Background

Roadmap reference: ROADMAP.md > P3 > API pagination

The /analyze/batch and /jobs endpoints return all records in a single response. As the dataset grows this will cause slow responses, high memory usage, and poor user experience.

What to do

  1. Add cursor-based pagination to both endpoints:
    • Accept query parameters cursor (opaque string encoding the last seen ID/timestamp) and limit (default 20, max 100).
    • Return a next_cursor field in the response when more results are available (null when on the last page).
  2. Update the frontend job list to use infinite scroll or a "Load more" button that passes the cursor.
  3. Document the pagination contract in the FastAPI docstring / OpenAPI description.
  4. Add tests asserting correct cursor behaviour (first page, subsequent page, last page).

Acceptance criteria

  • GET /jobs?limit=10 returns at most 10 results and a next_cursor.
  • GET /jobs?cursor=<next_cursor> returns the next page.
  • GET /jobs?cursor=<last_cursor> returns an empty list and next_cursor: null.
## Background Roadmap reference: ROADMAP.md > P3 > API pagination The `/analyze/batch` and `/jobs` endpoints return all records in a single response. As the dataset grows this will cause slow responses, high memory usage, and poor user experience. ## What to do 1. Add cursor-based pagination to both endpoints: - Accept query parameters `cursor` (opaque string encoding the last seen ID/timestamp) and `limit` (default 20, max 100). - Return a `next_cursor` field in the response when more results are available (null when on the last page). 2. Update the frontend job list to use infinite scroll or a "Load more" button that passes the cursor. 3. Document the pagination contract in the FastAPI docstring / OpenAPI description. 4. Add tests asserting correct cursor behaviour (first page, subsequent page, last page). ## Acceptance criteria - `GET /jobs?limit=10` returns at most 10 results and a `next_cursor`. - `GET /jobs?cursor=<next_cursor>` returns the next page. - `GET /jobs?cursor=<last_cursor>` returns an empty list and `next_cursor: null`.

Closing: already implemented in main. /jobs endpoint uses cursor-based pagination with next_cursor field. database.py has list_jobs() with cursor support.
