Pay-per-use token security audit — honeypot detection, tax analysis, and ownership risk scoring via x402 micropayments.
What it does
The Silverback Token Audit endpoint performs a comprehensive security audit on any ERC-20 token contract. It checks for honeypot behavior, analyzes buy/sell taxes, evaluates ownership and renouncement 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 in the Silverback x402 API suite. Payment is $0.02 per call, settled in USDC on Base, Solana, or SKALE via the x402 micropayment protocol. Callers first receive a 402 Payment Required response with payment instructions, sign a USDC authorization, and resend with the payment proof header to receive the JSON result.
The API accepts POST requests with a JSON body containing the token contract address and an optional chain ID. All responses include a `success` boolean field. The broader Silverback platform also offers swap execution, technical analysis, DeFi yield intelligence, arbitrage scanning, whale tracking, wallet portfolio lookup, pool analysis, swap quotes (Base and Solana via Jupiter), and holder analytics — each priced between $0.01 and $0.05 per call.
Capabilities
Use cases
- —Screening a new token before buying to check for honeypot or high-tax traps
- —Automated agent pipelines that gate swap execution on a passing security audit
- —Portfolio dashboards that flag risky holdings with ownership and tax warnings
- —Due diligence on token launches by checking renouncement status and contract risks
Fit
Best for
- —AI agents that need programmatic token safety checks before trading
- —DeFi bots requiring pre-trade security screening on Base or other EVM chains
- —Developers building token screening UIs with pay-per-use pricing
Not for
- —Full smart-contract source-code audits or formal verification
- —Non-EVM chains (Solana token audits are not indicated for this endpoint)
- —High-volume bulk scanning without per-call micropayment budget

}Endpoint
Quality
Full OpenAPI schema with clear endpoint description, pricing, and request parameters. 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 was empty, so payment details (asset address, network, amount in base units) could not be independently verified from the probe.
Warnings
- —External docs URL (https://docs.silverbackdefi.app/) was not crawled; the /docs path on the server returns 404.
- —The 402 challenge object captured in the probe was empty — payment parameters (asset, network, exact amount) could not be independently verified.
- —No example response schema is provided; response structure is inferred from the summary only.
- —The endpoint is hosted on Render free/hobby tier (onrender.com) which may have cold-start latency.
