How this service works
Network intelligence API — 138 endpoints, all pay-per-call via x402 micropayments (USDC on Base or Solana mainnet). NetIntel is agent fair-trade aligned: transparent per-call pricing in USDC on Base or Solana via x402, no API keys or signup, and automatic no-charge on server errors, upstream failures, and input-validation rejections — failed calls are never billed across NetIntel's network, domain, and data-intelligence endpoints.
Output
Returns a JSON object with: whether the URL is archived (is_archived boolean), a letter grade (e.g. 'A') and numeric score (0-100) reflecting archival health, the closest snapshot object (with a direct Wayback Machine URL, HTTP status, and formatted timestamp), estimated total capture count, first and last capture dates, and any notable findings from the archival analysis.
Example use cases
Example prompt
“Has https://example.com ever been archived on the Wayback Machine, and if so when was it first captured, when was it last captured, and roughly how many times has it been saved?”
Technical details
Endpoint
GEThttps://netintel-production-440c.up.railway.app/wayback/lookupWhen to prefer
Use this endpoint when you need to verify historical web presence of a URL, check archival completeness with a graded score, or find the closest snapshot to a specific historical date. Prefer this over direct Wayback Machine CDX API queries when you want a structured, graded response with capture statistics rather than raw CDX data, and when pay-per-call micropayment cost ($0.01 USDC) is acceptable.
Side effects
- URL not yet archived — is_archived returns false with no snapshot data
- Invalid or malformed URL input causes a 400-level error
- Timestamp provided in wrong format (not YYYYMMDD or YYYYMMDDHHmmss) may return unexpected results
- Wayback Machine API unavailable or rate-limited causes upstream timeout
- Payment not completed (x402 micropayment fails) — returns 402 Payment Required before processing
