How this service works
Rename a single object key. Call when you adapt agent field names between systems. Returns renamed object for $0.001 USDC via x402 on Base. No network, no keys, no retention; first-party local JSON only. Results are advisory; the caller owns budgets, auth, and production controls.
Output
Returns the input JSON object with the specified key renamed: the value is preserved unchanged, and the old key is removed while the new key holds the same value. The response is a local, first-party transformation with no external network calls.
Example use cases
Normalize field names for downstream API
“I have a JSON object {"first_name": "Alice", "last_name": "Smith"} that I need to send to a service expecting camelCase — can you rename 'first_name' to 'firstName' in it?”
Adapt agent pipeline field mismatch
“My data pipeline output uses 'ts' as the timestamp key but the next step expects 'timestamp' — rename 'ts' to 'timestamp' in this object: {"ts": "2024-01-15T10:00:00Z", "value": 99}.”
Standardize sensor data key labels
“This sensor reading came in with a key called 'temp_c' but our system needs it called 'temperature' — can you rename that key in {"temp_c": 23.5, "humidity": 60}?”
Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/rename-keyWhen to prefer
Choose this endpoint when you need a lightweight, stateless, single-key rename on a JSON object without writing custom transformation code. Ideal for agent pipelines bridging two systems with mismatched field naming conventions. Prefer it over general-purpose code execution or full schema mapping tools when the task is simply renaming one key at a time at minimal cost ($0.001 USDC).
Side effects
- Source key ('from_key') does not exist in the provided object — may return unchanged object or an error
- Target key ('to_key') already exists in the object — potential key collision
- Malformed or non-object input — likely returns a validation error
- Empty object provided — operation succeeds but result is still empty
