Free AI APIs, no credit card
This page lists only offers where the provider's own page says no credit card or payment method is required. Many popular free tiers (Gemini, Groq, Cloudflare Workers AI) may not need a card either, but we haven't confirmed that on their pages, so they're on the main list with "unknown".
For LLM inference specifically, see the free tiers on the main table. Everything below is supporting infrastructure for AI apps: speech-to-text, web search for agents, scraping, vector and Postgres databases, observability and code sandboxes.
