Pay-per-use DeFi pool ranking endpoint via x402 micropayments on Base, Solana, and SKALE.
What it does
The `/api/v1/top-pools` endpoint is part of the Silverback x402 DeFi Intelligence API, a suite of 11 pay-per-use endpoints providing DeFi analytics and execution services. Silverback uses the x402 micropayment protocol, accepting USDC on Base, Solana, and SKALE networks. While this specific endpoint is not individually documented in the OpenAPI spec, the broader API covers liquidity pool analysis, swap routing, yield optimization, technical analysis, whale tracking, and more.
The Silverback API is designed for autonomous agents and applications in the DeFi ecosystem. Endpoints follow a consistent pattern: an initial request returns a 402 Payment Required challenge with payment options, the caller signs a USDC authorization via x402, and the paid request returns JSON data. The `/api/v1/top-pools` endpoint likely returns ranked liquidity pool data, complementing the documented `/api/v1/pool-analysis` endpoint which provides deep pool analysis with TVL, APR, and health scoring at $0.01 per call.
Note: During probing, this specific endpoint returned 404 on both GET and POST methods, meaning it may have been renamed, removed, or requires a different request format than was tested. The root landing page at the origin is live (HTTP 200), and the broader Silverback API infrastructure appears operational. Pricing for analysis-tier endpoints in this API is $0.01 per call.
Capabilities
Use cases
- —Discovering the highest-TVL or highest-APR liquidity pools across DEXes
- —Screening pools for an automated yield-farming agent
- —Building a DeFi dashboard that ranks pools by performance metrics
- —Identifying new liquidity opportunities for portfolio allocation
Fit
Best for
- —AI agents needing programmatic access to ranked DeFi pool data
- —Developers building DeFi aggregation or analytics tools
- —Autonomous trading bots scanning for liquidity opportunities
Not for
- —Users needing free or subscription-based unlimited access to pool data
- —Non-crypto applications with no DeFi context
- —Real-time sub-second trading where micropayment latency is unacceptable
Quick start
# Attempt to discover payment challenge (x402 protocol)
curl -X GET https://x402.silverbackdefi.app/api/v1/top-pools
# Expected: 402 with payment options, then re-send with x402 payment proof headerEndpoint
Quality
This specific endpoint (/api/v1/top-pools) returned 404 on both GET and POST probes, and it is not listed in the OpenAPI spec. The broader Silverback API is documented with 11 endpoints, but top-pools is absent. The endpoint may be deprecated, renamed, or require undocumented parameters. Listing is largely inferred from sibling endpoints.
