# DeFi Protocol Fee Rankings > DeFi Protocol Fee Rankings is a paid API for AI agents from api.vextorium.com, paid per call via x402, $0.004/call, status unknown (last checked 2026-10-01). Returns DeFi protocols ranked by fees paid by users over 24h, 7d, and 30d periods, with category classification and 7-day fee trend, optionally filtered by blockchain. ## Facts - Endpoint: POST https://api.vextorium.com/defi-comisiones-pago?utm_source=zero.xyz - Price: $0.004/call - Payment: x402 - Status: unknown - Last checked: 2026-10-01 - Activations on Zero: 0 - Tags: x402 - Canonical page: https://www.zero.xyz/c/defi-protocol-fee-rankings-f3d2c103 - Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_NBcz4SoMfr0xzA_PifxBk Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently. ## How to call it through Zero Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`): ```sh zero fetch --capability defi-protocol-fee-rankings-f3d2c103 -d '' ``` Example prompt: Show me the top 20 DeFi protocols ranked by fees on Ethereum — I want to see which ones have the highest 24h, 7d, and 30d fees and how their fees are trending over the past week. ## When to prefer this Use this endpoint when you need a ranked leaderboard of DeFi protocols by user-paid fees across multiple time horizons (24h, 7d, 30d) with trend data. Prefer this over single-protocol fee lookups when comparing multiple protocols or identifying top earners. Use the chain filter when you only care about a specific blockchain ecosystem. For revenue (protocol-retained fees) rather than gross fees paid, use the companion revenue-ranking endpoint. ## Known failure modes - Invalid or unrecognized chain name returns empty or error response - Limit out of range (below 1 or above 50) causes validation error - DefiLlama data source temporarily unavailable causing upstream timeout - Malformed request body returns 400-level error ## How this service works DeFi protocols ranked by the fees users pay them (24h, 7d, 30d), with category and 7d trend. Optional per chain. High, steady fees = a real business. Live from DefiLlama. ## Output Returns an array of DeFi protocols sorted by fees descending, each with protocol name, category (e.g. Dex, Lending, Liquid Staking), fees in USD for 24h/7d/30d windows, and 7-day percentage change in fees. Also includes optional chain filter echo and any relevant notes. ## Request schema (JSON Schema) ```json { "type": "object", "$schema": "https://json-schema.org/draft/2020-12/schema", "required": [ "input" ], "properties": { "input": { "type": "object", "required": [ "type", "method", "bodyType", "body" ], "properties": { "body": { "required": [], "properties": { "cadena": { "type": "string", "description": "Filter by chain, e.g. Ethereum, Base, Solana, Arbitrum (optional)" }, "limite": { "type": "integer", "maximum": 50, "minimum": 1, "description": "Number of protocols (1-50, default 15)" } } }, "type": { "type": "string", "const": "http" }, "method": { "enum": [ "POST" ], "type": "string" }, "bodyType": { "enum": [ "json", "form-data", "text" ], "type": "string" } }, "additionalProperties": false }, "output": { "type": "object", "required": [ "type" ], "properties": { "type": { "type": "string" }, "example": { "type": [ "object", "null" ], "properties": { "nota": { "type": [ "string", "null" ] }, "cadena": { "type": [ "string", "null" ] }, "protocolos": { "type": [ "array", "null" ], "items": { "type": [ "null", "object" ], "properties": { "categoria": { "type": [ "null", "string" ] }, "protocolo": { "type": [ "null", "string" ] }, "cambio_7d_pct": { "type": [ "null", "number" ] }, "comisiones_7d_usd": { "type": [ "null", "number" ] }, "comisiones_24h_usd": { "type": [ "null", "number" ] }, "comisiones_30d_usd": { "type": [ "null", "number" ] } } } } } } } } } } ``` ## Response schema (JSON Schema) ```json { "type": "json", "example": { "nota": "Comisiones = lo que pagan los usuarios al protocolo.
