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"

Comprehensive search and enrichment for people, companies, investors, and jobs.

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.
• cursor (['string', 'null']) - A pagination cursor returned from a previous search response. Use this to fetch the next page of results.

curl -s -X POST $GOOSEWORKS_API_BASE/v1/proxy/orthogonal/run \
  -H "Authorization: Bearer $GOOSEWORKS_API_KEY" \
  -H "Content-Type: application/json" \

Search companies from text

Takes free-form text (e.g., 'Series A startups in USA with 50–200 employees') and returns a list of matching companies.

Parameters:

• query* (string)
• pageSize (integer) - The number of companies to return, if you need to get more results, you can paginate.
• cursor (['string', 'null']) - A pagination cursor returned from a previous search response. Use this to fetch the next page of results.

Find person by email

Do a reverse lookup: given an email address, find someone's LinkedIn profile and personal details. Note: if you also have the person's name, company, etc., you'll get better results with the Kitchen Sink endpoint, where you can pass all the information you have.

Parameters:

• email* (string) - The person's email address for which you want to do a reverse lookup
• num_profiles (['number', 'null']) - Number of profiles to return. Maximum 10 profiles can be returned for given query. The returned profiles will be sorted by best match first.

  -H "Content-Type: application/json" \
  -d '{"api":"fiber","path":"/v1/email-to-person/single","body":{"email":"john@company.com"}}'

Live fetch LinkedIn profile

Returns an enriched profile with details for a given LinkedIn profile identifier

Parameters:
