For Agents

Validate a U.S. nonprofit's IRS status and OFAC sanctions exposure by EIN and retrieve a date-stamped due-diligence PDF.

Install Jentic One Beta

Connect the CharityCheck to your agent

Jentic One is a self-hosted execution layer for AI agents. It lets your agent call the CharityCheck, 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 CharityCheck, keeping it validated and agent-ready. Candid CharityCheck validates the nonprofit status and eligibility of a single U.S. organisation by EIN against IRS Publication 78, the IRS Business Master File, the Internal Revenue Bulletin, the Automatic Revocation of Exemption list, and the OFAC Specially Designated Nationals list. Two GET endpoints accept an EIN (optionally scoped by state) and return organisation type, deductibility limitations, religious-organisation status, revocation history, and a date-stamped Charity Check PDF for due-diligence archiving.

Use Cases

Patterns agents use CharityCheck API for, with concrete tasks.

★ Grant-Making Due Diligence

Foundations and donor-advised funds must verify a recipient's tax-exempt status and sanctions exposure before disbursing a grant. CharityCheck returns the IRS Publication 78 record, BMF data, and OFAC SDN status for a given EIN in one call, with a downloadable PDF that auditors can keep on file as evidence of compliance.

GET /v1/{ein} for the grantee's EIN, confirm status='Subsection 501(c)(3)' and revoked=false, then archive the returned PDF reference in the grant record.

Donation Platform Eligibility Filtering

Donation platforms need to refuse contributions to revoked or sanctioned charities at submission time. Calling CharityCheck before charging the donor surfaces revocation, deductibility, and OFAC matches so the platform can block the transaction or warn the donor that their gift may not be tax-deductible.

GET /v1/{state}/{ein} when the donor selects a charity, refuse the donation if revoked=true or any OFAC match is reported.

Corporate Matching Gift Workflows

Employer matching-gift programs validate that nominated charities are eligible 501(c)(3) public charities before approving a match. CharityCheck returns the organisation type and deductibility limit, letting HR systems auto-approve eligible charities and route ineligible nominations for manual review.

GET /v1/{ein} for the employee's nominated charity and approve the match only when organisation_type='Public Charity'.

AI Agent Charity Compliance via Jentic

Through Jentic, an agent searches for 'verify a U.S. charity by EIN', loads the input schema for /v1/{ein}, and executes the call without managing the Subscription-Key header. Jentic's vault holds the Candid subscription key so it never enters the agent's prompt context.

Use the Jentic SDK to search 'verify a U.S. charity by EIN', load the /v1/{ein} operation schema, and execute it with the EIN to confirm 501(c)(3) status and OFAC clearance.

Why Jentic?

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

Credential isolation

The Candid Subscription-Key is stored encrypted in the Jentic vault. Agents receive scoped execution rights and Jentic injects the key into the Subscription-Key header at call time, so the raw key never enters the agent's context.

Intent-based discovery

Agents search by intent (for example, 'verify a U.S. charity by EIN') and Jentic returns the matching CharityCheck operation along with its input schema, so the agent can call /v1/{ein} without browsing developer.candid.org.

Time to first call

Direct CharityCheck integration: half a day for header configuration and PDF link archival. Through Jentic: under 30 minutes to search, load, and execute.

FAQs

Specific to using CharityCheck API through Jentic.

Why is there no official OpenAPI spec for CharityCheck?

Candid documents CharityCheck through its developer portal but does not publish a redistributable OpenAPI specification. Jentic generates and maintains this spec so that AI agents and developers can call CharityCheck 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 CharityCheck use?

It uses an API key passed as Subscription-Key, either in the request header or as a query parameter. Through Jentic, the key is stored in the Jentic vault and injected into the Subscription-Key header at execution time, so the raw key never enters the agent's prompt context.

Can I retrieve a downloadable PDF for archiving?

Yes. The CharityCheck response references a date and time-stamped Charity Check PDF that grant-makers and auditors can archive as evidence of due-diligence at the moment of validation. The Charity Check PDF API is included with the same subscription key.

How do I look up an EIN through Jentic?

Run pip install jentic, then search 'verify a U.S. charity by EIN' through the Jentic SDK. Jentic returns GET /v1/{ein} with its input schema. Provide the 9-digit EIN and execute the operation; supply the state code as well to use /v1/{state}/{ein} when state context is known.

Are CharityCheck records updated as IRS data changes?

Yes. Candid refreshes CharityCheck against the IRS Publication 78, Business Master File, Internal Revenue Bulletin, and Automatic Revocation feeds, so a request returns the latest status visible to Candid at the time of the call. The PDF carries the timestamp of the lookup.

Is CharityCheck free?

No. CharityCheck is a paid Candid product accessed via subscription. Pricing details are not in the OpenAPI spec; check developer.candid.org for current tier prices and call quotas.
