BROWSE the catalog: keyword search over Agent402's 516 pay-per-call web tools, returning a LIST of candidates to compare (its counterpart find_tool resolves a task to ONE ready-to-run pick - search explores, find decides). Categories: live market data (stock-quote at $0.003), encoding, crypto, text, time, math, validation, unit conversions, network, browser, PDF, search, memory. 220 pure-CPU tools run free here (proof-of-work - no wallet needed); the rest need a USDC wallet. There is also an OpenAI-compatible LLM gateway at https://agent402.tools/v1 - flat per-call (chat nano $0.003, auto $0.01, embeddings $0.002), no API key: a funded wallet is the account. Beyond this catalog, Agent402 can ROUTE-AND-EXECUTE against the OPEN x402 ecosystem: POST https://agent402.tools/api/route/execute with { task, include:"external" } resolves a PROVEN external seller (real settled volume), pays it on your behalf, and relays the result (marked untrustedContent) - one call to reach thousands of outside tools, from a $0.01 flat fee. That path is wallet-only, so run it with your own wallet via the HTTP API or the stdio agent402-mcp package's route_and_execute tool (this hosted connector holds no wallet). Returns { results, workflows } - each result has slug, price, access, description, inputSchema; run one with call_tool.
