How I Built Veltrix: An Autonomous Social Engine Orchestrating 18+ APIs on a $0.0002 Budget

Short summary

The author built Veltrix, an autonomous social media publishing engine that orchestrates 18+ APIs to generate, audit, and publish content to Instagram and Threads for ~$0.0002 per post. The architecture uses a gated cost model where free models (Groq, Cerebras) perform consensus auditing before paid models (Gemini Pro) generate final content. The article includes full architecture diagrams, workflow steps, and Python code for the adversarial auditing module.

• •Veltrix orchestrates 18+ APIs to autonomously publish social media content at ~$0.0002/post
• •Cost-gated architecture: free models audit drafts before paid Gemini Pro generates final output
• •Dual-model consensus (Groq + Cerebras) requires 2-of-2 approval before publishing
• •Includes Python code for text auditing, embedding deduplication, and Playwright-based slide rendering
