Find the right paid API for a task across the whole x402 market, not only agents
Find the right paid API for a task across the whole x402 market, not only agentsvc.io: describe what your agent needs in plain words ("convert a web page to markdown", "token price on Solana", "transcribe audio") and get the best matching x402 endpoints from about 45,000 listed ones, each with provider, URL, method, price in USD, payment networks, an input hint, and whether it answered our own check with a valid 402 (reachable, checked_at, response time).

Paid test badge: not yet. The checks above are free: we call the tool without paying and read the payment request it sends back. The Verified badge needs paid calls whose answers match the promised output, and nobody can buy a badge.
