Drive the ServiceGraph API ( https://api.servicegraph.co) to find and
rank directories where a founder can submit a software product — SaaS
review sites (Capterra, G2, SaaSHub), launch platforms (Product Hunt and its
alternatives), app/startup listings, and general software directories — via
the product_directory dataset. The catalog has 1,000+ directories, each
enriched with Domain Rating ( dr), backlink counts, and organic
traffic, so you can rank by real SEO value and reach instead of guessing.
This is a "where to launch / where to get backlinks" skill, not a "who to hire" skill. Each row is a directory you submit to, not a firm and not a product. The payoff for the user is twofold: a backlink from a high-authority domain (SEO) and launch-day referral traffic.
Any HTTP client works (curl, fetch, requests). Examples below use curl.
If the user's product is specifically one of these, defer to the dedicated skill (its catalog slice and recipes are tuned for it):
find-mcp-directoriesfind-ai-directoriesThis skill is the umbrella for everything else founders launch — SaaS, web apps, mobile apps, dev tools, startups in general — and is the right pick when the ask spans niches or names none.
If your harness has the ServiceGraph MCP server loaded (recognizable by tool
names containing servicegraph), prefer those tools — the harness handles
credentials in its own sandbox via OAuth 2.1 + PKCE, so no token enters LLM
context. Otherwise use the REST flow below.
product_directory)#Every endpoint requires the bearer ( Authorization: Bearer vk_…). There is
no anonymous tier.

Cost model. Discovery / validation / search / brief reads are free —
including the dr ranking signal. Unlocking a row costs 10 credits and
lasts 30 days; it reveals the gated fields: editor_note (the
hand-written submission note — how to submit and whether the listing gives
a backlink), organic_traffic, and total_visits. Re-fetching an unlocked
row within TTL is free.
Tokens are vk_* API keys minted in the dashboard.
Keep the token out of the LLM context — never read .env* into your
context; dispatch every authed call through a shell wrapper.
Just try the call 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/product_directory/fields' )
On 401 unauthorized, prompt the user (don't accept the key in chat):
"Open https://servicegraph.co/profile/api-keys, sign in, click Create key, and copy the
vk_…value. Then addSERVICEGRAPH_API_KEY=vk_…to.env.localhere (or export it in your shell). Tell me when done. Please don't paste the key into chat."
Retry the same call after the user signals ready. A later 401 means the key was rotated/revoked — re-prompt.
GitHub-search-style.

Four rules that bite:
a OR b c parses as a OR (b AND c). Use parens.industry:software_saas,fintech = either.-x or NOT x. Use saas -crm, not keyword:saas,-crm.niche
tag (so saas matches dirs whose niche is "SaaS products"). Multiple
barewords AND. Wrap multi-word phrases in double quotes ( "product launch").This dataset ranks directories by SEO value and reach, so the numeric signals are the point:

Because dr is free and briefs are pre-sorted by it, you can rank a
shortlist by authority without spending a single credit — unlock only the
ones the user wants submission instructions for.
apex#Directories are keyed by apex domain ( producthunt.com, not
www.producthunt.com/posts). Strip user-supplied URLs to the apex before
calling :apex endpoints or building unlock batches.

organic_traffic is gated but filterable — gate on it to surface
high-reach dirs, then unlock to see the numbers:

GET /v1/datasets/product_directory/search?filter=saas+organic_traffic>=50000&limit=15
# → small set of high-traffic dirs. Unlock the user's picks to reveal traffic + how to submit.
User: "Directories for our fintech app." / "design-tool listing sites."
Combine a keyword (matched against the niche tag) with the industry
refiner, or just lead with the keyword:
text
GET /v1/datasets/product_directory/search?filter=fintech&limit=15
GET /v1/datasets/product_directory/search?filter=design+dr>=50&limit=15
If a keyword over-narrows, drop it and use industry: (e.g.
industry:software_saas, industry:fintech) plus dr>=.

User has a shortlist and wants to actually submit:
text
# Present briefs ranked by dr (free). "Unlocking 6 = 60 credits, 30-day TTL —
# this reveals each one's submission note (how to submit, backlink yes/no) and traffic."
POST /v1/datasets/product_directory/unlocks
{ "apexes": ["producthunt.com", "saashub.com", "uneed.best", "..."] }
# → editor_note + organic_traffic + total_visits for each.
The editor_note is the operational payoff — e.g. "Listing doesn't give a
backlink but seeds several other directories; submit via CLI, see …". Surface
it verbatim so the user knows the effort and the SEO return before submitting.
User pastes a list of directory domains:
