How this service works
Deterministic JSON object processing utility: Return last object entries; parameter=32. Tier 8/10 provides progressively richer diagnostics.
Output
A JSON response containing the last 32 entries (key-value pairs) of the submitted JSON object, along with Tier 8 progressive diagnostic information about the processing operation.
Example use cases
Trim large config object to recent entries
“I have a huge configuration JSON object and I only need the last 32 settings — can you strip it down to just those trailing entries for me?”
Extract tail of API response object
“This API response JSON object has hundreds of fields, but I only care about the last portion — pull out the final 32 entries so I can process them.”
Paginate through object properties
“I'm working through a JSON object in chunks and need the last 32 key-value pairs from it — can you extract just those for me with the Tier 8 diagnostics?”
Technical details
Endpoint
POSThttps://one-search.one-engine.workers.dev/v9/record-process/last-entries/p9/t8?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a deterministic, low-cost utility to extract the last N entries from a JSON object and want richer diagnostic output (Tier 8). It is ideal for agents that need to slice tail data from large JSON objects without writing custom parsing logic, and where pay-per-call micro-pricing via x402 on Base is acceptable.
Side effects
- Invalid or malformed JSON object in request body returns an error
- Empty JSON object may return empty result set
- Parameter mismatch or unsupported object structure may cause processing failure
- Payment not received or insufficient USDC balance causes 402 rejection
- Non-object JSON input (e.g. array or primitive) may not be supported
