5 Best APIs for Provider Credentialing in 2026

Looking for the best API for provider credentialing?

Physicians fill out around 18 credentialing applications a year, according to a 2023 Health Affairs Scholar study. So it's no wonder more teams want credentialing to run from the systems they already use, like their ATS or onboarding flow.

But "credentialing API" can mean two very different products, and the one you pick decides how much work stays with your team. We'll get into both in a second, right after a quick word about us.

Why Listen to Us?

The National Committee for Quality Assurance (NCQA) certifies us in all 11 of its evaluation products as a credentials verification organization (CVO). Our platform delivers committee-ready files in under 48 hours. Birches Health, for example, grew from 10 providers in 2 states to 800 across all 50 states with us. Along the way, they saw processing speeds up to 75% faster per credential.

We run that same work through our own API, so we know what your team needs from one.

What Is a Provider Credentialing API?

A provider credentialing API connects your software to a credentialing service. Your system sends a provider's details over, and verified results come back automatically. The checks behind those results are called primary source verification (PSV). That means confirming each credential with the issuing authority, like the state board that granted a license.

For example, when you hire a psychiatrist licensed in New York and New Jersey, your ATS can send their details to the API. The API then checks both licenses with the state boards. It also confirms their DEA registration and runs them against federal exclusion lists. And nobody on your team has to log into a single website.

What you get back depends on the kind of API. A verification-data API returns each result on its own, so your team still builds the file for your credentialing committee. A credentialing-workflow API is run by a CVO, and it hands you the committee-ready file itself. Either way, payer enrollment comes afterward as its own step, and that's what sets the provider up to bill insurance plans.

5 Best Provider Credentialing APIs

Before we get into each one, the table below shows what each API hands back and where it stands with NCQA. NCQA lists these vendors under two separate programs, CVO Certification and Credentialing Certification, so we've named the program next to each status.

1. Assured

Assured is an AI-powered platform that automates provider credentialing, licensing, and payer enrollment for healthcare organizations. Our API lets your engineers connect that work to the tools you already use, like your ATS, EMR, or onboarding flow. You send a provider in and get a committee-ready file back, without anyone on your team chasing a state board. You'll find the details in our public API reference.

In practice, your system starts by creating the provider in Assured or importing their profile from CAQH (now DataSpring). CAQH is where providers keep their self-reported credentialing details. Then you open a credentialing request for the states you need, and our AI agents run primary source verification across 2,000+ sources. You can follow each request through the API and download the finished file when it's ready. But the credentialing decision itself stays with your committee.

Key Features

Through the API, your system can:

• CAQH import: Pull in a provider's CAQH profile so nobody has to retype it.
• Progress tracking: See which checks are pending and whether a verifier has signed off.
• REST API: Create or import providers, initiate credentialing requests, and retrieve provider information, credentialing statuses, verification results, and completed packets through Assured's API.

Meanwhile, our AI agents and platform do the credentialing work itself:

• Monitoring schedule: We query the NPDB daily and check OIG, SAM, and state exclusion lists monthly.
• NCQA timing checks: We flag any verification that falls outside NCQA's time limits before it reaches your committee.
• Automatic recredentialing: Recredentialing kicks off automatically before each provider's three-year deadline.
• Parallel verification: AI agents run primary-source verifications across 2,000+ sources at once, so large files don't wait on one check after another.
• Committee-ready packets: The platform assembles verified files into standardized packets in under 48 hours. It records each result's source, timestamp, and outcome for audits.
• Ongoing monitoring: We track licenses, sanctions, exclusions, and expirations continuously and flag sanctions within 24 hours. That way, you'll know about a lapse before it affects billing.

Pros

• Your engineers can read every endpoint in our public API reference before writing any code.
• Every verification records its source, timestamp, result, and evidence for your auditors.
• Payer enrollment has its own endpoints in the same API, so you can add it later.

Cons

• You may need our team's help with integration credentials and setup, so plan for that step.

2. Verifiable

Verifiable is a provider credentialing and monitoring platform with a public REST API, which is the standard style most web software uses. For each credentialing request, you can send it to Verifiable's own NCQA-certified CVO or run the workflow yourself. And when you add a supported license type, Verifiable checks it with the licensing source automatically.

Key Features

• Credentialing packets: Have Verifiable's CVO build the packet when you'd rather not assemble it in-house.
• Dataset scans: Run OIG, SAM, NPDB, DEA, OFAC, and specialty-board checks through one scan endpoint, with one dataset per request.
• Bulk monitoring: Monitor sanctions for up to 100 providers at once.
• Event alerts: Get a message in your system when something changes, like a license expiring.

Pros

• Its default limit of 10,000 requests every 5 minutes can handle big roster loads.
• NCQA lists its Credentialing Certification in 11 products.
• You can credential facilities with the same request you use for individual providers.

Cons

• Server-to-server sign-in (OAuth) and single sign-on are premium add-ons.
• You have to go through support to get staging and production access.
• Its docs don't list an SDK, so you'll either generate a code library from the spec or call the API directly.

3. ProviderTrust

ProviderTrust's API needs just a provider's NPI to start, and it returns license, DEA, board certification, and exclusion data from primary sources. ProviderTrust describes its DynamicNPI data as "not a full-service CVO," so your own team still builds the file and runs the committee review.

Key Features

• Instant NPI search: Check one NPI against exclusions, opt-outs, licenses, and OFAC in one call.
• One-time verification: Verify a provider once without enrolling them in monitoring.
• Source screenshots: Pull the source page screenshot for a license or board action.
• Sandbox: Test in a separate sandbox once ProviderTrust grants access.

