# Paxie Matrix - Solana Copy-Leader Wallet Rankings > Paxie Matrix - Solana Copy-Leader Wallet Rankings is a paid API for AI agents from api.paxie.fun, paid per call via x402, $0.05/call, status unknown (last checked 2026-10-14). Returns ranked Solana wallets by replay expected value, showing which wallets are the best copy-trade leaders based on recent big-buy performance and shadow-copy outcomes. ## Facts - Endpoint: GET https://api.paxie.fun/v1/sol/wallets/leaders?utm_source=zero.xyz - Price: $0.05/call - Payment: x402 - Status: unknown - Last checked: 2026-10-14 - Activations on Zero: 0 - Tags: x402 - Canonical page: https://www.zero.xyz/c/paxie-matrix-solana-copy-leader-wallet-rankings-d5313798 - Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_s5Di7PeJT76w8A2zy4g2B 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 paxie-matrix-solana-copy-leader-wallet-rankings-d5313798 ``` Example prompt: Show me the top 20 Solana copy-trade leaders right now — ranked by replay expected value so I can see which wallets are worth shadowing on pump.fun launches. ## When to prefer this Use this endpoint when you need a ranked leaderboard of Solana copy-trade leaders scored by replay expected value, specifically for pump.fun tokens 5 minutes to 4 hours old. Prefer this over generic on-chain analytics when you want pre-computed, regularized EV scores with sell-side statistics and shadow-copy performance metrics, updated every 20 seconds, with no API key required — just pay per call via x402 in USDC. ## Known failure modes - Payment not included or insufficient USDC — returns 402 Payment Required - limit parameter out of range (must be 1-50) — returns 400 Bad Request - No qualifying wallets in scoring window — returns empty wallets array - Data staleness: ageSec may exceed 30s during chain congestion or indexer lag - Network timeout if chain indexer is temporarily unavailable ## How this service works Launch data for Robinhood Chain and Solana, updated every 20 s (≤30 s lag). Robinhood Chain: every ETH-quoted Uniswap v4 and v3 pool created in the last 24 h. Solana: pump.fun tokens 5 min to 4 h old that show curve progress. Buyer bursts, a rug check on who holds each pool's liquidity (per burst, and per token before you buy), new pools, per-minute flow, repeat-buyer crews and copy-leader replays. Robinhood signals are scored 30 minutes later, Solana ones at graduation or 20 minutes, rugs counted. Data, not trading advice. Paid per call with x402 (USDC on Base or Solana); no API keys. Every schema property carries x-available: signal = Known when the burst fires. Safe to use as a feature. signal+seconds = Filled 5-60 s after the signal, computed from chain state as of the signal block. Safe as a feature once present; null until then. signal+30m = Outcome. Exists only after the scoring window closes (Robinhood 30 min; Solana graduation or 20 min). Never use as a feature: a backtest that does uses the future. now = Current state as of the response's generatedAt (or the row's checkedAt). Not tied to a signal. Errors (4xx/5xx) are never charged. /v1 is canonical; the original paid paths are also served unversioned. ## Output A JSON array of up to 50 ranked Solana wallet objects, each containing: wallet address, rank, raw expected value (evRaw), shrunk/regularized EV (evShrunk), number of qualifying buys (n), win share, shadow count, shadow hit rate, last buy timestamp, and optional sell statistics (sold count, observed count, sold share, median sell time in seconds, median sell gain, and share sold within 60 seconds). Also includes chain identifier, schema version, generation timestamp, data age in seconds, and methodology metadata describing the replay EV calculation window and parameters. ## 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" ], "properties": { "type": { "type": "string", "const": "http" }, "method": { "enum": [ "GET" ], "type": "string" }, "queryParams": { "type": "object", "properties": { "limit": { "type": "number", "default": 50, "maximum": 50, "minimum": 1, "description": "Max rows, 1-50 (default 50)" } } } }, "additionalProperties": false }, "output": { "type": "object", "required": [ "type" ], "properties": { "type": { "type": "string" }, "example": { "type": "object", "required": [ "chain", "schemaVersion", "generatedAt", "ageSec", "wallets" ], "properties": { "chain": { "enum": [ "robinhood", "solana" ], "type": "string" }, "ageSec": { "type": "integer" }, "method": { "type": "object" }, "wallets": { "type": "array", "items": { "type": "object", "properties": { "n": { "type": [ "integer", "null" ] }, "rank": { "type": [ "integer", "null" ] }, "evRaw": { "type": [ "number", "null" ] }, "sells": { "type": [ "object", "null" ] }, "wallet": { "type": [ "string", "null" ] }, "evShrunk": { "type": [ "number", "null" ] }, "shadowed": { "type": [ "integer", "null" ] }, "winShare": { "type": [ "number", "null" ] }, "lastBuyAt": { "type": [ "integer", "null" ] }, "shadowHit": { "type": [ "number", "null" ] } } } }, "generatedAt": { "type": "integer" }, "schemaVersion": { "type": "integer" } } … (truncated) ``` ## Response schema (JSON Schema) ```json { "type": "json", "example": { "chain": "solana", "ageSec": 1200, "method": { "minN": 10, "metric": "replay EV per copy: each big buy replayed through the desk copy exits, 60-min path, fees in, capped at +100%", "shrink": { "k": 15, "prior": 0.0119 }, "window": "last 60 big buys per wallet" }, "wallets": [ { "n": 12, "rank": 1, "evRaw": 0.1017, "sells": { "sold": 2, "observed": 3, "soldShare": 0.667, "medSoldSec": 57.5, "medSellGain": 0.16, "soldWithin60sShare": 0.5 }, "wallet": "BUkp7rWm3xQe8YtN2fLd5hJc9vGa4sKo1iPzRb6nTq3E", "evShrunk": 0.0518, "shadowed": 212, "winShare": 0.667, "lastBuyAt": 1791568652000, "shadowHit": 0.509 }, { "n": 30, "rank": 2, "evRaw": -0.024, "sells": null, "wallet": "9vRq2LxT7mWc4Kd8YbN3pFh6sJa1eGu5oZiQ2rXtMwPk", "evShrunk": -0.012, "shadowed": 64, "winShare": 0.4, "lastBuyAt": 1791567392000, "shadowHit": 0.328 } ], "generatedAt": 1791569012000, "schemaVersion": 1 } } ``` ## More - Live health (JSON, refreshed every minute): https://www.zero.xyz/c/paxie-matrix-solana-copy-leader-wallet-rankings-d5313798/health.json - [Zero catalog index](https://www.zero.xyz/llms.txt) - [Other services from api.paxie.fun](https://www.zero.xyz/host/api.paxie.fun/llms.txt)
