Example prompt: Can you normalise the string fields in my library circulation records? I have 4 rows — branch 'group-a' on 2026-10-01 with 10 checkouts and 1 renewal, 'group-b' on 2026-10-02 with 20 checkouts and 2 renewals, 'group-a' on 2026-10-03 with 15 checkouts and 3 renewals, and 'group-b' on 2026-10-04 with 30 checkouts and 4 renewals.

## When to prefer this

Choose this endpoint when you need to normalise and standardise string fields (branch names, dates) in library circulation data locally, without sending data to external enrichment services. Ideal for small-to-medium batches (up to 200 rows) where data quality and consistency are needed before downstream analytics or reporting.

## Known failure modes

- Fewer than 1 row submitted — validation error
- More than 200 rows submitted — request rejected
- Row missing required fields (row_id, branch, date, checkouts, renewals) — validation error
- Date field not matching YYYY-MM-DD pattern — validation error
- branch or row_id string exceeding 80 characters — validation error
- Payment of 0.01 USDC not completed — request blocked
