Data APIs

Use cached endpoint observations, historical FillPoint station proximity and an off-grid solar energy-balance calculator with explicit provenance and limits.

Know the limits

Endpoint evidence must be fresh and publicly listed; unknown is not paid delivery proof. FillPoint is a September 17, 2026 historical snapshot, not current availability. Solar output is arithmetic, not weather, electrical design or installation certification. Scout discovery is not generally enabled.

A 30-second integration

Examples use placeholders. Plain requests to paid tools return a payment challenge, not a paid result. Free Lint can perform an unpaid public probe. Inspect the response status and evidence scope before using any result.

curl

curl -i https://api.spendpreflight.com/v1/endpoint \
  -H 'Content-Type: application/json' \
  -d '{"url":"https://api.example.com/data"}'

MCP

Connect to https://api.spendpreflight.com/mcp. Call the existing tool:

{
  "name": "check_endpoint",
  "arguments": {
    "url": "https://api.example.com/data"
  }
}

SDK / JavaScript

Use standard fetch alongside the SpendPreflight SDK; the example does not invent a dedicated exported method.

// Node.js SDK integration: use your explicitly budgeted fetch.
// Plain fetch below never signs or pays. There is no dedicated
// spendpreflight SDK helper for this operation.
const response = await fetch('https://api.spendpreflight.com/v1/endpoint', {
  method: 'POST', headers: { 'Content-Type': 'application/json' },
  body: JSON.stringify({"url":"https://api.example.com/data"})
});
console.log(response.status, await response.text());
