Description from the maker (original English)
Arc gateway for agents: token checks, swaps, the ERC-8004 directory, agent boxes, accounts. x402
These three are never merged into one score: opinions, measurements and popularity are different things.

Tool names and descriptions exactly as the server reported them on Nov 7, 2026. The maker wrote them, not us; we show them as plain text.
tradeSearchResolves a ticker, name, prefix or `0x` address to candidate ERC-20 tokens on Arc. - **Cost:** 0.005 USDC per call, paid over x402. - **Inputs:** `query` (required), `limit` (1-25, default 10), and the optional filters `launchpad` and `launchpadKind`. A filter narrows `results` o
