# madeonsol KOL Affinity Matrix

> madeonsol KOL Affinity Matrix is a paid API for AI agents from madeonsol.com, paid per call via x402, $0.02/call, status unknown (last checked 2026-10-28).

Returns a ranked list of KOL (Key Opinion Leader) pairs who frequently co-trade the same Solana tokens, exposing coordinated or correlated trading behavior.

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 madeonsol-kol-affinity-matrix-33aae618
```

Example prompt: Show me the top 20 KOL pairs on Solana who most frequently co-trade the same tokens over the last 30 days, with at least 5 shared tokens between them.

## When to prefer this

Use this endpoint when you need to identify which Solana KOLs move together — for detecting coordinated trading rings, mapping influencer clusters, or finding high-conviction token plays where multiple KOLs overlap. Prefer this over single-KOL wallet analysis endpoints when the research question is about relationships between influencers rather than individual behavior.

## Known failure modes

- No pairs found for the requested min_shared threshold — returns empty pairs array
- Invalid period value (outside '7d'/'30d' enum) — likely 400 error
- limit out of range (< 1 or > 50) — validation error
- Payment failure or 402 not resolved — endpoint inaccessible
- Stale or delayed data if underlying KOL trade index hasn't refreshed recently

## How this service works

KOL affinity matrix — which KOLs frequently co-trade the same tokens

## Output

A JSON object with a 'pairs' array, where each entry represents two KOLs and metadata about their co-trading relationship, including the count of tokens they both traded within the selected window and their affinity ranking. The list is bounded by the 'limit' parameter and filtered by 'min_shared'.
