Framework guides for x402-guard

Copy-paste guides for plugging MoneyTools payment checks into the HTTP client your agent already uses. Until npm / PyPI are published, each guide installs from the download URL.

Vercel AI SDK — Wrap the official x402 client before a Vercel AI SDK tool pays a seller.
LangChain (JS and Python) — Same hook in a LangChain JS or Python tool that calls a paid HTTP endpoint.
Apify mcpc — Pre-check a paid MCP server before mcpc connects or signs an x402 payment.
Coinbase AgentKit — Attach the guard to the x402Client AgentKit already uses before it signs.
ElizaOS — Gate x402 payments from an ElizaOS action with the official client hook.
OpenAI Agents SDK — Use a guarded paying fetch inside an OpenAI Agents SDK function tool.

After publish: npm install @moneytools/x402-guard · pip install moneytools-x402-guard

Pricing: install is free; checks are 0.005 USDC via x402 after the live free tier. The guard never loads a key or sends a payment.

Install is free. Checks are billed per call at 0.005 USDC via x402 after the live free tier (Pay Precheck: 5/IP/endpoint/day; Settle: trial 50 calls / 7 days; Approval Relay: 3/day). The guard never loads a key, never signs, and never pays MoneyTools automatically. Docs: https://moneytools.dev/products/payment-safety/
