How this service works
Exact native USDC on Base; externally owned wallets only. Generate a private 32-byte random request_token for each new job, persist the entire body, and reuse it for challenge/retry and recovery. The token grants result access. Do not log or share it. HTTP 202 or an uncertain transport failure requires recovery with the identical body without a signature, never a new purchase. Results expire after 24 hours. Ten bounded deterministic services. Local execution is free; hosted jobs require customer-authorized payment only when billable.
Output
Returns a JSON object with a 'result' containing: duplicate groups (each with a count and the indices of matching records), a list of checked keys, matching configuration (trim and ignore_case settings), a summary string, a scope note explaining what 'duplicate' means in this context, a list of any missing key fields, the service version, and overall status. The top-level response also includes the payment state and service name.
Example use cases
Inventory deduplication before warehouse sync
“I have a list of 30 inventory entries and I want to find any duplicates based on the 'sku' and 'warehouse' fields before syncing to our WMS — can you group the ones that match on those keys?”
Customer list deduplication by email and name
“Here are 50 customer records from two different imports — find any duplicates where both 'email' and 'last_name' are the same, and ignore case differences.”
Order line deduplication before invoice generation
“Before I generate invoices, can you check these order line items for duplicates by 'order_id' and 'product_code'? I want to make sure no line got submitted twice.”
Technical details
Endpoint
POSThttps://taskmint-sign-proof-node22-production.up.railway.app/api/agent/record_duplicates?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need lightweight, deterministic duplicate detection across a small-to-medium set of structured records (up to 50) based on exact key field matching. It is ideal for pre-import validation, data quality checks, and deduplication pipelines where you want exact-match grouping (not fuzzy matching or merge operations) and need the result to be reproducible and idempotent via request_token retry semantics.
Side effects
- Missing required 'records' or 'keys' fields returns a validation error
- Records array exceeds 50 items or keys array exceeds 10 items may be rejected
- Key values that are absent in some records are reported in the 'missing' field
- Invalid request_token format (not 64-char lowercase hex) causes rejection
- HTTP 202 or transport uncertainty requires retry with the identical body and token, never a new request
- Results expire after 24 hours from job submission
- Payment failure or insufficient USDC balance prevents job execution
