Neon Function proxy that routes AI Gateway decisions with TypeSafe Jev.

Classification & Routing37%Runner-up: Verification & Guardrails

What it is

A public showcase of TypeSafe Jev judgments: a Neon Function proxy in front of the Neon AI Gateway. It inspects request bodies and optionally forwards the same bytes to a caller-chosen HTTPS URL. Aimed at developers and agents.

How it uses Jev

Jev inspects the request body and returns a judgment (pass, review, or block). The judgment is exposed via the x-neon-action response header and timing via x-neon-jev-ms. On pass with a target, the same bytes are forwarded upstream; review and block never forward.

Technique worth stealing

Inspect the body, then optionally forward the same bytes to a caller-chosen HTTPS URL.

Try it

bun install; neon link -y; neon env pull; neon deploy --env .env.local; bun run test
