Alchemyst AI is a hosted context service for storing business knowledge and retrieving relevant information across AI agents. Its product REST API covers document ingestion, semantic context search, conversation memory, traces and organization-scoped context. Official TypeScript/JavaScript and Python SDKs are available; an API key is required for product operations. The public pricing page lists Free at $0 with 50,000 requests per month, 500 MB of context storage and one workspace, and Pro at $49/month with 1,000,000 requests, 50 GB and five workspaces. Enterprise pricing is custom. The usage calculator also displays operation charges with inconsistent unit labels; confirm effective usage charges and allowances before production use. See https://getalchemystai.com/pricing and https://getalchemystai.com/docs. Verification on October 31, 2026: the product Swagger specification is OpenAPI 3.1 with 23 paths, and an unauthenticated context-list request correctly returned 401. The legacy SSE MCP endpoint at https://mcp.getalchemystai.com/mcp/sse initialized and listed four tools. The documented Streamable HTTP /mcp endpoint and OAuth discovery returned 404, so current product MCP authentication and context operations remain unverified. The separate public website MCP at https://getalchemystai.com/mcp initialized, listed three documentation-discovery tools and returned documentation links from a real call; it is not the product context store. No private context, writes, authenticated retrieval or paid operations were tested.

Integration checklist
- Access: Confirm the api key authentication flow, credential scope, rotation process, and whether calls can be attributed to a user or service identity.
- Client support: Official or documented clients are listed for typescript, python.
- Automation: OpenAPI: listed as available; MCP: listed as available; CLI: not currently recorded. Confirm each requirement in the provider's current documentation.
- Operations: Test rate limits, timeouts, retry safety, error payloads, logs, data retention, and the current free-tier and paid pricing model with production-like volume.
