--- name: x402.silverbackdefi.app description: x402.silverbackdefi.app provides five on-demand DeFi intelligence endpoints covering token security auditing, swap quote retrieval, liquidity pool analysis, technical analysis, and yield opportunity discovery. All skills return single-shot snapshots rather than streaming data, and none execute transactions. Coverage spans EVM chains (including Base) and Solana for select skills. host: x402.silverbackdefi.app --- # x402.silverbackdefi.app Silverback DeFi is a research and pre-trade intelligence host targeting autonomous agents that need structured DeFi data before acting. It covers the core due-diligence loop: verify a token is safe, check a swap quote, assess pool health, read technical signals, and find yield. It does not execute trades, stream prices, or audit non-token contracts. Its skills are complementary enough to support multi-step pre-trade workflows within a single host. ## When to use this host Use this host when an agent needs structured pre-trade or pre-allocation intelligence on EVM tokens: security audits, swap quotes on Base or other EVM chains, pool health snapshots, TA signals for CoinGecko-listed assets, or yield opportunity discovery. Do not use it for real-time price streaming (use a dedicated price oracle or DEX data feed instead), transaction execution (use an on-chain execution layer or wallet API), auditing non-token smart contracts (use a general contract auditor), or Solana swap quotes (use a Solana-native quote API such as Jupiter). If an agent only needs a spot price with no pool or trade context, this host is not the right choice. ## Capabilities ### Token Security Assesses the safety of a token contract before any trading or allocation decision, detecting honeypots, tax traps, minting risks, and ownership status. - **`audit-token-security`** — Performs a smart-contract security audit for an ERC or SPL token, returning honeypot detection, tax analysis, ownership risks, and a numeric risk score. ### Swap Intelligence Retrieves an optimal EVM swap quote including expected output, price impact, route, and gas estimate without submitting any transaction. - **`fetch-swap-quote`** — Returns an optimal EVM token swap quote including amountOut, minAmountOut, price impact, fee, route, router address, estimated gas, and liquidity availability for a given token pair and input amount. ### Liquidity Pool Analysis Delivers a snapshot of a specific pool's TVL, APR, volume, reserve composition, and health score across EVM and Solana chains. - **`analyze-liquidity-pool`** — Returns TVL, APR, health score, liquidity rating, trading volume, and reserve data for a specified EVM or Solana liquidity pool. ### Technical Analysis Provides on-demand TA signals — RSI, EMAs, Bollinger Bands, chart patterns, support/resistance, and a directional recommendation — for any CoinGecko-listed token. - **`fetch-technical-analysis`** — Returns RSI, MACD-adjacent EMAs, Bollinger Bands, liquidity sweep patterns, chart patterns, trend conditions, momentum signals, and support/resistance levels for a CoinGecko token over a chosen timeframe. ### Yield Discovery Surfaces multi-chain DeFi yield opportunities for a given token filtered by risk tolerance, including APR breakdowns, impermanent loss estimates, and an allocation strategy. - **`fetch-defi-yield-opportunities`** — Returns multi-chain DeFi yield opportunities for a given token, including APR breakdowns, risk scores, impermanent loss estimates, an optimal allocation strategy, and market insights. ## Workflows ### Pre-Trade Due Diligence *Use when an agent needs to safely evaluate and size a token swap — verifying the token is not a honeypot, confirming acceptable price impact, and reading market momentum before committing.* 1. **`audit-token-security`** — Verify the target token has no honeypot flags, acceptable tax rates, and safe ownership status before proceeding. 2. **`fetch-technical-analysis`** — Check trend direction, momentum score, and key support/resistance levels to confirm the trade aligns with current market conditions. 3. **`fetch-swap-quote`** — Retrieve the expected output amount, price impact, and optimal route for the intended swap size. ### Yield Opportunity Vetting *Use when an agent needs to identify and validate a DeFi yield position — finding candidate pools, then verifying pool health and token safety before allocating.* 1. **`fetch-defi-yield-opportunities`** — Discover current yield opportunities for the target token filtered by the agent's risk tolerance. 2. **`analyze-liquidity-pool`** — Validate the health score, TVL depth, and volume of the top candidate pool before committing capital. 3. **`audit-token-security`** — Confirm the underlying token contract is safe and free of minting or ownership risks that could affect the yield position. ## Skill reference ### `analyze-liquidity-pool` **PoolSight Liquidity Pool Analysis** — Returns TVL, APR, health score, liquidity rating, trading volume, and reserve data for a specified EVM or Solana liquidity pool. *Use when:* Use when an agent needs detailed metrics on a specific liquidity pool — including TVL, fee APR, 24h volume, buy/sell activity, and a health score — given a pool address or token pair. *Not for:* Do not use for streaming price feeds or real-time tick data; this is a single-shot pool snapshot. Not suitable for fetching token prices without a pool context — use a price oracle API instead. **Inputs:** - `tokenA` (string) — First token of the pair — EVM address (0x) or symbol. - `tokenB` (string) — Second token of the pair — EVM address (0x) or symbol. - `poolId` (string) — Direct pool contract address if known; overrides tokenA/tokenB lookup. - `chain` (string) — Chain name to scope the lookup (e.g. 