Collector mode

Use an AI agent to collect structured web data as JSON and CSV.

Collector mode is an interactive REPL mode for data collection tasks. Instead of generating an API client from a HAR, it runs a Claude-powered collector that uses web search and fetch tools, writes collected items, and exports structured artifacts.

When to use it

You want a dataset, not a reusable API client.
The task is research or aggregation across multiple web pages.
JSON/CSV output is more useful than generated request code.

How to run it

Direct:

reverse-api-engineer collector \
  --prompt "collect companies hiring browser automation engineers"

Interactive:

reverse-api-engineer
# press Shift+Tab until the prompt shows collector
> collect companies hiring browser automation engineers

Collector mode uses the collector_model config key and writes output under:

./collected/{folder_name}/

Typical files include items.jsonl, data.json, data.csv, and README.md, depending on what the collector finds.
