How this service works
Pay-per-result APIs for agents. No signup. Exact price. Verifiable delivery. USDC on Base + Solana via x402.
Output
Returns a JSON object indicating whether the CSV passed validation (passed: true/false), a list of any missing column names, the operation status ('pass' or 'fail'), and evidence metadata including whether input was retained (always false), the SHA-256 hash of the input for verifiability, and the number of external calls made (always 0).
Example use cases
Pre-import CSV schema validation
“Before I import this CSV into the database, check that it has all these required columns: 'product_id', 'name', 'price', 'stock_qty'. Tell me if anything is missing.”
User upload validation in data pipeline
“A user just uploaded a CSV — here's the text. Can you verify it contains 'first_name', 'last_name', 'email', and 'phone' columns before we proceed with processing?”
ETL pipeline column check
“I'm running an ETL job and need to confirm this CSV has 'order_id', 'customer_id', 'amount', 'currency', and 'timestamp' before I start transforming it. Can you check?”
Technical details
Endpoint
POSThttps://commerce.delx.ai/api/v1/x402/csv-required-columns-check?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a lightweight, pay-per-use, no-signup CSV header validation with cryptographic evidence of non-retention. Ideal for agent pipelines that process user-uploaded CSVs and need to gate downstream steps on schema compliance. Prefer over custom validation logic when auditability (SHA-256 evidence) and zero data retention are important requirements.
Side effects
- Malformed or non-CSV text input may produce unexpected column detection results
- Column name matching may be case-sensitive, causing false negatives if header casing differs
- CSV with no header row will likely report all required columns as missing
- Input text exceeding 8192 characters will be rejected
- Required columns array exceeding 256 items will be rejected
- Payment failure (x402) will prevent the call from completing
