Use whenever the user wants to find, shortlist, vet, or enrich US accounting and tax firms (CPA firms) — financial-statement audit, SOC 1/2 audit, corporate tax, bookkeeping for businesses, advisory/fractional CFO, M&A diligence, 409A valuations, R&D tax credits, IPO readiness, sales-and-use tax. Triggers on "find me a CPA firm for our delaware c-corp series A audit", "shortlist three audit firms with SaaS experience", "we need a tax advisor for our M&A", or "pull contact info for these 10 accounting firm domains", even when described indirectly (audit our books, fractional CFO support, file our 1120).

Drive the ServiceGraph API (https://api.servicegraph.co) to find,
shortlist, and enrich US business-to-business accounting and tax
firms (CPA firms) via the pro_services dataset.
The catalog is B2B-only. Personal tax prep (individual 1040s,
retirement planning, individual estate planning, personal bookkeeping
for freelancers) is out of scope — those firms were filtered during
the catalog audit.
Always pin industry:accounting_tax. Sub-services (audit, tax,
bookkeeping, advisory, M&A diligence, 409A, R&D credits, etc.) are
NOT separate tags — industry:accounting_tax is the most specific
structured level — so practice-area specialization is a keyword
substring search on firm text.
Any HTTP client works (curl, fetch, requests). Examples below use curl.
When NOT to use this skill
Personal/individual tax matters: 1040 prep, IRA/Roth conversions, personal estate planning, "what should I do with my refund".
Bookkeeping for a freelancer or solo creator's personal income.
the ServiceGraph MCP server (https://mcp.servicegraph.co) loaded in
your harness — this plugin's .mcp.json wires it up; OAuth 2.1 + PKCE
keeps credentials in the harness sandbox — or
a ServiceGraph API key (vk_…, minted at
https://servicegraph.co/profile/api-keys) available as
SERVICEGRAPH_API_KEY in the environment or .env.local for the REST
path (setup steps under Auth below).
An HTTP client for the REST path — the examples use curl.
Instructions
The loop is free-first: discovery, validation, search, and brief reads cost
nothing; only unlock after the user confirms the spend.
Pick the call path — the ServiceGraph MCP tools if loaded, otherwise the
REST flow (MCP server and Auth sections below).
GET /v1/datasets/pro_services/fields?include_values=1 — confirm the
fields and values you plan to filter on exist.
Build the filter (Filter DSL below) and validate it with
GET /v1/datasets/pro_services/check — or draft it from plain English via
POST /v1/datasets/pro_services/translate-intent.
GET /v1/datasets/pro_services/search — present the free brief cards and
let the user pick.
Quote the unlock cost (10 credits per row, 30-day TTL) and get an explicit
go-ahead.
POST /v1/datasets/pro_services/unlocks with the chosen apexes; report the
revealed detail.
GET /v1/me/credits to report the remaining balance when asked.
MCP server (preferred for authed calls)
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.
API surface (dataset id: pro_services)
Every endpoint requires the bearer (Authorization: Bearer vk_…).
No anonymous tier.

