Output & pipelines

wayparam is designed to be pipeline-safe.

stdout vs stderr

• stdout: machine-readable results (URLs or JSONL) only if --stdout is enabled
• stderr: logs, hints, errors, and optional stats

This prevents accidental mixing of results and diagnostics.

Per-domain files

By default, wayparam writes per-domain files to results/:

• results/<domain>.txt if --format txt
• results/<domain>.jsonl if --format jsonl

Disable file output with --no-files (requires --stdout).

JSONL format

With --format jsonl, each output line is a JSON object, for example:

{"domain":"example.com","url":"https://example.com/search?q=FUZZ","source":"wayback","fetched_at":"2025-12-23T12:00:00+00:00"}

Common pipeline:

wayparam -d example.com --stdout --no-files --format jsonl | jq -r '.url'

Stats

--stats prints per-domain counts to stderr, so your stdout stream remains pure:

wayparam -l domains.txt --stdout --no-files --stats | sort -u > urls.txt
