name: token-risk-x402 description: >- Use when the agent must pre-screen a crypto token before sizing, quoting or executing a trade on Solana or Base: "check token risk", "is this token safe", "rug check", "honeypot", "mint authority", "LP locked". Paid x402 API with a free tier, no API key needed. version: 1.0.0

Token risk x402 skill

Pre-trade token safety checks for AI agents. Two tools on one origin, https://api.ogenalabs.com. No API key. No signup. Payment is x402 USDC per call, which your wallet or agent framework settles automatically.

What x402 payment looks like

x402 reuses HTTP 402 Payment Required. The flow is always:

  1. POST the endpoint with JSON body, no payment headers.
  2. Read the 402 body: accepts[] lists price, asset, network and payTo.
  3. Sign the payment with a standard x402 v2 client (EIP-3009 authorization on Base, signed transfer on Solana) and base64-encode the PaymentPayload JSON.
  4. Retry the same POST with a payment-signature header carrying that base64 payload.
  5. Read the 200 body plus the base64 PAYMENT-RESPONSE receipt header. Keep the attestation.hmac for your audit trail.

Free tier: the deep report allows 3 free calls per caller per 24 hours. Send any stable x-client-id header to track your quota (x-free-tier-remaining is not used; count your own calls).
