Drive the ServiceGraph API ( https://api.servicegraph.co) to find,
shortlist, and enrich US recruiting and staffing firms via the
pro_services dataset.
This skill is for procuring an external recruiting/staffing firm to do hiring on the user's behalf. It is NOT for:
Both share keyword overlap with the positive case ("recruiter", "hire"), so the boundary matters.
Always pin industry:hr_recruiting_staffing. Sub-types
(executive search, RPO, contingent staffing, temp, vertical
specializations) are NOT separate tags — sub-type specialization is
a keyword substring search on firm text.
Any HTTP client works (curl, fetch, requests). Examples below use curl.
If your harness has the ServiceGraph MCP server loaded (tools
containing servicegraph), prefer those — OAuth 2.1 + PKCE keeps the
token in the harness sandbox. Otherwise use the REST flow below.

map) costs 10 credits per firm and lasts 30 days.
vk_* API keys minted in the dashboard. Keep the token out of the
LLM context — never read .env* into your context; dispatch via
shell.
Try the call first through a shell wrapper that sources .env.local:
bash
( set -a; [ -f .env.local ] && . ./.env.local; set +a;
curl -sS -H "Authorization: Bearer $SERVICEGRAPH_API_KEY" \
'https://api.servicegraph.co/v1/datasets/pro_services/fields' )
On 401 prompt the user:
"Open https://servicegraph.co/profile/api-keys, create a key, and add
SERVICEGRAPH_API_KEY=vk_…to.env.localhere (or export it). Tell me when done. Please don't paste the key into chat."
Retry after the user signals ready.

Four rules that bite: AND binds tighter than OR (use parens);
comma list = OR within one predicate; negation is -x or NOT x;
bareword = keyword search (quote multi-word phrases).
