Breadth normally arrives as a subscription you use a tenth of. Here each call carries its own price, the free tier is genuinely keyless for the data feeds, and the account tools live inside the client so topping up is not a context switch. The thing to weigh is the corollary of routing across fifteen models: which one answers a given call is the platform's decision, not yours, so this suits work where the result matters more than the provenance of the model that produced it.
A metered marketplace of tools exposed as one MCP server. It routes work across models from several providers rather than binding you to one, and prices per call by tier — with a set of data tools that stay free and need no key at all.
- A large catalogue — the README states 250 tools — reachable from one connection, hosted or installed locally
- Language work across the obvious verbs: research, write, summarize, translate, code, analyze, sentiment, classify, extract, compare, explain, plan, decide, debate, proofread, rewrite, headline, keywords, questions, outline
- Beyond text: image analysis, document question-answering over your own material, diagram generation, and multi-step chains and batch operations
- Scraping surfaces for Google Maps, Twitter/X, Instagram, TikTok, YouTube and arbitrary websites
- Free data feeds needing no key — weather, crypto prices, exchange rates, holidays, time, jokes, quotes
- Utility APIs covering geocoding, WHOIS, SSL certificates, security headers, tech-stack detection, PDF extraction, stock history, forex, unit conversion and JSON, CSV and XML transforms
- Agent infrastructure: persistent memory, agent-to-agent messaging, task boards and a knowledge base
- Account management from inside the client rather than a billing portal — issue a key, top up, check what you have spent — `generate_api_key`, `buy_credits`, `check_usage`
- Model routing across providers by task, so the tool name is stable while what runs behind it is chosen for you
Nothing to start on the free data tools. For everything else, generate a key from inside the client — it comes with a small credit balance — and set it as `AIPAYGEN_API_KEY`. Credits top up by card, or you can pay per call in USDC on Base, Solana or Stellar with no signup. Pricing is tiered per call, from free data through standard, AI, scraping, premium and enterprise bands, with deep research the most expensive. Install `aipaygen-mcp` with pip and register the command, or connect to the hosted streamable-HTTP endpoint with no install. The server publishes as version 1.9.4 in server.json.
One command — aipaygen-mcp
