# 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).

## Apify Actors payable with x402 (82)

Every public Actor under the [eliai account](https://apify.com/eliai) is whitelisted for [Apify agentic payments](https://docs.apify.com/integrations/x402): pure pay-per-event pricing, event charges only, limited permissions, KYC-verified developer. An agent buys a prepaid token from the Apify AGI gateway with one x402 payment (minimum $1 in USDC on Base), then runs any Actor with that Bearer token -- no Apify account needed.

## Community submissions awaiting verification

Providers submitted via issue, health-checked but not yet first-party paid-tested. Not in services.json until we personally verify. A health check confirms a live HTTP 402 whose `payTo` matches the submitted wallet -- it says nothing about the data behind the paywall.
