Query top DeFi liquidity pools ranked by TVL across Arbitrum, Base, and Ethereum via x402.
What it does
This x402 endpoint from Nacian Finance is intended to return top liquidity pools ranked by Total Value Locked (TVL) across multiple chains including Arbitrum, Base, and Ethereum. According to the listing description, token ordering in pools is handled automatically — tokens do not need to be specified as token0/token1 in any particular order.
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 offers both a natural-language AI analyzer and API access. Subscription plans range from a free tier (20 credits) to Pro at $30/month (3,000 credits), with on-chain payment options advertised.
However, during probing this specific x402 endpoint returned HTTP 404 on both GET and POST requests rather than the expected 402 Payment Required challenge. This means the endpoint is currently not responding as a live x402 endpoint. The provider's main site at nacian.finance is operational (HTTP 200), and the platform appears actively maintained, but this particular API route may have been moved, renamed, or is not yet deployed. No OpenAPI schema, ai-plugin manifest, or detailed API documentation was found at the crawled URLs. Prospective users should verify endpoint availability directly with Nacian before attempting integration.

Quality
