# Solana Token Holder Concentration Analyzer

> Solana Token Holder Concentration Analyzer is a paid API for AI agents from api.agentstools.dev, paid per call via x402, $0.02/call, status unknown (last checked 2026-10-13).

Returns top holder concentration metrics (top1/5/10%), HHI index, and free-float cap table for a Solana SPL token, excluding bonding-curve, AMM pool vaults, and incinerator accounts.

## 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 solana-token-holder-concentration-analyzer-e4bd3733
```

Example prompt: Can you check the holder concentration for this pump.fun token — mint address 6xdT2nzgbPd9bBrWXwWHEMh5RnLkDvCXXXXXXXXpump — and tell me the top10 percentage, the HHI score, and whether there's a low-float warning?

## When to prefer this

Choose this endpoint when you need accurate free-float holder concentration for a Solana SPL token, especially pump.fun memecoins, and want bonding-curve accounts, AMM pool vaults, and the incinerator automatically excluded so whale concentration reflects real tradeable supply. Prefer it over raw RPC holder queries when you need ready-to-use HHI and top-N percentage metrics without post-processing.

## Known failure modes

- Invalid or malformed mint address (non-base58, wrong length) — returns 400 with validation error
- Token mint not found on-chain — returns 404 or empty holder list
- Unsupported launchpad layout — bonding-curve exclusion may fail for non-pumpfun launchpads
- RPC/upstream Solana node timeout — returns 503 or timeout error
- Payment not attached or insufficient — returns 402 Payment Required

## How this service works

Solana token cap-table: the top holders with amounts and percentages, where the bonding-curve account, AMM/DEX pool vaults and the incinerator are LABELLED and EXCLUDED so real concentration is measured over the free float. Returns top1/top5/top10 percent of circulating, an HHI concentration index and a low-float warning.

## Output

Returns a ranked list of the top token holders with their wallet addresses, token amounts, and percentage of circulating supply — with bonding-curve accounts, AMM/DEX pool vaults, and the incinerator address labeled and excluded so concentration is measured over true free float. Also returns aggregated top1/top5/top10 percentages, an HHI (Herfindahl–Hirschman Index) concentration score, and a boolean low-float warning flag.
