How this service works
Low-cost pay-per-call utility APIs for autonomous agents using x402 on Base.
Output
Returns a JSON object containing the transformed records with all specified field renames applied, unwanted keys filtered out (if a key list was provided), and default values filled in for any missing fields.
Example use cases
Normalizing API response field names
“I'm getting records from a legacy API where 'cust_nm' should be 'customer_name' and 'acct_no' should be 'account_number' — can you rename those fields across all 150 records so they match our internal schema?”
ETL pipeline key standardization
“Before loading these 400 product records into our database, rename 'prod_id' to 'product_id', 'cat' to 'category', and 'qty_avail' to 'quantity_available' across the whole batch.”
Aligning third-party data to internal format
“I have a set of contact records from a vendor where 'fn' means first name and 'ln' means last name — please rename those fields to 'first_name' and 'last_name' in all 80 records and fill in any missing 'email' fields with an empty string as the default.”
Technical details
Endpoint
POSThttps://one-search.one-engine.workers.dev/v3/records/rename/t2?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a lightweight, pay-per-call solution to bulk-rename fields across up to 500 JSON records without standing up your own transformation infrastructure. It is ideal for AI agents doing on-the-fly ETL normalization, schema alignment between APIs, or data pipeline preprocessing steps where field naming consistency matters and cost per call must stay minimal.
Side effects
- Exceeding the 500-record limit causes rejection or partial processing
- Invalid or non-object entries in the records array may cause errors
- Rename mapping referencing non-existent fields is silently ignored (no-op)
- Malformed JSON in request body returns a 4xx error
- Payment failure via x402 returns 402 Payment Required
