Quickstart

快速开始

Inspect the payment challenge safely.

安全检查付款 challenge。

curl "https://cms.stablehunter.com/api/public/source-intelligence/research-snapshots?topic=payment_api"

Without a valid token, the API returns HTTP 402 and a Payment-Required header. This curl command inspects the challenge without signing a transaction or sending USDC.

如果没有有效 token，API 会返回 HTTP 402 和 Payment-Required header。这条 curl 命令只检查 challenge，不会签名交易或发送 USDC。

Paid quickstart

付费快速开始

Pay once and print the purchased JSON.

付款一次并打印购买的 JSON。

npx awal@latest x402 pay \
  "https://cms.stablehunter.com/api/public/source-intelligence/research-snapshots?topic=payment_api" \
  --max-amount 10000 \
  --json

10000 is 0.01 USDC in atomic units. The command intentionally sends a payment. Success means the JSON contains success: true, access.status: allowed, and the purchased payload. Without --json, the CLI may complete settlement without printing the response body.

10000 个原子单位等于 0.01 USDC。这条命令会主动付款。成功结果的 JSON 应包含 success: true、access.status: allowed 和购买的数据 payload。若不加 --json，CLI 可能完成结算但不打印响应正文。

Agent tool shape

Agent tool 形态

Wrap the endpoint as a tool.

把 endpoint 包成 tool。

async function agentEconomySignals(topic = "payment_api") {
  const res = await fetch(
    `https://cms.stablehunter.com/api/public/source-intelligence/research-snapshots?topic=${topic}`,
    { headers: { "x-source-intelligence-token": process.env.STABLEHUNTER_API_TOKEN } }
  )
  return await res.json()
}
