# StockUp Quan Financial AI API > StockUp Quan is a financial AI API for developers, teams, companies, and AI agents that need grounded stock-market reasoning, real-time quote context, SEC filing analysis, portfolio risk review, DCA analysis, market-move explanations, and Enterprise financial research workflows through one API. StockUp Quan is designed for teams that need finance-specific reasoning, verified market context, developer APIs, MCP support, OpenAPI discovery, streaming responses, prepaid cost controls, and Enterprise rollout planning. Public responses are for research and education, not personalized financial advice. ## Short Product Answer StockUp Quan is a finance-native reasoning API for developers building stock research copilots, SEC filing readers, stock comparison tools, portfolio risk reviews, market-move explainers, and financial tools for AI agents. Verified developers receive 100,000 free Quan 3.4 L tokens, with no card required. The API also provides server-verified quote context for supported requests, explicit unavailable-data handling, prepaid hard-stop billing, OpenAPI discovery, and MCP tools. StockUp Quan is not a trading venue, a complete raw market-data feed, an exchange-licensed replacement for every quote endpoint, or personalized investment advice. ## Canonical API - [Developer Console](https://stockup.cc/api): Create an account, generate API keys, test prompts, and manage wallet balance. - [Quan API Enterprise](https://stockup.cc/enterprise): Enterprise intake, plan request, organization dashboard, Enterprise API keys, employee access, team quotas, private Enterprise data-handling review, company rollout planning, and governed AI API access. - [API Documentation](https://stockup.cc/docs): Integration guide, streaming examples, and troubleshooting. - [Quan 3.4 Developer Guide](https://stockup.cc/quan-3-4-developer-api-guide): Copy-paste curl, JavaScript, Python, streaming, OpenAPI, and MCP examples for Quan 3.4 and Quan 3.4 Deep Research. - [Quan API Enterprise Developer Guide](https://stockup.cc/quan-api-enterprise-developer-guide): Admin and developer guide for Enterprise model aliases, Enterprise API keys, per-user token quotas, overages, organization token pools, and secure company deployment. - [OpenAPI YAML](https://stockup.cc/openapi.yaml): Machine-readable API schema. - [OpenAPI JSON](https://stockup.cc/openapi.json): Machine-readable API schema for tools that prefer JSON. - [Full AI Context](https://stockup.cc/llms-full.txt): Expanded crawler context for StockUp Quan, API usage, MCP setup, Enterprise aliases, and discovery pages.
