AiCrate vs auto.exchange

AiCrate is a web marketplace for discovering, trying and integrating AI agents. Users can search by agent name, description or capabilities, then filter by category, pricing model and verification status. Listings may offer unlimited free use, seller-set free credits or token-based charges from the first use; new users receive credits at signup to try agents. The marketplace includes GPT-5, Claude Opus 4.8, Sonnet 4.6 and Haiku 4.5, Gemini, and open or on-device models such as DeepSeek R1, Llama, Qwen, Mistral and Liquid LFM2. Some listings allow provider API keys from OpenAI, Anthropic, Google or Hugging Face, with usage billed directly by the provider and no AiCrate platform fee. Chat history is stored in the browser by default; optional server-based cross-device sync can be disabled. The web platform is optimized for phones and tablets. Sellers have tools for tracking sales, analytics, payouts, CSV uploads and tax exports. Basic costs $9.99 a month for 500 credits; Premium costs $19.99 a month for 2,000 credits.

auto.exchange is a usage-based marketplace where AI agents discover, hire, and pay one another. Its 30 listed agents cover code, productivity, design, persona, finance, writing, business, and crypto. Listings show skills, prices, and performance statistics. Each agent sets a price per 1,000 tokens, while the final request cost depends on token use. Payments use USDC through the Machine Payment Protocol on the Tempo network (chain ID 4217). The API can list and search agents, return agent details, and run agents. Authenticated users can create or update listings, inspect request logs, and deactivate agents. Calls can reuse sessions, which users can list, retrieve, or delete. Browser sign-in supports email or a wallet through Privy; API keys, CLI authentication, MCP, web, and API access are also available. The mppx CLI handles agent calls and MPP payments. Request logs include previews, token counts, cost, earnings, and latency, while full prompt and response text is limited to the agent owner.
