CreatorDB has launched API Version 3, which the company describes as the fastest and most cost-efficient REST API in the creator economy, alongside an MCP server that connects creator data to consumer AI assistants. The company said the tools are already being used to build in-house influencer discovery, intelligence and analytics software.

Behind the API sits a dataset of tens of millions of influencer profiles. Each profile pulls together performance metrics, past brand sponsorships, audience breakdowns, contact emails, related socials and growth trends. Profiles are updated daily, which CreatorDB says gives users an up-to-date snapshot of potential creator partners.

On the brand side, CreatorDB tracks 15,000 brands, allowing users to see which creators each one is collaborating with. The company said teams have for years rented that kind of visibility through all-in-one platforms and worked the way those platforms allowed. Now, it argues, teams can own the tool and plug in the data, and a growing share of the industry's new software is being built in-house.

API and MCP server as a data layer

CreatorDB said AI coding tools have made in-house software realistic for almost any marketing team, and its API and MCP server supply the creator data those tools run on, starting at $79 a month.

The company described the setup as smaller than most people expect: one teammate comfortable with Claude, plus a CreatorDB API key. The output can be an influencer discovery tool, an intelligence dashboard or a performance analytics tool shaped around how a team actually works, rather than a SaaS license built around someone else's process.

CreatorDB said travel marketers have found the dataset particularly useful for visibility into each country that every travel creator has visited recently. e-SIM and VPN companies, which the company said are competing for the same pool of creators, have found the data important for building tools to detect emerging and currently underserved markets.

“The bottleneck for in-house creator tools isn't engineering anymore. It's data,” said Noah Hynam, Co-founder of CreatorDB. “We make sure you have real data from day one and at a price point that dwarfs a SaaS subscription.”

Connecting creator data to AI assistants

CreatorDB's MCP server plugs creator data into Claude, ChatGPT or any other consumer AI assistant, according to the company. Users can pull up a creator's audience breakdown or sponsorship history mid-conversation, ask why engagement dipped last month, compare the creator against others on a shortlist, or have the assistant draft a brief. The company said no code and no tab-switching are required.

CreatorDB said getting started in Claude takes a few clicks because it is listed in Anthropic's connectors directory.

What people are building with it

CreatorDB said AI-native creator economy platforms and in-house teams at brands and agencies run on its data. Examples cited by the company include:

  • AI-native creator platforms building discovery and matching products on top of CreatorDB's data.
  • Intelligence and analytics tools offering a view of influencer marketing across YouTube, TikTok and Instagram.
  • Discovery agents that take a campaign brief in plain English and return a ranked creator shortlist.
  • Vetting tools that check audience fit and past sponsorships before outreach begins.
  • Competitor sponsorship tracking showing which creators a rival brand is paying and whether those placements are working.
  • Campaign dashboards refreshed daily with how contracted creators are performing.
  • Outreach pipelines that add business contact emails to a shortlist and push it into the CRM.

Why builders pick CreatorDB

CreatorDB cited several features it says distinguish its offering.

Fractionalized profiles

Every creator profile is split into dozens of separate endpoints, so a tool can call only the data it needs. CreatorDB said this lets tools refresh fast-moving numbers such as performance metrics and new uploads daily, while checking slower data such as audience demographics, content categories or contact email once a month.

Tiered, usage-based pricing

CreatorDB uses usage-based pricing with a monthly credit allocation included in the subscription and pay-as-you-go credits beyond that. The higher the subscription tier, the lower the per-credit cost, which the company said lets a solo builder start small and grow without renegotiating a contract. At high volume, CreatorDB said a simple creator profile runs just 2 cents.

Proprietary models

CreatorDB holds 4 U.S. patents on profile data enrichment methods and has built 20 custom models that complete each creator profile. The company said those models turn raw platform signals into clean, structured fields.

No middleman

CreatorDB said it runs its own data pipeline end to end and does not call anyone else's API to serve data, which it says keeps responses quick and costs down. The company said research shows a significant number of creator economy APIs serve identical data, which it said can only result from them all using the same external data source, increasing costs and reducing maximum throughput.

Availability

The CreatorDB API and MCP server are live now. Developers can sign up at creatordb.app. Claude users can add CreatorDB from the connectors directory, and users of other providers can tell their AI to connect to CreatorDB's MCP server.
