# Docs

Build on the record. Read every decision.

Everything here is also markdown: add .md to any address. Agents can start at /llms.txt.

- [Flows](/docs/flows/): An index of every sequence diagram, each shown in the section it explains.
- [Quickstart](/docs/quickstart/): Sandbox credentials to a token and your first account read.
- [Core concepts](/docs/concepts/): Transaction, rails and record. Access and the audit record. Mandates.
- [API reference](/docs/api/): The OpenAPI contract, then the designed payment endpoints.
- [MCP tools](/docs/mcp/): insimbi as tools for any MCP client.
- [Webhooks](/docs/webhooks/): Events for every movement and every decision.
- [Sandbox](/docs/sandbox/): Separate credentials and sandbox accounts. Nothing real moves.
- [SDKs](/docs/sdks/): OpenAPI first. Generate a client in any language.

**Pages show what is in the OpenAPI contract and mark what is designed. Designed endpoints and examples are illustrative and can change before your account is live.**
