How this service works
Low-cost pay-per-call utility APIs for autonomous agents using x402 on Base.
Output
An object containing up to 10 transformed JSON records with fields renamed according to the provided mapping, with any specified default values applied and optional key filtering.
Example use cases
Normalize API response field names
“I'm getting records from a third-party API with weird field names like 'usr_nm' and 'usr_em' — rename them to 'username' and 'email' across these 200 records and show me the top 10.”
Migrate legacy database export schema
“I have a CSV export turned into JSON where all the columns use old snake_case names like 'first_name' and 'last_name' — remap them to 'firstName' and 'lastName' for our new system, top 10 results please.”
Standardize event log keys for analytics
“These event log entries have inconsistent key names like 'ts', 'evt_type', and 'usr_id' — can you rename them to 'timestamp', 'eventType', and 'userId' across my batch of records?”

Choose this endpoint when you need a lightweight, pay-per-call solution to batch-rename fields across JSON records (up to 500 at a time) and only need the top 10 results. It is ideal for agents that need ad-hoc schema normalization without standing up a dedicated ETL pipeline, and is cost-effective at $0.03 USDC per call via x402 on Base.
Side effects
- Missing required 'records' field returns a validation error
- Records array exceeding 500 items may be rejected or truncated
- Invalid rename mapping (non-object) causes a schema error
- Payment failure via x402 returns HTTP 402 before processing
- Malformed JSON in records causes a parse error
