Pay-per-call data tools for AI agents: crypto signal, web reader, SEO audit. x402 USDC on Base.
If you already use Agent, the agent mcp server is the piece that lets your assistant work with it directly. Pay-per-call data tools for AI agents: crypto signal, web reader, SEO audit. x402 USDC on Base.
Pay-per-call data tools for AI agents, settled per call in USDC on Base via the x402 protocol. The buyer is another agent: it discovers an endpoint, auto-pays per request (HTTP 402 → payment → data), and gets structured JSON back. No API key, no signup, no account — the seller's only setup is one public wallet address.
The toolset is worth reading before you wire it up, because it tells you what the integration is really for:
market_signal — GET /signalweb_read — GET /extractrepo_audit — GET /audit?owner=&repo=PAY_TO on npm is all you need. Most clients run it directly, so configuration is a few lines and a restart.
Configuration is passed through the environment: CDP_API_KEY_ID, CDP_API_KEY_SECRET. Treat anything key-shaped as a real credential — scope it to the minimum the server needs, and rotate it if it ever lands in a shared config.
Plenty of developer tooling servers cover similar ground. The differences that matter in practice are scope of access and how much setup stands between you and a working tool call. Agent's toolset — market_signal, web_read, repo_audit — is a fair guide to whether it matches your workflow. It is maintained by dev.charliemorrison; worth a glance at recent repository activity before you build anything load-bearing on it.
We check each listing at SyncDev against the project's documentation before it goes live — if something here drifts out of date, it is a bug worth reporting.
