The developer platform for B2B transactions

Q: Is Stanza a healthcare clearinghouse?

No. Stanza is a parser and validator API. We convert complex B2B files (like ANSI X12 and ISO 20022) into clean JSON in 3 milliseconds so you can catch errors before sending files to your clearinghouse or bank. We do not route files to insurance payers, so you avoid per-claim fees and vendor lock-in.

Q: How does Stanza achieve zero data retention?

Stanza processes requests purely in ephemeral memory. Payloads stream into an in-memory worker, undergo instantaneous parsing and SNIP validation, and return as JSON before the worker terminates. No database writes, cache lookups, or persistent disk logs retain payloads.

Q: Can we run Stanza on AWS Lambda in our private VPC?

Yes. While Stanza is deployed globally across multi-region serverless edge nodes for sub-5ms public latency, enterprise customers can deploy the same deterministic platform within private AWS Lambda VPC environments. BAA execution is on the compliance roadmap and not yet available.

Q: How does the MCP Server work with AI agents?

Stanza provides a Model Context Protocol (MCP) server that exposes tool definitions directly to LLM agents (Claude Desktop, OpenAI Assistants, LangChain). Instead of prompting an LLM to hallucinate fragile EDI loops, the agent invokes Stanza's deterministic parser tool to receive verified, structured JSON schema outputs.

AI-ready. Sub-2ms edge compute. Zero data retention. Validate, parse, and transform regulated B2B payloads at the edge.
