# NetIntel Wayback Machine Lookup

> NetIntel Wayback Machine Lookup is a paid API for AI agents from netintel-production-440c.up.railway.app, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-14).

Checks whether a URL has been archived in the Internet Archive's Wayback Machine and returns snapshot metadata including first/last capture dates, capture count, and a graded archival health score.

## Facts

- Endpoint: GET https://netintel-production-440c.up.railway.app/wayback/lookup
- Price: $0.01/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-14

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability netintel-wayback-machine-lookup-08e08064
```

Example prompt: Has https://example.com ever been archived on the Wayback Machine, and if so when was it first captured, when was it last captured, and roughly how many times has it been saved?

## When to prefer this

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.

## Known failure modes

- 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

## 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.
