Where 1Lookup wins
- The IRS exemption record in words, with revenue, expenses, assets and liabilities for up to five years, each with its tax year, in one response
- You pay per organization listed, about $0.010 on Starter, instead of sizing a monthly request quota in advance, and a check that finds nothing is free
- A CSV with an ein column returns one row per organization, and a mistyped EIN is refused before it is charged
- The same key and balance also pay for phone, email and IP validation, and credits roll over for 3 months
Where Charity Navigator wins
- A low price per request: $25 a month for 10,000 requests is $2.50 per 1,000 and $50 for 25,000 is $2.00 per 1,000, when the quota is used.
- Ratings and alerts, not only records: more than 245,000 rated nonprofits with Charity Navigator's rating across four domains, and approximately 20,000 alerts that flag active legal, financial and ethical issues at four severity levels.
- Profile data for more than 2.4M nonprofits pulled from Form 990 or the IRS Business Master File, with name, address, EIN, causes and mission data.
- One GraphQL endpoint with a playground, and a search by term, state and rating in a single query (publicSearchFaceted).
- Every plan starts with a free 30-day trial, and Academic Use includes the first 10,000 requests a month.

Frequently asked questions
What is Charity Navigator used for?
Rating and researching US charities. Its developer API serves the research data behind charitynavigator.org: profile information for more than 2.4 million nonprofits, ratings for more than 245,000 of them and approximately 20,000 alerts, aimed at donor-advised fund platforms, giving apps, workplace giving platforms and academic research.
How does Charity Navigator API pricing work?
Monthly plans sized by a request quota, each with a free 30-day trial. Startups is $25 a month for 10,000 requests, Small is $50 for 25,000 and Midsize is $250 for 100,000, and Enterprise is custom through sales. Academic Use is pay as you go: the first 10,000 requests a month are included and each one over is $0.01. Every plan lists attribution and data sharing as required.
How much does 1Lookup charge for the same lookup?
2 credits per organization listed, free when the EIN is not listed. On the Starter plan ($99 a month for 20,000 credits) a check is about $0.010, which covers 10,000 organizations a month and is $9.90 per 1,000. At the Enterprise end of the rate card it is about $0.004. Charity Navigator's plans work out to $2.00 to $2.50 per 1,000 requests when the quota is used, so its price per request is lower than 1Lookup's on every plan.
What data comes with each Charity Navigator plan?
Startups and Small include Data Essentials queries: basic profile data and high level ratings. Midsize adds Premium queries: metrics, evaluation areas, alerts and lists. 1Lookup's lookup returns the IRS record: the exemption type in words, the category, whether donations are deductible, and revenue, expenses, assets and liabilities for up to five years from the IRS's annual extract of filed returns.
What do attribution and data sharing mean on Charity Navigator plans?
The pricing page lists 'Attribution Required? Yes' and 'Data Sharing Required? Yes' on every plan, and the developer page asks that Charity Navigator data shown anywhere follow its Attribution Guidelines. Read its terms for what data sharing involves before you build on a plan.
Does 1Lookup have ratings or alerts?
No. 1Lookup returns the IRS exemption record, a flag when the IRS marks an exemption as terminating, and the filed figures, with no rating or evaluation of the organization. Charity Navigator's ratings, evaluation areas and alerts are its own research.
Can 1Lookup search by name or by rating like Charity Navigator?
No: the lookup takes an EIN. Charity Navigator's API searches by term, state and rating in one query, so if your product lists charities for donors to browse, that part is theirs.
What is the best Charity Navigator alternative?
If you want donor-facing ratings and alerts, or a lower price per request, Charity Navigator is the better fit. If you want the IRS record with revenue, expenses, assets and liabilities by year, bulk CSV files and one balance that also pays for phone, email and IP checks, 1Lookup's Nonprofit Verify bills 2 credits only when the organization is listed.
Where does Charity Navigator beat 1Lookup?
On price per request, ratings and search. Its plans work out to $2.00 to $2.50 per 1,000 requests when the quota is used, it rates more than 245,000 nonprofits across four domains, flags approximately 20,000 active legal, financial and ethical alerts at four severity levels, searches by term, state and rating, and gives academics the first 10,000 requests a month free.
Is Charity Navigator worth it in 2026?
If your product shows donors a rating or an alert, yes: those are its own research and the price per request is low. If you only need the IRS listing and its filed figures, compare the attribution terms and the quota you would size against a price per organization listed.
