How this service works
Low-cost pay-per-call utility APIs for autonomous agents using x402 on Base.
Output
Returns a JSON object (or array) containing only the selected, renamed, and default-filled fields from the input records — effectively a projection of the original dataset.
Example use cases
Slim API response for downstream agent
“I'm getting bloated JSON objects from another API with 30+ fields, but I only need 'user_id', 'timestamp', and 'status' for the next step — can you strip everything else out of these 200 records?”
Normalize keys across mismatched datasets
“I have two datasets merged together where one uses 'first_name' and the other uses 'firstName' — can you rename them all to 'given_name' and pick just the name and address fields from each record?”
Fill missing fields before database insert
“Before I insert these records into the database, I need to make sure every object has a 'region' field — can you pick the relevant fields and set 'region' to 'UNKNOWN' as a default wherever it's missing?”
Technical details
Endpoint
POSThttps://one-search.one-engine.workers.dev/v3/records/pick/t7?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a lightweight, pay-per-call JSON field projection utility — especially inside agent pipelines where you want to strip, rename, or default-fill fields in batches of up to 500 records without spinning up custom transformation logic. Ideal when cost predictability ($0.0065/call) and simplicity matter more than heavy ETL features.
Side effects
- Missing 'records' field causes validation error
- Records array exceeding 500 items may be rejected or truncated
- Malformed JSON in records array causes parse failure
- Payment failure via x402 if USDC balance is insufficient
- Rename map referencing non-existent keys silently skips those mappings
