Crustdata API
★ Only Publicly Available OpenAPI DocumentData EnrichmentCompany Databearer6 EndpointsREST
For Agents
Search and enrich company and people records, plus pull company headcount and screening data, through Crustdata's six-endpoint API.
Use for: Find companies in fintech with 50-200 employees in the US, Enrich the company stripe.com with funding and headcount data, Get the headcount history for OpenAI, Search for VPs of Engineering at Series B SaaS companies
Not supported: Does not handle CRM record creation, outbound messaging, or financial transaction execution - use for company and people search and enrichment only.
Jentic publishes the only available OpenAPI specification for Crustdata API, keeping it validated and agent-ready. Crustdata provides company and people data enrichment and search through six POST endpoints: search and enrich for companies, headcount lookup, search and enrich for people, and a combined screener for filtering companies by criteria. Authentication uses a bearer token issued by Crustdata.
Install Jentic One Beta
Connect the Crustdata API to your agent
Jentic One is a self-hosted execution layer for AI agents. It lets your agent call the Crustdata API, or any other public or private API you need. You set the rules, the agent never sees your credentials, and every call is logged.
Two steps, two machines. Install the instance in a safe environment, then register your agent from wherever it runs.

Step 1: Jentic One Host machine
# On the machine that will host your Jentic One instance:
curl -fsSL "https://jentic.com/install.sh?src=apis&api=%2Fapis%2Fcrustdata.com%2Fcrustdata" | sh2
Step 2: Agent machine
# On the machine where your agent runs (keep this separate from the instance):
curl -fsSL "https://jentic.com/install.sh?src=apis&api=%2Fapis%2Fcrustdata.com%2Fcrustdata" | sh
jentic register # connects your agent to your Jentic One instanceJentic One is in public beta. The setup above keeps your agent separate from the instance, which is what you want before using real credentials: an agent running as the same OS user as Jentic One can read its stored keys directly. Just evaluating? A single local install is fine to start. See the secure deployment guide for the tiers.
Capabilities
What an agent can do with Crustdata API.
Search companies with structured filters via POST /screener/company/search
Enrich a company record with firmographics, funding, and headcount data
Pull historical and current headcount snapshots for a target company
Search people with filters such as title, seniority, and company
Enrich a person record with contact and professional details
Run combined company screening that returns ranked results matching multiple criteria
Use Cases
Patterns agents use Crustdata API for, with concrete tasks.
★ ICP-Driven Account Discovery
Discover net-new accounts that match a defined ideal customer profile by POSTing filter criteria to /screener/screen and /screener/company/search, then enriching each result with firmographics and headcount before handing the list to outbound sales.
POST /screener/screen with industry=SaaS, employee_count_min=50, employee_count_max=200, region=US, then POST /screener/company/enrich for each result to attach firmographics.
Headcount Trend Monitoring
Watch hiring or attrition trends at target accounts by polling /screener/company/headcount on a cadence and surfacing month-over-month deltas. Useful for sales triggers ('they're hiring fast') and competitive intelligence.
POST /screener/company/headcount weekly for each target account and alert when month-over-month change exceeds 5%.
Lead Enrichment for Outbound
Take a list of leads (names plus company or LinkedIn URLs) and run them through /screener/people/enrich to attach title, seniority, and contact data. Combine with company enrichment for full account context before personalising outreach.
POST /screener/people/enrich with each lead's identifier, then POST /screener/company/enrich for the linked company to assemble a full enriched lead record.
Recruiter Talent Search
Search for candidates by title, seniority, and company filters via /screener/people/search to surface a passive talent pipeline, then enrich the best matches with /screener/people/enrich before reaching out.
POST /screener/people/search filtered by title='VP of Engineering' and company_employee_count_min=200, then enrich the top 25 results.
Agent-Driven Account Research
Allow an AI sales-research agent to answer questions like 'find ten Series B fintechs in EMEA hiring engineers' by chaining screen, search, and enrich calls through Jentic so the bearer token stays in the vault.
Search Jentic for 'find companies matching my ICP', load the screener-screen operation, and execute it with the configured filter body.

Why Jentic?
What agents get from Jentic-routed access to this vendor.
Setup
Wiring the Crustdata API by hand means setting its bearer auth and building the POST bodies for company and people search, enrichment, and headcount yourself. Through Jentic you install once, import the Crustdata API from the API Directory, store the token once, and your agent calls it.
Permission scoping
Crustdata passes its screener targets in the request body rather than the URL path, so limit the agent to the operations it needs, such as company enrichment or people search. You choose the operations it may call, so headcount or broad screener queries are not included unless you add them.
Credential isolation
Your Crustdata bearer token is stored once, encrypted, by your own Jentic One instance and injected into the Authorization header at execution time. It never enters the agent's prompt, logs, or context.
Intent-based discovery
Agents search Jentic by intent such as 'enrich a company with firmographics' or 'search for people', and Jentic returns the matching Crustdata operation with its input schema so the agent calls the right endpoint without browsing the reference docs.

FAQs
Specific to using Crustdata API through Jentic.
Why is there no official OpenAPI spec for Crustdata API?
Crustdata does not publish an OpenAPI specification. Jentic generates and maintains this spec so that AI agents and developers can call Crustdata API via structured tooling. It is validated against the live API and kept up to date. Get started with Jentic One, the self-hosted execution layer.
What authentication does the Crustdata API use?
The API uses HTTP bearer authentication. The token is issued from your Crustdata account. Through Jentic the token is held in the encrypted vault so the agent never receives its raw value.
Can I screen companies against an ICP with the Crustdata API?
Yes. POST /screener/screen accepts a multi-criteria filter body and returns ranked matching companies. Combine with POST /screener/company/enrich to attach firmographics to each result.
How do I track company headcount over time through the Crustdata API?
POST /screener/company/headcount with the company identifier returns headcount snapshots. Polling on a weekly cadence and diffing the values yields a hiring-trend signal for outbound or competitive analysis.
What are the rate limits for the Crustdata API?
The OpenAPI specification does not document numeric rate limits. Watch for HTTP 429 responses and confirm your contract limits with Crustdata support before running large enrichment batches.
How do I enrich a company through Jentic?
Run pip install jentic, search 'enrich a company with firmographics', load the company-enrich operation, and execute it with the company domain or identifier. Jentic injects the bearer token automatically.
Can I limit what my agent is allowed to do with the Crustdata API?
Yes. Because you run Jentic One yourself, you decide which Crustdata operations the agent may call, so you can grant it just company enrichment or people search while withholding the headcount and broad screener endpoints. Since Crustdata passes its screener targets in the request body rather than the URL path, scoping is done at the operation level: an operation the agent has not been given is simply unavailable to it. Your bearer token is held by your own instance and injected at execution time, so the agent can only reach the endpoints your rules permit.
