Fiber AI - People & Company Intelligence

Cost Reference

Cheaper alternative for people search: Apollo mixed_people/search costs $0.01 flat per call regardless of result count. Use $GOOSEWORKS_API_BASE/v1/proxy/apollo/mixed_people/search when possible.

Tip: Use the dedicated proxy route $GOOSEWORKS_API_BASE/v1/proxy/fiber/... instead of the generic orthogonal proxy for cleaner billing tracking.

Setup

Read your credentials from ~/.gooseworks/credentials.json:

export GOOSEWORKS_API_KEY=$(python3 -c "import json;print(json.load(open('$HOME/.gooseworks/credentials.json'))['api_key'])")
export GOOSEWORKS_API_BASE=$(python3 -c "import json;print(json.load(open('$HOME/.gooseworks/credentials.json')).get('api_base','https://api.gooseworks.ai'))")

If ~/.gooseworks/credentials.json does not exist, tell the user to run: npx gooseworks login

All endpoints use Bearer auth: -H "Authorization: Bearer $GOOSEWORKS_API_KEY"

Usage

Search profiles from text

Takes free-form text (e.g., 'Software engineers in US with 5+ years of experience') and returns a list of matching profiles.

Parameters:

• query* (string)
• pageSize (integer) - The number of profiles to return, if you need to get more results, you can paginate.
• getDetailedEducation (['boolean', 'null']) - Whether to include deep details about each educational item, like the school's LinkedIn URL, website, location, etc. That'll be put in the detailedEducation array. This slows down the API call, so only enable this if you need it.
• getDetailedWorkExperience (['boolean', 'null']) - Whether to include deep details about each work experience item, like the company's LinkedIn URL, website, location, etc. That'll be put in the detailedWorkExperience array. This slows down the API call, so only enable this if you need it.
