Token security audit via x402 micropayment — honeypot detection, tax analysis, and ownership risk scoring.
What it does
The Silverback Token Audit endpoint performs a comprehensive security audit on any ERC-20 token contract. It checks for honeypot characteristics, analyzes buy/sell taxes, evaluates ownership risks, and returns a risk score with detailed warnings. The endpoint defaults to Base (chain ID 8453) but accepts other EVM chain IDs.
This is one of 11 pay-per-use DeFi intelligence endpoints offered by Silverback via the x402 micropayment protocol. Each call costs $0.02 in USDC, payable on Base, Solana, or SKALE. The workflow is standard x402: send a POST request, receive a 402 challenge with payment options, sign a USDC authorization, and resend with the payment proof header to get the JSON response.
The endpoint accepts a token contract address (required) and an optional chainId parameter. Responses include a success boolean along with security audit data such as risk scores, ownership analysis, and specific warnings. It is designed for autonomous agents and applications that need to programmatically evaluate token safety before trading or recommending tokens to users.
Capabilities
Use cases
- —Screening tokens for honeypot or rug-pull characteristics before executing a swap
- —Automated agent pipelines that gate trading decisions on a security risk score
- —Portfolio dashboards that flag risky token holdings for users
- —DEX aggregators adding safety warnings to token listings
- —Research workflows analyzing newly deployed tokens on Base or other EVM chains
Fit
Best for
- —AI agents that need programmatic token safety checks before trading
- —DeFi applications adding automated security screening to their workflows
- —Developers building token risk dashboards or alerts
- —Autonomous trading bots requiring pre-trade security validation
Not for
- —Full smart-contract source-code audits (this is heuristic/on-chain analysis, not formal verification)
- —Non-EVM chains like Solana or Bitcoin (endpoint is EVM-focused)
- —Free or subscription-based access (requires x402 micropayment per call)

}Endpoint
Quality
Full OpenAPI schema with clear endpoint description, request parameters, and pricing. The endpoint is live (402 challenge captured). However, no example response body is documented, the external docs link returns a 404, and the 402 challenge object is empty so exact payment details (token address, amount in base units) are not directly confirmed from the probe.
Warnings
- —External docs URL (https://docs.silverbackdefi.app/) was not crawled; the /docs path on the x402 server returns 404.
- —No example response schema is provided in the OpenAPI spec — response structure is inferred from the summary only.
- —The captured x402 challenge object is empty ({}), so exact payment token/amount details come solely from the OpenAPI x-payment-info annotation rather than a live 402 body.
