On-chain due diligence for agents. Pay-per-call via [x402](https://x402.org) (USDC on Base L2) -- no API key, no signup, no rate-limit wall.\n\nPart of the [klymax402](https://klymax402.com) marketplace -- 100 x402 micropayment APIs for AI agents, one wallet, USDC on Base.\n\n## Quickstart -- MCP\n\nAdd to your MCP client config (Claude Desktop, Cursor, ElizaOS, etc.):\n\n```json\n{\n  \"mcpServers\": {\n    \"token-holders\": {\n      \"url\": \"https://token-holders.api.klymax402.com/mcp\"\n    }\n  }\n}\n```\n\n## Quickstart -- HTTP (x402)\n\n```bash\ncurl \"https://token-holders.api.klymax402.com/api/holders?address=0x0000000000000000000000000000000000dEaD\"\n# -> 402 Payment Required, with an x402 payment challenge in the response body\n```\n\nAny x402-aware client ([`@x402/fetch`](https://www.npmjs.com/package/@x402/fetch), [`x402-agent-tools`](https://www.npmjs.com/package/x402-agent-tools), ATXP) handles the 402 -> sign -> retry cycle automatically.\n\n## Tools\n\n| Tool | Method | Path | Price | Description |\n|---|---|---|---|---|\n| `token_get_holder_analysis` | GET | `/api/holders` | $0.012 | Get token holder analysis with concentration metrics |\n| `token_get_holder_analysis` | POST | `/api/holders` | $0.012 | Get token holder analysis with concentration metrics (POST variant) |\n\n### `token_get_holder_analysis`\n\nUse this when you need to analyze token holder distribution and concentration risk. Returns holder metrics in JSON.\n\n**Parameters**\n\n| Name | Type | Required | Description |\n|---|---|---|---|\n| `address` | string | yes | Token contract address (0x...) |\n| `chain` | string | no | Chain: base, ethereum (default: ethereum) |\n\n**Returns**\n\n- `topHolders` -- array of top 10 holders with address, balance, percentage of supply\n- `top10Concentration` -- percentage of total supply held by top 10 wallets\n- `whaleCount` -- number of wallets holding >1% of supply\n- `totalHolders` -- total unique holder count\n- `isConcentrated` -- boolean flag if top 10 hold >50% supply (centralization risk)\n\nExample response:\n\n```json\n{\"topHolders\":[{\"address\":\"0xab...cd\",\"balance\":\"1250000\",\"percent\":12.5}],\"top10Concentration\":45.2,\"whaleCount\":7,\"totalHolders\":15420,\"isConcentrated\":false}\n```\n\n**When to use**: buying a token to assess centralization and whale dump risk. Essential for on-chain due diligence and token research.\n\n**Not for**: token price data (use `token_get_ohlcv_history`), token safety (use `token_check_safety`), liquidity depth (use `dex_analyze_orderbook_depth`).\n\n### `token_get_holder_analysis`\n\nUse this when you need to analyze token holder distribution and concentration risk. Returns holder metrics in JSON. POST variant of token_get_holder_analysis -- same params passed as JSON body instead of query string.\n\n**Parameters**\n\n| Name | Type | Required | Description |\n|---|---|---|---|\n| `address` | string | yes | Token contract address (0x...) |\n| `chain` | string | no | Chain: base, ethereum (default: ethereum) |\n\n**Returns**\n\n- `topHolders` -- array of top 10 holders with address, balance, percentage of supply\n- `top10Concentration` -- percentage of total supply held by top 10 wallets\n- `whaleCount` -- number of wallets holding >1% of supply\n- `totalHolders` -- total unique holder count\n- `isConcentrated` -- boolean flag if top 10 hold >50% supply (centralization risk)\n\nExample response:\n\n```json\n{\"topHolders\":[{\"address\":\"0xab...cd\",\"balance\":\"1250000\",\"percent\":12.5}],\"top10Concentration\":45.2,\"whaleCount\":7,\"totalHolders\":15420,\"isConcentrated\":false}\n```\n\n**When to use**: buying a token to assess centralization and whale dump risk.
