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 containing the normalized CSV string under result.csv, a status field ('pass'), operation metadata ('data_batch:csv_null_normalize'), and an evidence block with a SHA-256 hash of the input, confirmation that no data was retained, and the count of external calls made (always 0).
Example use cases
Pipeline ingestion null cleanup
“I have a CSV export from our database with inconsistent null representations — some cells say 'NULL', others say 'N/A', and some say '-'. Can you normalize all of those to empty fields so I can load it cleanly into our pipeline? Here's the CSV: 'id,name,score\n1,Alice,NULL\n2,Bob,N/A\n3,Carol,-'”
Data quality preprocessing for ML
“Before I feed this training CSV into my model, I need to standardize all the missing value tokens. Replace 'missing', 'unknown', and 'n/a' with proper empty fields in this data: 'feature1,feature2,label\nmissing,0.5,1\n0.3,unknown,0\n0.7,n/a,1'”
ETL transform for reporting
“Our sales report CSV has a mix of 'NONE' and 'null' and empty strings standing in for missing values — can you normalize all of them to truly empty CSV fields using 'NONE' and 'null' as the null tokens? CSV: 'region,sales,quota\nWest,NONE,5000\nEast,null,3200\nNorth,2100,null'”
Technical details
Endpoint
POSThttps://commerce.delx.ai/api/v1/x402/csv-null-normalize?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a verifiable, pay-per-call, no-signup CSV null normalization with cryptographic evidence of non-retention. Ideal for agents handling sensitive or regulated tabular data where auditability matters, or for lightweight ETL steps in agent workflows that must avoid persistent data storage. Prefer over self-hosted solutions when you need provable processing guarantees without infrastructure overhead.
Side effects
- Input text exceeds 8192 character limit — request rejected
- null_tokens array exceeds 256 items — request rejected
- Malformed JSON body — 400 error
- Payment not included or invalid USDC payment via x402 — 402 payment required
- Network timeout on large CSV payloads
