Open Source

Built on Metriqual. Receipts included.

Live apps, MIT licensed, each proving one production problem the proxy solves. Every app ships with a step-by-step guide to run it yourself and the integration-cost receipts — lines of code, dollars per thousand requests. Fork anything as a starting point.

TruthLens

Same question. Same model. One lane fact-checks itself.

A research assistant that answers every question twice: once raw, once through a proxy key with the hallucination blocker attached. Fabricated citations, fake statistics, and overconfident claims get caught by ReAct + Chain-of-Verification running inside the proxy — the app contains zero verification code.

Proves: Hallucination Blocker

Failover Bot

Kill a provider mid-conversation. The user never notices.

A support chatbot wired to a failover chain — when the primary provider errors or times out, the next one takes over automatically on the same key.

Proves: Automatic Failover
Coming soon

Omni Studio

Script → images → voiceover → video. One key.

A content studio that chains text, image, TTS, and video generation across providers — through a single Metriqual key with one SDK.

Proves: Every Modality, One Integration
Coming soon

Capped Keys

Give every client an AI budget that cannot be exceeded.

A client-billing starter where each end-customer gets their own proxy key with a hard spend cap and per-key usage analytics for invoicing.

Proves: Per-Key Spend Controls
