Pay-per-use DeFi trending tokens endpoint via x402 micropayments on Base, Solana, and SKALE.
What it does
Silverback is a DeFi intelligence API suite that uses the x402 micropayment protocol for pay-per-use access. The `/api/v1/trending-tokens` endpoint is one of 11 paid endpoints offered by Silverback, though it is notably absent from the published OpenAPI specification which documents the other endpoints. The endpoint returned 404 on both GET and POST probes, suggesting it may not be currently live or may have been renamed/removed.
The broader Silverback API provides DeFi intelligence services including token swaps via Permit2, technical analysis (RSI, MACD, Bollinger Bands), DeFi yield opportunities, 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. Payments are made in USDC on Base, Solana, or SKALE, with pricing ranging from $0.01 to $0.05 per call depending on the endpoint tier. A 15% discount is available when paying with the $BACK token via Permit2 on Base.
Because the specific `/api/v1/trending-tokens` endpoint returned 404 and is not documented in the OpenAPI spec, its exact request/response schema and pricing are unknown. It may have been deprecated or consolidated into another endpoint. Agents should check the discovery endpoint at `/discovery/resources` or the pricing endpoint at `/api/v1/pricing` for current availability.

Quality
The specific /api/v1/trending-tokens endpoint returned 404 on both GET and POST probes and is not documented in the published OpenAPI spec. While the broader Silverback API is well-documented with 11 other endpoints, this particular endpoint appears unavailable or undocumented, making it effectively a stub listing.
