# Fuzzy Deduplication for JSON Arrays

> Fuzzy Deduplication for JSON Arrays is a paid API for AI agents from api.strale.io, paid per call via x402, $0.0216/call, status unknown (last checked 2026-09-14).

Removes duplicate objects from a JSON array using fuzzy string matching (Levenshtein + token sort) with configurable match fields and threshold

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

```sh
zero fetch --capability api-strale-io-90d357dc
```

Example prompt: I have this array of company objects and some of them are near-duplicates with slightly different spellings — can you deduplicate them using fuzzy matching on the 'name' and 'address' fields with a similarity threshold of 0.85?

## When to prefer this

Use this endpoint when you need to clean a JSON array of objects that may contain near-duplicate entries differing by typos, abbreviations, or minor formatting differences — especially when exact-match deduplication is insufficient. Ideal for customer lists, product catalogs, or any structured dataset where human-entered data introduces slight variations.

## Known failure modes

- Missing required 'data' query parameter returns error
- Threshold outside 0-1 range may produce unexpected results
- Non-array input for 'data' field causes validation error
- Non-existent match_fields silently skipped or cause error
- Very large arrays may hit timeout or size limits

## How this service works

Deduplicate a JSON array of objects using fuzzy string matching (Levenshtein + token sort). Specify match fields and threshold.

## Output

Returns a deduplicated JSON array with near-duplicate objects removed based on fuzzy similarity scoring across the specified match fields and threshold
