Get in touchImplicents & Pricing
Implicents are our usage currency for the API. Most endpoints cost 1 Implicent — 100 are included with signup.
0Implicents
Discovery
Resolve (single lookup), suggest, availability check, account info — rate-limited instead of Implicent-metered.
1Implicent
Search & profile
Search, company profile (base fields), changes, nearby, people, announcements.
2Implicents
Analytics
Peers, similar companies, person network — the embedding- and graph-based endpoints.
up to 7Implicents
Full profile
Includes stack on top of the base profile: +1 people, +1 announcements, +4 financials — everything at once is 7.
Includes on GET /v2/companies/{id} stack on top of the
base profile — each one costs its own Implicents rather than a flat bundle price:
include=people +1,
include=announcements +1,
include=financials +4 — 7 Implicents for everything at once.
Batch resolve costs 1 Implicent per 10 companies.

| GET /v2/companies/{id}/people | 1 | Standalone (1). As ?include=people on the profile: profile 1 + 1 = 2 |
| GET /v2/companies/{id}/announcements | 1 | Standalone (1). As ?include=announcements on the profile: profile 1 + 1 = 2 |
| 2 Implicents | ||
| GET /v2/companies/{id}/peers | 2 | Comparable companies |
| POST /v2/similar | 2 | Semantic match |
| GET /v2/people/{personId}/companies | 2 | Person network |
| 4 Implicents | ||
| GET /v2/companies/{id}/financials | 4 | Standalone (4). As ?include=financials on the profile: profile 1 + 4 = 5 |
| Batch | ||
| POST /v2/companies/batch/resolve | ⌈n/10⌉ | e.g. 10 companies = 1, 100 companies = 10 |
Rate limits: suggest is tuned for autocomplete bursts, resolve is throttled steadily to keep single-company loops from substituting for batch resolve.
