# sol-token-holders

> sol-token-holders is a paid API for AI agents from payai.agentstools.dev, paid per call via x402, $0.02/call, status unknown (last checked 2026-10-13).

Returns the Solana SPL token cap table with top holder concentration metrics (top1/top5/top10% of free float), HHI index, and low-float warning after excluding bonding-curve, AMM/DEX pool vaults, and incinerator accounts.

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 sol-token-holders-f4954648
```

Example prompt: Can you check the real holder concentration for this pump.fun token — mint address 6xkFMQBJZNpCXp9fBqXBKQmK8j3iT2rPo7cBsXNvpump — and tell me the top 10 holder percentage, HHI index, and whether there's a low-float warning? Make sure to exclude the bonding-curve and DEX pool accounts.

## When to prefer this

Use this endpoint when you need free-float-accurate holder concentration for a Solana SPL token, especially pump.fun mints, and want bonding-curve, DEX vault, and incinerator accounts automatically excluded so concentration metrics reflect real human wallets. Prefer this over generic holder APIs when you need HHI scoring and low-float warnings in a single call without manual filtering.

## Known failure modes

- Invalid or malformed mint address returns a 400 error
- Mint address not found on-chain returns empty or null holder data
- Rate limiting or upstream RPC unavailability returns a 5xx error
- Payment not settled via x402 protocol returns 402 Payment Required
- Unknown launchpad type passed to launchpad param returns an error or falls back to default

## 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

A ranked list of real token holders with their amounts and percentage of free-float circulating supply, with bonding-curve accounts, AMM/DEX vault addresses, and the incinerator labeled and excluded. Includes top1, top5, and top10 concentration percentages, an HHI (Herfindahl-Hirschman Index) score indicating how concentrated ownership is, and a boolean low-float warning flag.
