CSV Null Normalize
x402
CSV Null Normalize is a paid API for AI agents from api.delx.ai, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-15).
Normalizes caller-specified null tokens (e.g. 'NA', 'NULL', 'N/A') to empty cells in a CSV text, returning counts and a versioned deterministic result.

How this service works
CSV Null Normalize: CSV Null Normalize normalizes caller-selected CSV null tokens to empty cells from bounded caller-supplied values without an external provider. Call CSV Null Normalize before an agent hands structured data or a batch plan to a downstream tool with a stricter contract. Returns the bounded transformation or validation finding with counts, normalized values, and a versioned result contract for CSV Null Normalize as versioned deterministic JSON. Price: $0.001 USDC via x402 on Bas…
Output
Returns a versioned deterministic JSON object containing the normalized CSV text (with all specified null tokens replaced by empty cells), per-token replacement counts, total replacement count, and a versioned result contract identifier.
Example use cases
ETL pipeline null standardization
“Before I load this CSV export into our database, can you replace all occurrences of 'NULL', 'NA', and '-' with empty cells? Here's the CSV: name,age,city
Alice,NULL,NYC
Bob,NA,-”
Agent handoff data cleanup
“I'm about to pass this CSV to a downstream analytics tool that only accepts truly empty cells for missing values — can you normalize the null tokens 'N/A', 'NONE', and 'missing' to blank cells first? CSV: id,score,label
1,N/A,pass
2,NONE,fail
3,missing,pass”
Data quality preflight check
“Can you run a null normalization pass on this CSV and tell me how many cells were replaced? The null tokens are 'NaN', '#NULL!', and 'undefined'. CSV: product,price,stock
Widget,NaN,10
Gadget,#NULL!,undefined”
Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/csv-null-normalizeWhen to prefer
Choose this endpoint when you need a lightweight, deterministic, no-external-dependency service to standardize heterogeneous null representations in CSV text before handing data to a stricter downstream tool or pipeline. Prefer it over general-purpose LLM-based data cleaning when you need reproducible, auditable, versioned results with exact replacement counts.
Side effects
- CSV text exceeds 8192 character limit — request rejected
- null_tokens array exceeds 256 items — request rejected
- Malformed or non-CSV input text — may produce unexpected normalization output
- Empty null_tokens array — CSV returned unchanged with zero replacements
- Payment failure via x402 — request not processed
