation policy - [Deck rate limits](https://deck.co/rate-limits): 200 requests / 10 seconds;
