LLM inference API for AI agents: OpenAI-compatible chat completions paid per request in USDC on Base. No account or API key. Summarize, classify, extract, translate, generate and chat with gpt-5.4-nano, gpt-5.4-mini, gpt-5.4, gpt-5.5, gpt-4o-mini and more. Misses billed at cost + 4% on actual token usage (upto scheme); deterministic repeats (temperature 0) are cache hits billed at 55% of provider price — loops get cheaper automatically. From $0.001/call, standard OpenAI POST format.

Text embeddings API for AI agents: OpenAI-compatible /v1/embeddings paid per request in USDC on Base — no account or API key. Embed documents for RAG, semantic search, clustering, deduplication with text-embedding-3-small or text-embedding-3-large. Embeddings are deterministic, so repeated texts hit our cache and bill at 55% of provider price — re-embedding a corpus costs roughly half. Misses at cost + 4%, from $0.001/call. Standard OpenAI POST format.
