Pay-per-use DeFi correlation matrix analysis via x402 micropayments on Base, Solana, and SKALE.
What it does
Silverback's correlation-matrix endpoint is part of the Silverback x402 DeFi Intelligence API, which provides autonomous DeFi infrastructure for the agent economy. The API suite offers 11 pay-per-use endpoints covering swap routing, liquidity analysis, yield optimization, technical analysis, and market data. Payments are made via the x402 micropayment protocol using USDC on Base, Solana, or SKALE (with a 15% discount available using the $BACK token via Permit2 on Base).
The `/api/v1/correlation-matrix` endpoint is not documented in the published OpenAPI spec, which covers 11 other endpoints but does not include this one. During probing, the endpoint returned 404 on both GET and POST, suggesting it may have been removed, renamed, or is not yet deployed. The broader Silverback API platform is live (root returns 200, and the OpenAPI spec is well-structured), but this specific endpoint could not be confirmed as operational.
Other endpoints in the Silverback suite range from $0.01 to $0.05 per call and cover technical analysis (RSI, MACD, Bollinger Bands), DeFi yield intelligence, cross-DEX arbitrage scanning, token security audits, whale transaction tracking, wallet portfolio lookups, liquidity pool analysis, swap quotes, Jupiter DEX quotes on Solana, and holder analytics. All responses return JSON with a `success` boolean field. Token identifiers use CoinGecko IDs for market data or contract addresses for on-chain endpoints.
