Pay-per-call data gateway for AI agents — 62 x402 endpoints, USDC on Base, no API key or signup, just a wallet. Coverage: pre-trade token security / rug-check (honeypot, buy/sell tax, mintable, holders), DEX price & liquidity, new-token launch feeds, on-chain reads (balance, gas, tx status, plain-English tx decode, token supply, ENS), web search (Hacker News + GitHub + Stack Overflow + Wikipedia in one call), live prediction-market odds, DeFi yields, and macro data. Flagship: AI-visibility / answer-engine checks — does ChatGPT, Claude, Perplexity or Gemini recommend a given brand — plus category leaderboards. Machine-readable: /openapi.json, MCP server at /mcp, A2A agent card. Payable by both x402 v1 (x402-fetch) and v2 clients.
Pay from $0.01 to $0.49 per request in USDC on Base / Solana, settled onchain via the x402 protocol, no signup, no API key needed.

No deterministic risk flag. Risk fires only on an exact blocklist match, or a reserved-brand name with a mismatched verified payTo. Never from low uptime, a high price, or a model guess.

All charts share the 30d window selected here. Every series is also served as JSON at /api/v1/services/agent-exchange/price, /scores, /volume and /buyers. On-chain volume and distinct buyers are measured over the service's settlement address and are a conservative undercount (only settlements that reach a measured facilitator are counted).
