Solution
Deterministic transaction enrichment
TxnKit helps teams solve deterministic enrichment with one safe descriptor, confidence-aware output, and warnings when identity evidence is weak.
Target intent
avoid unpredictable live research during transaction display rendering.
TxnKit returns warnings for misses instead of doing live research.
Raw descriptor
SPOTIFY USA 877-7781161API-shaped output
{
"input": {
"descriptor": "SPOTIFY USA 877-7781161",
"country": "CA"
},
"output": {
"merchant_name": "Spotify",
"category": "Streaming subscription",
"confidence": "medium",
"signals": [
"processor_pattern",
"merchant_alias",
"category_hint"
],
"warnings": [
"review_low_confidence_matches_before_showing_logo"
],
"logos": []
}
}Low-confidence results should keep fallback labels and warnings visible instead of forcing a guessed logo or website.
When to use
- You need deterministic enrichment for transaction-feed UI, audit, or import review workflows.
- You can send safe anonymized descriptors without customer PII or full statement text.
- You want API-shaped output that a developer can inspect before wiring product UI.
When not to use
- TxnKit returns warnings for misses instead of doing live research.
- Do not use TxnKit to process card numbers, account numbers, full statements, bank credentials, emails, phone numbers, addresses, customer names, or customer PII.
- Do not use TxnKit when the product requirement is guaranteed merchant identity, every-merchant resolution, or contracted uptime terms.
Proof surfaces
The public contract is POST /v1/enrich, backed by the OpenAPI file, benchmark examples, privacy rules, and deterministic request-path tests.
