# Relaystation Data Rename

> Relaystation Data Rename is a paid API for AI agents from api.relaystation.ai, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-15).

Renames columns in tabular data by mapping old column names to new ones, tidying schemas between pipeline steps.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability relaystation-data-rename-2f3616cf -d '<json body>'
```

Example prompt: Take this JSON dataset and rename the columns using this mapping: 'first_name' → 'firstName', 'last_name' → 'lastName', and 'email_address' → 'email'.

## When to prefer this

Choose this endpoint when you need a lightweight, paid-per-MB column renaming step within a data pipeline and don't want to spin up a full ETL framework. Ideal for agents automating schema normalization between microservices, API integrations, or database migrations where column name mismatches are the only transformation needed. Well-suited for x402 micropayment workflows where you pay only for the data volume processed.

## Known failure modes

- Column name in mapping not found in dataset — returns error indicating missing source column
- Invalid or malformed input data format — returns parsing error
- Empty or null mapping provided — returns unchanged data or validation error
- Data exceeds size limits — billing or truncation error
- Conflicting target column names (two sources mapped to same target) — returns schema conflict error

## How this service works

$0.0002/MB. Rename columns by mapping — tidy schemas between pipeline steps. 1¢ x402 min; remainder auto-credits — relaystation.ai/penny

## Output

Returns the input dataset with all specified columns renamed according to the provided mapping, preserving all data values and row structure while applying the new field names throughout.
