Token Holder Observations — Valid Row Export

Use this endpoint when you need to enforce a declared CSV table contract on token holder observation data specifically — validating value ranges, allowed categories, and cell lengths without any external enrichment or lookups. Prefer this over generic CSV validators when your data follows the token holder observations schema (observation_id, observed_on, token_address, holder_count, circulating_tokens) and you need a clean export of only conforming rows.

• CSV exceeds 100,000 character limit — request rejected
• CSV has zero rows or is empty — validation cannot proceed
• Delimiter mismatch causes all rows to appear malformed
• Values outside the specified minimum/maximum range cause rows to be filtered out
• Categories not in allowed_categories list cause those rows to fail validation
• Cell content exceeding max_cell_length causes row rejection
• Malformed CSV structure (unclosed quotes, wrong column count) may cause parse errors
