Install Jentic One Beta

Connect the Charity Search API to your agent

Jentic One is a self-hosted execution layer for AI agents. It lets your agent call the Charity Search 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://raw.githubusercontent.com/jentic/jentic-one/main/tools/install.sh | sh

Step 2: Agent machine

# On the machine where your agent runs (keep this separate from the instance):
curl -fsSL https://raw.githubusercontent.com/jentic/jentic-one/main/tools/install.sh | sh
jentic register       # connects your agent to your Jentic One instance

Jentic 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.

View OpenAPI Document

Jentic publishes the only available OpenAPI specification for Charity Search API, keeping it validated and agent-ready. OrgHunter's Charity Search API exposes a directory of around 2.5 million US 501(c)(3) charities and 87,000 Canadian charities, drawn from IRS and CRA filings. The six endpoints range from lightweight name-and-EIN search through geo lookup, financial detail, and a premium endpoint with full filing data, plus a categories endpoint for IRS NTEE classifications. It is suitable for nonprofit verification, donation matching, and grant-making workflows.

Use Cases

Patterns agents use Charity Search API for, with concrete tasks.

★ Donation Matching Verification

Corporate donation-matching programs need to confirm a recipient is an active 501(c)(3) before disbursing funds. GET /charitybasic or GET /charitysearch verifies registration and returns the EIN and address, removing manual IRS lookups from the matching workflow.

GET /charitysearch?searchTerm=American+Red+Cross and confirm the matching record's deductibility status before approving the match.

Geographic Charity Discovery

Community foundations and grant-makers building local funding programs use GET /charitygeo to enumerate eligible charities within a service area. Combined with /categories filtering, the result feeds a grants pipeline scoped to a specific geography and mission area.

GET /charitygeo with a zip code and 25-mile radius, then filter by NTEE category code B for education.

Nonprofit Financial Due Diligence

Donors and watchdog projects evaluating a charity want quick access to revenue, expense, and asset figures from the most recent 990 filing. GET /charityfinancial returns those figures keyed by EIN, and GET /charitypremium adds officer detail and program descriptions for deeper analysis.

GET /charityfinancial?ein=53-0196605 and surface revenue, total expenses, and program services ratio in a donor brief.

Agent-Driven Charity Verification via Jentic

AI agents handling grant intake, donor advice, or compliance can verify charities through Jentic without provisioning the OrgHunter API key in the agent environment. Jentic exposes the six operations by intent and isolates the key.

Use Jentic to search 'verify a charity by EIN', load the GET /charitybasic schema, and execute with the EIN to return registration status.

Why Jentic?

Three things that make agents converge on Jentic-routed access.

Credential isolation

OrgHunter API keys are stored encrypted in the Jentic vault. Agents receive scoped execution access — the raw key never enters the agent's context or model prompt.

Intent-based discovery

Agents search by intent (e.g., 'verify a charity' or 'find charities near a zip code') and Jentic returns the matching OrgHunter operation with its input schema.

Time to first call

Direct OrgHunter integration: a few hours for auth and parameter handling. Through Jentic: minutes — search, load, execute.

FAQs

Specific to using Charity Search API through Jentic.

Why is there no official OpenAPI spec for Charity Search API?

OrgHunter publishes documentation but not a maintained OpenAPI document. Jentic generates and maintains this spec so that AI agents and developers can call Charity Search API via structured tooling. It is validated against the live API and kept up to date. Get started at https://app.jentic.com/sign-up.

What authentication does the Charity Search API use?

The API uses an API key passed as a query parameter (apiKey scheme). Through Jentic the key is stored encrypted in the vault and never enters the agent's context.

Can I look up a charity by EIN with the Charity Search API?

Yes. GET /charitysearch and GET /charitybasic both accept an EIN parameter and return the matching charity record including registration status.

What are the rate limits for the Charity Search API?

The OpenAPI spec does not declare numeric rate limits. OrgHunter throttles requests by plan tier — confirm the per-minute cap on charityapi.orghunter.com before running large enrichment batches.

Is the Charity Search API free?

OrgHunter offers a free tier for basic search and tiered paid plans for premium endpoints like /charitypremium and /charityfinancial. Pricing and rate caps are listed on charityapi.orghunter.com.

How do I find charities within a geographic radius through Jentic?

Search Jentic for 'find charities near a zip code', load the GET /charitygeo schema, and execute with the zip code and radius in miles.
