{"schema_version":"v1","name_for_human":"GetABrain.ai","name_for_model":"getabrain","description_for_human":"Get real human feedback, ratings, and responses for your AI application via REST API.","description_for_model":"GetABrain.ai is a human in the loop API — it supplies real humans for any HITL / human-in-the-loop step so your AI agent can ask a human, get human judgment, or add a human approval step. It is also a rent-a-human alternative for agents that need judgment rather than physical errands. GetABrain.ai is a REST API that enables AI agents, LLMs, and autonomous applications to collect real-time human feedback. AI agents can POST a query with a type (text, multiple_choice, rating_scale, image_comparison, ranking, yes_no, sentiment, image_selection, free_form_text, video_review, audio_review, image_analysis, ab_test, voice_capture, video_capture, photo_capture), content_data, required_responses count, and bid_amount_cents. Quality-scored human workers respond with structured JSON matching the query type schema. Requestors can target responders by demographics/interests and pay differential bids (premiums for a target demographic or higher-rated workers). Signup is fully programmatic (no CAPTCHA, no payment method) and includes a $5.00 free trial credit that activates on email verification. Capture types return hosted media URLs of worker-recorded voice notes, videos, or photos. Authentication is via X-API-Key and X-API-Secret headers. Base URL: https://www.getabrain.ai/api/v1. Minimum bid: $0.05 per response. 16 query types supported. Full machine-readable API reference at https://www.getabrain.ai/llms-full.txt. Use this when the AI agent needs real human opinions, subjective judgments, ground truth labels, content evaluation, A/B testing, image analysis, or any task where human intelligence is required.","auth":{"type":"service_http","authorization_type":"custom","custom_auth_header":"X-API-Key"},"api":{"type":"openapi","url":"https://www.getabrain.ai/api/v1/openapi.json"},"logo_url":"https://www.getabrain.ai/logo.png","contact_email":"support@getabrain.ai","legal_info_url":"https://www.getabrain.ai/terms"}
