Retrieve top liquidity pools ranked by APR across Arbitrum, Base, and Ethereum via x402 payment.
What it does
This x402-gated endpoint at nacian.finance returns top liquidity pools sorted by APR across multiple EVM chains (Arbitrum, Base, Ethereum). According to the existing listing description, the service calculates APR for liquidity pools, automatically reordering token pairs and accepting price range parameters based on the token0/token1 ratio. For example, if token0 is ETH and token1 is USDC, a valid price range might be 1000–8000.
Nacian is a DeFi analytics platform that provides protocol-level data (TVL, volume, fees, lending rates, liquidations, pool composition, APRs) across 14+ supported networks. The platform supports natural-language queries and structured API access. Pricing for the broader Nacian platform starts at free (20 credits) up to $30/month for Pro plans, though this specific endpoint is intended to be paid per-call via the x402 protocol.
Important caveat: during probing, this endpoint returned HTTP 404 on both GET and POST requests rather than the expected 402 payment challenge. This means the endpoint may have been moved, renamed, or is currently offline. The nacian.finance domain is live and serves the main site, but the specific /api/x402/pools/top-pools-by-apr path does not appear to be responding. No OpenAPI schema or API documentation was found at the crawled URLs (the /docs and /api paths both return 404). Prospective users should verify endpoint availability before integrating.

Quality
The endpoint returned 404 on both GET and POST probes instead of the expected 402 x402 challenge, indicating it is likely offline or moved. No OpenAPI schema, no API documentation, and no example request/response data were found. The listing is essentially a stub based on the existing description and general Nacian site information.
