# NanoTools — x402 pay-per-call API for AI agents **44 tools. No signup. No API keys. Pure [x402](https://www.x402.org/) micropayments on Base mainnet.** Agents pay per call with USDC ($0.001–$0.03) via the x402 protocol — the HTTP 402 flow is fully automatic with any x402-capable client/wallet. ## 🔗 Discovery endpoints | What | URL | |---|---| | Tool catalog for LLMs | https://nano.stacknodehost.com/llms.txt | | OpenAPI 3 spec (x402 prices in extensions) | https://nano.stacknodehost.com/openapi.json | | x402 discovery | https://nano.stacknodehost.com/.well-known/x402 | | A2A agent card | https://nano.stacknodehost.com/.well-known/agent.json | | Health | https://nano.stacknodehost.com/health | ## 🧰 Tool groups - **Trends & SERP** — Google Trends (timeline, related queries, regions), Google SERP, Yandex SERP, wordstat regions - **SEO** — meta audit, robots.txt audit, readability audit, IndexNow submit - **Chromium tools** — page screenshot, page PDF, OG-image generation (real headless Chromium) - **Data** — weather (open-meteo), FX rates (ECB), whois (RDAP), RSS parse - **Utilities** — QR, JWT, cron parse, hash, uuid, base64, url encode, slug, datetime, ... ($0.001 tier) ## 💳 Payment x402 `ExactEvmScheme` on **Base (eip155:8453)**, payTo `0x4F568Bf0cE8537CBE7a0DAF1A43C955e0a648db9`, facilitator `https://facilitator.openx402.ai`. Prices are declared per-tool in the discovery endpoints (`x-price-usd` extension in OpenAPI). ## 🚀 Quick start with any x402 client Point your agent at any tool URL from `llms.txt` — the first call returns `402` with payment requirements, the client signs USDC, retries with `X-PAYMENT` header and gets the result.
