Dedupe API

Detect records that represent the same entity within a single dataset, with a transparent similarity basis.

What it does

Find duplicate records within a dataset.

When to use it

Reach for Dedupe when you need to answer: “Which records are duplicates?” It sits in the Prepare stage of the catalog — clean and de-duplicate raw data.

Endpoint & cost

POST /api/v1/dedupe

Cost: 1 Zap. Zaps draw down your shared monthly allowance; requests that fail validation are not charged.

Authentication

Send your key as a bearer token: Authorization: Bearer zap_live_…. See Authentication for key management and the alternate header.

Example request

curl https://api.zapiit.com/v1/dedupe \
  -H "Authorization: Bearer zap_live_••••••" \
  -H "Content-Type: application/json" \
  -d '{"records":[{"id":1,"email":"a@acme.com"},{"id":2,"email":"A@ACME.com"}]}'

Every response is structured JSON and includes a request_id. Full field-level request and response schemas for this endpoint live in the OpenAPI spec and the API reference.

Errors & limits

Errors use one consistent shape ( error.code, error.message, request_id). See Errors and Rate limits.

SDK

The TypeScript SDK (@zapiit/sdk) is coming soon. Until it ships, call the endpoint over HTTPS with the example above — the API is plain JSON and needs no dependency.

Try it

Select Dedupe in the playground to see the request, or run it live with your API key.
