LetsClarify — Human-in-the-Loop API for AI Agents The Problem: AI agents are becoming increasingly autonomous — but there are moments when they need a human. An approval, a decision, missing information. Until now, developers had to build custom frontends, host forms, and process data manually. That takes time and distracts from the actual agent workflow. The Solution: LetsClarify is an API that lets AI agents create a form in a single HTTP call. Each recipient gets a unique URL — shareable via email, Slack, WhatsApp, or embedded on any website. Once the human responds, the agent gets structured JSON back and can seamlessly continue its workflow. How It Works: 1. Your agent sends a JSON schema via POST to the API 2. LetsClarify generates a hosted form with unique URLs per recipient 3. The human fills out the form in their browser 4. Your agent receives the response as structured JSON — via webhook or polling Use Cases: - Approval Workflows — Get human sign-off on budgets, plans, or AI-generated proposals before execution - Data Collection — Gather structured information from people who don't have API access - Human Verification — Have humans review AI outputs before committing irreversible actions - Decision Points — Let humans choose between agent-generated options with full context - Consent & Agreement — Collect explicit consent before a workflow proceeds Features: - 7 field types (text, textarea, select, radio, checkbox, checkbox group, file) - Up to 10,000 recipients per form - File uploads (up to 10 files, 10 MB each) - Webhooks with retry and exponential backoff - Field validation (regex, min/max length, required) - Embed widget for any website (2 lines of code) - Auto-deletion after configurable retention period - GDPR compliant, hosted in Germany, no tracking, no cookies Why LetsClarify? - No SDK required — pure HTTP - No frontend to build — forms are hosted - No account dashboard — just an API key and go - Free, no credit card needed