GET /v1/datasets/pro_services/:apex

{apexes:[...]} ≤100; atomic; 30-day TTL on detail.
GET /v1/me/credits
free
Balance.
Cost model. Discovery / validation / search / brief reads are
free. Detail (url, phone, email, social, address, full platforms
map) costs 10 credits per firm and lasts 30 days.
Auth
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:
"Open https://servicegraph.co/profile/api-keys, create a
key, and add SERVICEGRAPH_API_KEY=vk_… to .env.local here
(or export it). Tell me when done. Please don't paste the key
into chat."
Retry after the user signals ready.
Filter DSL
GitHub-search-style.
filter := orExpr
orExpr := andExpr ("OR" andExpr)*
andExpr := notExpr (("AND")? notExpr)* # whitespace = implicit AND
notExpr := ("NOT" | "-") notExpr | atom
atom := "(" filter ")" | predicate
predicate:= IDENT op valueOrList | bareword
op := ":" | "=" | ">=" | "<=" | ">" | "<"
valueOrList := value ("," value)*
value := IDENT | NUMBER | tagAtEvidence
tagAtEvidence := IDENT "@" ("low"|"medium"|"high")
bareword := IDENT | NUMBER # → keyword:<bareword>
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).
Accounting-flavored examples (validate yours with /check):
Firms are identified by their apex domain (pwc.com, not
www.pwc.com/about).
Output
All responses are JSON.
Search returns free brief firm cards — apex, name, location, and
rating signals — plus a per-row unlock hint and the match total. Briefs
never include url, phone_primary, email_primary, legal_name,
address_full, or the full platforms map.
Unlock (POST …/unlocks) returns each unlocked firm's detail block —
contact fields, address, socials, the platforms map — plus per-item
billing; detail stays readable for 30 days.
Errors arrive as a JSON envelope
{"error": {"code": "…", "message": "…"}} — see Errors below.
Examples
A. CPA firm for a Delaware C-corp audit
User: "CPA firm for our delaware c-corp series A audit, under 50 ppl."
GET /v1/datasets/pro_services/search?filter=industry:accounting_tax+audit+state:DE,NY,CA+-company_size_signal:large_50plus&limit=10
# Present, get pick of 3. "Unlocking 3 = 30 credits, 30-day TTL."
POST /v1/datasets/pro_services/unlocks
{ "apexes": ["firm-a.com", "firm-b.com", "firm-c.com"] }
B. SaaS-experienced audit firms
GET /v1/datasets/pro_services/search?filter=industry:accounting_tax+audit+saas&limit=10
C. M&A diligence
User: "Tax advisor for our M&A — Series-B-stage tech company."
GET /v1/datasets/pro_services/search?filter=industry:accounting_tax+"m&a"+diligence+tech&limit=10
D. Fractional CFO (indirect intent)
User: "Fractional CFO to help us through a Series-A close."
GET /v1/datasets/pro_services/search?filter=industry:accounting_tax+"fractional cfo"&limit=10
If thin, drop the cfo qualifier — fractional alone catches
fractional finance leaders broadly.
E. R&D tax credits
User: "R&D tax credit specialists for biotech."
GET /v1/datasets/pro_services/search?filter=industry:accounting_tax+"r&d"+biotech&limit=10
F. Multi-state DTC sales tax
User: "Outside accountant for state and local tax filings — multi-state DTC business."
GET /v1/datasets/pro_services/search?filter=industry:accounting_tax+("sales tax" OR salt)+multi-state&limit=10
If barely any results, drop multi-state and surface the dimension
from the unlocked detail later.
G. BYO apex list — enrich domains
User pastes 8–20 accounting-firm domains:
GET /v1/datasets/pro_services/:apex per domain — free brief
(404 = not in catalog, no charge).
User picks N to fully enrich. POST /unlocks = 10×N credits,
atomic, detail returned.
Re-runs within 30-day TTL are free.
A 404 here often means the firm focuses on personal tax prep and was
filtered out of the B2B catalog.
Gotchas
Always pin industry:accounting_tax. Without it, "tax" / "audit" / "cfo" as keywords match management consulting and other industries.
Refuse personal-tax asks. 1040 prep, IRA conversion strategy, personal estate planning, "should I use QuickBooks Self-Employed?" — not in catalog. Tell the user the catalog is B2B-only.
industry:accounting_tax is the only structured handle. Practice areas (audit, tax, M&A, 409A, R&D credits) are keyword-only. Multi-word areas split into ANDed barewords unless quoted ("r&d tax credits" → one phrase).
In-house finance hires (Controller, CFO, Accountant) are NOT procurement. Recruiting an employee is out of scope.
Accounting-software comparisons (QuickBooks vs Xero vs NetSuite) are NOT procurement either.
Briefs DO include apex, name, location, ratings. They DON'T include url, phone_primary, email_primary, legal_name, address_full, full platforms — those require an unlock.
not_found / not_in_dataset 404 = not in pro_services. Skip; not charged.
Unlock is atomic. N apexes either all charge (up to 10×N credits) or none on 402.
