Show HN: IngressKit – API Plugin for Cleaning CSVs, Webhooks, and AI JSON Output

I’ve lost count of how many times I’ve rewritten CSV importers and webhook parsers over the years.

I built IngressKit to handle that once and for all. It’s an API plugin that:

Cleans & maps CSV/Excel uploads to your schema.

Harmonizes webhook payloads (Stripe, GitHub, Slack, etc.) into one predictable format.

Normalizes JSON output from LLMs or third-party APIs to a strict schema.

Key details:

Deterministic — not probabilistic — normalization.

Per-tenant memory so it gets better over time.

Audit trail for every change.

Quick example:

curl -X POST "https://api.ingresskit.com/v1/json/normalize?schema=contacts" \ -H "Content-Type: application/json" \ -d '{"Email":"USER@EXAMPLE.COM","Phone":"(555) 123-4567","Name":" Doe, Jane "}'

→ Returns perfectly normalized JSON with consistent keys, formatting, and validation.

Would love feedback from the HN community — particularly on:

Other messy data sources you’d want to normalize.

Whether you’d prefer more SDK examples or hosted API endpoints.