Pros

• NCQA lists its Credentialing Certification in 9 elements, including licensure, DEA, and board certification.
• One connection covers one-time checks and ongoing monitoring.
• You can start monitoring a provider with nothing but their NPI.

Cons

• Its public docs don't cover committee review, file assembly, or payer enrollment.
• According to its docs, new profile requests take up to 7 days on average.
• Some paid-source checks, like American Osteopathic Association lookups, must be started manually.

4. Propelus

Propelus Data Solutions is an API for license verification, exclusion screening, and ongoing monitoring that runs underneath your own credentialing workflow. Keep in mind that its results expire after 7 days, so you'll want to save them on your side.

Key Features

• License results: Get each license's status, expiration date, a disciplinary-action flag, and a screenshot link.
• Batch checks: Send up to 100 licenses at a time for one-time verification.
• AdverseCheck screening: Screen people against OIG, GSA SAM, OFAC, TRICARE, and state Medicaid lists.
• Continuous monitoring: Keep an eye on licenses and exclusion status without rerunning checks.

Pros

• NCQA lists it as CVO-certified in 7 elements, including licensure, DEA, and board certification.
• It screens organizations as well as individual people.
• It has a separate demo environment, so you can test before going live.

Cons

• Its public docs don't cover credentialing files, committee review, work history, or NPDB checks.
• You have to email Propelus support to get API credentials. Rate limits depend on your plan, from 10 requests per second on Basic to 50 on Enterprise.
• We didn't find an OpenAPI file for its current API, so your engineers will work from the written docs.

5. Baton Health

Baton Health is a primary source verification data API used by credentialing teams, payer operations, and telehealth companies. It's built on GraphQL, a query style that lets your engineers ask for exactly the fields they need. Baton sends back verification data and PDFs, and your own team builds the rest of the file.

Key Features

• License search: Look up licenses by NPI, license number, or state, and see each one's status, expiration, and board actions.
• Roster monitoring: Add a provider and license pair to a roster so Baton keeps monitoring it.
• Verification PDFs: Generate a point-in-time verification with a downloadable PDF.
• Delivery options: Get the data via API, scheduled flat files, or an MCP server for AI assistants.

Pros

• Baton connects to hundreds of primary sources across all 50 states.
• Roster operations are free, so you only pay when you search or verify.
• You can take the data as flat files if you'd rather not build against the API.

Cons

• It isn't NCQA-certified yet. As of late October 2026, NCQA still lists its Credentialing Certification as scheduled rather than granted.
• It returns data and PDFs, so your team still assembles the committee-ready file.
• Rate limits cap you at 3 requests per second and 100 per minute. For big roster loads, you'll need to ask Baton for more.

How we evaluated these APIs

We started with the question that matters most when you're choosing an API. How much credentialing work will it actually take off your hands?

For each option, we read the vendor's public API and product docs, plus NCQA's certification information where available. Then we compared them on four points:

• Access and integration: Are the docs public? How do you get API credentials? Can you test before going live?
• What comes back: Are you getting separate data points, verification evidence, or a complete file for committee review?
• NCQA status: Is the organization certified, and for which verification categories?
• Monitoring: Can it help you catch license, sanctions, or exclusion changes after initial credentialing?

This comparison covers published capabilities only, and we didn't run any hands-on performance benchmarks. So before you buy, check pricing, source coverage, access terms, and certification status directly with the vendor.

How to choose a provider credentialing API

First, decide how much of the credentialing process you want the API to take on.

Some APIs give you individual verification results, like license statuses, exclusions, and board certifications. Others run the verification process for you and return a completed file for committee review. If your team already has a credentialing workflow in place, the first kind might be all you need. But if you're trying to cut down on manual work, you'll probably want the second.

Once you've settled that, it's worth checking these too:

• NCQA certification: Check which verification categories the vendor is certified for, since certification may not cover every service it offers.
• Source coverage: Make sure the API supports the states, licensing boards, and other primary sources your providers need.
• Ongoing monitoring: Find out whether the API checks for license expirations, exclusions, and sanctions after the initial verification.
• Integration: Read the API docs and check the authentication requirements, rate limits, and whether you can test before you commit.
• Pricing: Ask about per-verification fees, monitoring costs, minimum commitments, and charges for accessing certain sources.

Finally, ask to see a sample API response or completed credentialing file. It'll tell you more about how useful the integration will be than a feature list ever could.

Choose the API that fits the work your team wants to do

All five options can help you get credentialing information into your systems. They mostly differ in how much your team still has to do once that information arrives.

If you're happy with your credentialing process and just need better source data, a verification API may be exactly what you need. If you want to go from provider intake to a committee-ready file without putting it together by hand, book a demo with Assured. We'll walk you through how the API fits into the provider onboarding process you already have.

FAQs

1. How often does a provider need to be credentialed?

NCQA requires recredentialing every three years, so each provider must complete primary source verification at least every 36 months. That's why an API that tracks each provider's next recredentialing date helps.

2. What is the difference between provider enrollment and credentialing?

Credentialing verifies a provider's qualifications, such as their license, training, and work history, with the primary source. It ends with a committee-ready file. Provider enrollment, also called payer enrollment, comes after that and registers the credentialed provider with insurance plans so they can bill. Our guide to credentialing vs. payer enrollment walks through both in more detail.

3. Should you use a credentialing API or file-based submissions?

Use an API if your ATS, EMR, or onboarding flow sends each new hire as they arrive and needs results back right away. File-based submissions, like a roster sent over SFTP, work better for big periodic updates. And plenty of teams use both.

4. How much does credentialing software cost?

None of the five APIs in this guide publish their rates, so expect to get a quote through a demo. When you do, ask how pricing scales with your provider count and whether any sources carry pass-through fees. Our pricing is usage-based, so it grows with your volume.
