给加密开发者、交易者、协议方用的链上情报服务：这个地址是谁？这笔交易做了什么？这组地址是不是同一伙人？
| 接口 | 作用 | 价格 |
|---|---|---|
GET /v1/label/{address} | Address tag lookup on Base: 104,209 entries from the open eth-labels dataset, mostly category tags (79.8% generic such as token-contract/stablecoin/burn, 18.7% exchange) rather than named entities. Unknown addresses return label:null and are still charged per call; measured hit rate on real inbound requests was 37.5% of unique addresses. Pay per call with USDC via x402. | 1 credit |
GET /v1/explain/{txHash} | Plain-language explanation of a Base transaction: what happened, who paid whom, which contracts were involved. | 2 credits |
GET /v1/cluster/{funder} | Sybil / funding-cluster analysis: addresses funded by the same funder on Base. | 5 credits |
GET /v1/track/cctp/{txHash} | CCTP cross-chain USDC tracking: given the source-chain tx hash, returns burn/mint status and whether funds arrived on Base. | 3 credits |
GET /v1/alerts | Historical on-chain alerts on Base (filter by address / kind / severity / since). | 1 credit |
GET /v1/alerts/stats | Aggregate statistics over historical on-chain alerts on Base. | 1 credit |
POST /v1/alerts/subscribe | Subscribe an agent to future on-chain alerts on Base, delivered via webhook or Telegram. | 1 credit |
GET /api/filings/8k | Latest US SEC 8-K material-event filings (M&A, executive changes, earnings, delisting, bankruptcy). Live stream from SEC EDGAR. | 1 credit |
GET /api/filings/today | Today’s US SEC 8-K material-event filings (M&A, executive changes, earnings, delisting, bankruptcy), newest first. Same SEC EDGAR live stream as /api/filings/8k, fixed at the 50 most recent filings. | 1 credit |
GET /v1/label | Address tag lookup on Base: 104,209 entries from the open eth-labels dataset, mostly category tags (79.8% generic such as token-contract/stablecoin/burn, 18.7% exchange) rather than named entities. Unknown addresses return label:null and are still charged per call; measured hit rate on real inbound requests was 37.5% of unique addresses. Pay per call with USDC via x402. | 1 credit |

USDC 充值，1 USDC = 100 credits（label 查询约 $0.01/次）。
无需注册、无需付款：用你的 Base 钱包地址作为 Bearer 身份首次调用即自动获得 10 credits 的免费额度，够跑通 10 次地址查询。额度用完后接口返回 402 Payment Required 并附充值指引。
两套免费额度互相独立：钱包试用需带 Bearer 身份，每地址一次性 10 credits；匿名免费层只走 MCP、无需任何身份，按 IP 与工具分别计数，用来先跑通一次调用。
curl -H "Authorization: Bearer <你的地址或API key>" \ https://agentsapi.top/v1/label/0x0000000000001ff3684f28c67538d4d072c22734
发送 USDC（Base 主网）到收款地址 0x381cdbb664608bf7b1dd4f9403a572c1c57332c2，并用同一个地址作为 Bearer 身份调用——链上监听确认到账后约 1 分钟自动入账。
程序化发现：/.well-known/x402（x402 定价 manifest）。
同一套能力也以远程 MCP server 对外提供：https://agentsapi.top/mcp（Streamable HTTP，serverInfo.version 0.3.1，共 7 个工具）。握手与 tools/list 免费；匿名免费层 7 次/日/IP（全站上限 500/日；每个工具各 1 次，共 7 个工具都可试：get_label / explain_transaction / detect_cluster / query_alerts / alert_stats / track_cctp / list_paid_endpoints），无需注册、无需钱包；tools/call 按次计费（x402 payment-signature 或 Bearer/credit），与上方 REST 端点共用同一份定价与收款地址。
机器可读入口：/mcp 端点卡片 · /skill.md agent 使用说明 · /.well-known/mcp.json · mcp-server-card.json · /statusz 实时状态
启用 x402 的部署下，agent 客户可直接在请求头带 X-PAYMENT 按次自动付款（USDC 经 CDP Facilitator 校验，落到上面的收款地址），无需先充值、无最低余额。端点已被 /.well-known/x402 暴露，可被 Agentic.Market 等 agent 市场自动发现与调用。
