@true402.dev/ai-sdk

  Stable · production-ready — semver-stable public API (v1.0).

true402 tools for the Vercel AI SDK — give your Base agent pay-per-call on-chain safety over x402: rug/honeypot checks, address safety, and deployer reputation. No account, no API key — the wallet is the identity (USDC on Base, gas sponsored by the facilitator).

npm i @true402.dev/ai-sdk ai

import { generateText } from 'ai';
import { true402Tools } from '@true402.dev/ai-sdk';

const { text } = await generateText({
  model,
  prompt: 'Is 0x4ed4…Efed safe to ape into?',
  tools: true402Tools({ payerPrivateKey: process.env.PAYER_PRIVATE_KEY! }),
});

The model can call, before it trades:

| Tool | What it does | ~price | |---|---|---| | true402_token_report | Composite avoid / caution / ok verdict for a Base ERC-20 (buy/sell honeypot sim + liquidity + ownership + rug activity) | $0.01 | | true402_token_safety | Structural safety score 0–100 + flags | $0.005 | | true402_address_safety | Profile + risk for any address before you send/approve/call it (proxy detection) | $0.005 | | true402_deployer_check | Deployer reputation — who made the token + their track record | $0.008 |

payerPrivateKey is a Base wallet holding a little USDC. Without it the stalls still return their HTTP 402 price, so the agent can decide. Override baseUrl / rpcUrl in the options if self-hosting.
