x402
CSV Rename Columns 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).
Renames CSV header columns according to a caller-supplied mapping, returning the transformed CSV with counts and normalized values as deterministic JSON.

How this service works
CSV Rename Columns: CSV Rename Columns renames CSV header columns using a caller mapping from bounded caller-supplied values without an external provider. Call CSV Rename Columns 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 Rename Columns as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base. First…
Output
Returns a versioned deterministic JSON object containing the transformed CSV with renamed headers, counts of columns renamed, normalized values, and a versioned result contract confirming the transformation outcome.
Example use cases
Normalizing export before CRM import
“I've got a CSV export from our old system with headers like 'cust_id', 'cust_nm', and 'rev' — rename them to 'customer_id', 'customer_name', and 'revenue' so it matches what the CRM expects.”
Standardizing analytics pipeline input
“Our data pipeline needs columns named 'event_date', 'user_id', and 'session_duration', but the raw CSV has 'date', 'uid', and 'dur' — can you rename those headers for me?”
Preparing CSV for downstream agent tool
“Before I send this CSV to the reporting agent, I need to rename 'qty' to 'quantity' and 'prc' to 'price' — the downstream tool won't accept anything else.”
Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/csv-rename-columnsWhen to prefer
Use this endpoint when an agent needs to programmatically rename CSV column headers to match a downstream tool's strict schema contract, without needing an external provider or storing data. Prefer this over general-purpose code execution when you want a deterministic, versioned result with counts and normalized output rather than raw script output. Ideal as a lightweight pre-processing step in a data pipeline or multi-agent workflow.
Side effects
- Mapping references a column name not found in the CSV headers — transformation may be partial or return a validation error
- CSV text exceeds 8192 character limit — request rejected
- Mapping object exceeds 128 properties — request rejected
- Malformed CSV input (e.g. inconsistent delimiters) — may cause unexpected header parsing
- Empty mapping object — CSV returned unchanged with zero renames counted