'base', 'ethereum', 'solana'). - `baseToken` (string) — Address of the base token for price quoting. - `quoteToken` (string) — Address of the quote token for price quoting. - `riskProfile` (string) — Risk profile for analysis framing; observed value: 'balanced'. - `benchmarkSizeUsd` (number) — Trade size in USD used to benchmark slippage and price impact calculations. - `liquidityWindowDays` (integer) — Lookback window in days for liquidity and volume metrics. - `include` (array) — List of analysis modules to include. Observed values: crossChainRoutes, liquidityDepth, priceImpact, slippageAtSize, TVLAndConcentration, volumeAndFeeAPR, oracleAndDeviationRisk, poolHealth, bridgeAndLiquidityRisks. **Returns:** Returns success=true with pool pair address, DEX name, token reserves, TVL ($1.42M), liquidity rating (EXCELLENT), fee (0.3%), 24h volume, buy/sell activity counts, and a health score (95) for the Base WETH/USDC pool. **Example:** `{"chain":"base","tokenA":"0x4200000000000000000000000000000000000006","tokenB":"0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913","include":["poolHealth","TVLAndConcentration","volumeAndFeeAPR"]}` --- ### `fetch-technical-analysis` **Technical Pulse — Crypto TA** — Returns RSI, MACD-adjacent EMAs, Bollinger Bands, liquidity sweep patterns, chart patterns, trend conditions, momentum signals, and support/resistance levels for a CoinGecko token over a chosen timeframe. *Use when:* Use when an agent needs on-demand technical analysis for a crypto asset — including trend direction, momentum score, bullish/bearish recommendation, and key support/resistance levels — before making or advising on a trade. *Not for:* Do not use for real-time streaming price feeds or order execution; this is a single-shot TA snapshot. Not suitable for tokens not listed on CoinGecko by their CoinGecko ID. **Inputs:** - `token` (string, required) — CoinGecko token ID for the asset to analyze (e.g. bitcoin, ethereum, solana). - `timeframe` (string) — Analysis period in days; accepted values are 1, 7, 14, or 30. Defaults to unspecified if omitted. **Returns:** Returns success=true with a data object containing EMA9/EMA21/RSI/Bollinger Bands indicators, liquidity sweep and chart pattern detections, market regime, trend/momentum conditions, a BULLISH/BEARISH/NEUTRAL recommendation, and pivot/support/resistance price levels. **Example:** `{"token": "bitcoin", "timeframe": "7"}` --- ### `fetch-swap-quote` **Silverback Swap Quote** — Returns an optimal EVM token swap quote including amountOut, minAmountOut, price impact, fee, route, router address, estimated gas, and liquidity availability for a given token pair and input amount. *Use when:* Use when an agent needs a non-executing swap quote for an EVM token pair (e.g. on Base) to determine expected output amount, price impact, and route before committing to a swap transaction. *Not for:* Do not use to execute a swap — this endpoint returns a quote only and does not submit any transaction. Not verified for Solana pairs; use a Solana-native quote API for SPL token swaps. **Inputs:** - `tokenIn` (string, required) — Input token address (0x format) or symbol (e.g. WETH, USDC). - `tokenOut` (string, required) — Output token address (0x format) or symbol. - `amountIn` (string, required) — Input amount in human-readable units (not atomic/wei). - `chain` (string) — Chain identifier for the swap (e.g. 'base'). - `receiver` (string) — Recipient wallet address for the swap output. - `slippageBps` (integer) — Slippage tolerance in basis points (1 bps = 0.01%). - `affiliateCode` (string) — Affiliate code for tracking or fee-sharing purposes. **Returns:** Returns success=true with a data object containing amountOut, minAmountOut, priceImpact, fee, route array, router address, aggregator name, estimatedGas, liquidityAvailable flag, and a timestamp for the quoted Base chain token pair. **Example:** `{"tokenIn": "0x4200000000000000000000000000000000000006", "tokenOut": "0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913", "amountIn": "1.0", "chain": "base", "slippageBps": 50}` --- ### `fetch-defi-yield-opportunities` **YieldPulse DeFi Yield Opportunities** — Returns multi-chain DeFi yield opportunities for a given token, including APR breakdowns, risk scores, impermanent loss estimates, an optimal allocation strategy, and market insights. *Use when:* Use when an agent needs current DeFi yield rates and pool options for a specific token (e.g. USDC, WETH) filtered by risk tolerance, including protocol-level APR data and a recommended portfolio allocation. *Not for:* Do not use for real-time price feeds or token swap execution; this endpoint returns yield intelligence only, not executable transactions or live spot prices. **Inputs:** - `token` (string) — Token symbol (e.g. USDC, WETH, SOL) or contract address to query yield opportunities for. - `riskTolerance` (string) — Risk level filter for returned opportunities. Accepted values: low, medium, high. Defaults to medium. **Returns:** Returns success=true with up to hundreds of yield opportunities per token (APR, TVL, risks, IL estimates), an optimal multi-protocol allocation strategy, and market insight summaries including best stable and volatile yields. **Example:** `{"token": "USDC", "riskTolerance": "medium"}` --- ### `audit-token-security` **TokenShield Audit** — Performs a smart-contract security audit for an ERC or SPL token, returning honeypot detection, tax analysis, ownership risks, and a numeric risk score. *Use when:* Use when an agent needs to assess the security posture of a token contract before trading, listing, or recommending it — specifically to detect honeypots, minting risks, ownership renouncement status, and buy/sell tax rates. *Not for:* Do not use for auditing arbitrary smart contracts that are not tokens; this endpoint is scoped to token contracts. Not suitable for real-time price feeds or liquidity data. **Inputs:** - `token` (string, required) — Token contract address to audit. - `chainId` (number) — Chain ID of the network where the token is deployed. Defaults to 8453 (Base). **Returns:** Returns success=true with a data object containing security flags (isHoneypot, isMintable, etc.), trading tax rates, ownership details, a riskScore of 0–100, a riskLevel string, and a warnings array. **Example:** `{"token": "0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913", "chainId": 8453}` ---
