# GCIS, free, GET /od/data/api/4347A009-6489-4F19-AC79-78F366BE7976: Company discovery API

> 提供「統一編號」與「公司名稱」清單

GCIS's company discovery API on its Free plan. It costs $0.00 per 1,000 companies. It returns none of the 13 key fields we check: Description, Industry, Type and status, Images and 9 more.
GCIS limits how many pages you get but gives no number.
We haven't run GCIS through [our company discovery API benchmark](https://datacircle.dev/best-company-discovery-api.txt) yet.
Half of the 771 plans we rank by price cost $1.00 per 1,000 companies or less. This plan and 56 others tie for the lowest price per 1,000 companies of the 771 plans.
[PeopleSearch.im's $5 pack](https://datacircle.dev/company-discovery-apis/peoplesearch-im/5-pack/llms.txt) covers any number of companies. PeopleSearch.im's $5 pack costs less up front than StackScan's $189 monthly plan.
[GetProspect](https://datacircle.dev/company-discovery-apis/getprospect/49-monthly/llms.txt), [Hunter](https://datacircle.dev/company-discovery-apis/hunter/49-monthly-starter-post-discover/llms.txt) and [PeopleSearch.im](https://datacircle.dev/company-discovery-apis/peoplesearch-im/5-pack/llms.txt) are the best company discovery API providers in the Datacircle benchmark.
