Solana token holder concentration

Top-holder concentration for a Solana token mint: the 20 largest holders with token account, owner wallet, balance, percent of supply, insider flag and a pool/locker label when the account is a known AMM vault or locker, plus top-1/5/10/20 share, top-10 share excluding labelled pool accounts, insider count, total holder count and supply. Send POST /api/sol-token-holders with the required field mint and pay $0.005 per call over x402 or MPP (there is no free tier). It returns a JSON object with mint, symbol, decimals, supply, totalHolders and 4 more.

Use it to tell a whale-held launch from one whose largest holder is the liquidity pool. Read from RugCheck's public report (the public Solana RPC throttles getTokenLargestAccounts).

Parameters

Example request

curl -i -X POST https://agent402.tools/api/sol-token-holders \
  -H "Content-Type: application/json" \
  -d '{"mint":"JUPyiwrYJFskUPiHa7hkeR8VUtAeFoSYbKedZNsDvCN","limit":10}'

Without payment this returns HTTP 402 Payment Required with the exact price for sol-token-holders; any x402 v2 or MPP client pays it and retries.

From an MCP client

catalog.call {
  "slug": "sol-token-holders",

The hosted connector at https://agent402.tools/mcp needs a payment for sol-token-holders; the stdio package pays it from a wallet or from AGENT402_CREDITS_KEY. Local install: npx -y agent402-mcp.

Errors and behavior

• mint is required. An input the tool rejects returns an HTTP 4xx whose body carries error, tool, expected, required and example, so the caller can correct it.
• A paid call that ends in any status of 400 or above is not charged over x402, MPP or a prepaid credits key: settlement is cancelled when the tool fails. The exception is a Tempo push credential, a transfer the buyer sent before the call: it settles before the tool runs, so if the tool then fails the payment is recorded as a refund owed to the paying wallet.
• Wallet-only: this tool reaches the network or stored state, so it has no proof-of-work tier. A prepaid card-credits key (Authorization: Bearer a402_...) also pays it.
• A GET or HEAD to /api/sol-token-holders returns the same 402 quote, so the price can be read without a body.
• An Idempotency-Key header makes a retried paid call replay the first 200 instead of charging again (an answer larger than 1 MB is not replayed).

Paid call (JavaScript agent)

import { wrapFetchWithPayment } from "@x402/fetch";
import { x402Client } from "@x402/core/client";
import { registerExactEvmScheme } from "@x402/evm/exact/client";
import { privateKeyToAccount } from "viem/accounts";

const client = new x402Client();
client.setSpendControls?.(false); // keep your own spending ceiling in code
registerExactEvmScheme(client, { signer: privateKeyToAccount(KEY) });
const payFetch = wrapFetchWithPayment(fetch, client);

const res = await payFetch("https://agent402.tools/api/sol-token-holders", {
  method: "POST",
  headers: { "Content-Type": "application/json" },
  body: JSON.stringify({
    "mint": "JUPyiwrYJFskUPiHa7hkeR8VUtAeFoSYbKedZNsDvCN",
    "limit": 10
  }),
});
