# LUSID Developer Documentation Developer documentation for LUSID and related FINBOURNE services. ## Page conventions Every API documentation page is published in three forms at the same slug: - `` — the rendered HTML page (for humans) - `.json` — the OpenAPI fragment for that endpoint or schema - `.txt` — a short machine-readable summary with related links For LLM consumers, prefer fetching the `.txt` for orientation and lateral navigation, and fetch the `.json` only when you need full schema or parameter detail. Each service exposes a hierarchy of `llms.txt` indexes: `/api//llms.txt` lists the tag groups and links to per-tag indexes at `/api//endpoints//llms.txt`, and to a schemas index at `/api//schemas/llms.txt`. Drill down through these to find an operation or schema by name; each entry links to its `.txt` summary. Within an operation or schema JSON fragment, schema references look like `/api//schemas.json#/components/schemas/`. To fetch the referenced schema as a standalone file, transform that URL to `/api//schemas/.json` and fetch the sibling. The whole-service bundle at `/api//schemas.json` is also available if you want to resolve many refs at once. ## API services - **Access** — Access enables precise control over data and operations by managing permissions through a comprehensive role-based access control (RBAC) system.
