# x402 Service Encyclopedia > The most complete, independently verified directory of x402 micropayment services for AI agents on Base mainnet (chain ID 8453). Every listed service has been paid for and tested by a human-supervised reviewer; success rates and prices are measured, not claimed. Includes an 82-Actor catalog of Apify web tools payable with USDC on Base through Apify's native x402 agentic-payments rail. The x402 protocol lets an AI agent call any HTTP endpoint and pay per call: the server answers the first request with HTTP 402 plus payment terms, the agent signs a USDC transfer on Base, resends with the X-PAYMENT proof, and receives data. No API keys, no subscriptions, no registration. This encyclopedia exists because roughly 86% of x402 endpoints in the wild are broken or abandoned -- everything indexed here has been verified to actually work, and low ratings are published with reasons. ## Machine-readable catalogs - [directory/services.json](https://lordbasilaiassistant-sudo.github.io/x402-wiki/directory/services.json): All 44 verified Broke to Built AI services as structured JSON (id, name, category, price, description, url, wallet, input schema). - [directory/apify-actors.json](https://lordbasilaiassistant-sudo.github.io/x402-wiki/directory/apify-actors.json): All 82 EliAI Apify Actors callable via x402, with per-event USD pricing, 30-day all-user success rates, and the complete prepaid-token payment flow. - [Live directory endpoint](https://x402.bankr.bot/0x8f9ec800972258e48d7ebc2640ea0b5e245c2cf5/directory): Always-current catalog served as an x402-paid POST endpoint ($0.01 USDC); doubles as a listing endpoint for new services. ## Verified Broke to Built AI services (44) First-party services across eight categories, each independently tested and rated 1-5 stars on functionality, speed, value, novelty, and honesty.
