Which creator marketing platforms have an API you can build on in 2026?

Creator platform APIs are separated by two independent questions. The first is capability: does the API only return information, such as creator profiles, audience data and posts, or can it also take campaign actions, such as setting up a campaign or sending an invite? The second is the caller: does a team's own code call a conventional API, or does an AI assistant call it through MCP? A conventional API can take actions too, and an MCP connector can be read-only, so check each question on its own.

A creator data API costs five figures a year at the published entry point, and it is often a separate contract from the platform seat. Modash's API page, read on November 2, 2026, lists the Discovery API from $16,200 per year and the Raw API from $10,000 per year, on a monthly credit system, covering 380M+ creator profiles across Instagram, TikTok and YouTube. The same page answers whether a platform plan includes the API with “No, the Modash platform & API are priced separately.”

Ask three questions of any data API before signing: how often profiles are refreshed, how credits are counted per call, and whether the data may be stored in your own systems after the contract ends. The answers decide the real cost more than the list price does.

Creator platforms are adding MCP connectors because marketers increasingly work inside AI assistants, and MCP lets one connector reach several of them. Anthropic introduced the protocol on November 25, 2024:

For a brand team the protocol is a question of who does the work, not of what the API can do. Influencer Marketing Hub's 2026 Benchmark Report (published May 4, 2026) found 66.33% of respondents run influencer marketing entirely in-house. A team that does not want to write and maintain code can work through a connector in plain language inside its assistant; a team with engineers can build on a conventional API.

Before building on a creator platform API, check what it can do, what it costs per call, and what stops it from acting on its own. Those three answers separate an API a team can rely on from one that becomes a maintenance job.

1. Read or write? Can it only return data, or can it also set up campaigns and send messages?
2. Approval on writes. Does every action that sends or spends wait for a person's confirmation?
3. Sign-in. Does it use the team's own accounts and permissions, or a shared key?
4. Pricing. Is it part of the platform plan or a separate contract, and how are calls metered?
5. Data freshness. How old can a creator profile be when it comes back?

Storika fits teams that want to run creator campaigns from their own AI assistant, and its connector both reads and takes actions. With Storika's MCP connector at https://api.storika.ai/mcp, a team can find creators and set up campaigns from Claude, ChatGPT, Cursor or Grok, signing in with its own Storika account. The connector finds creators across sources with one ask, sets up the brand and its campaigns, sends TikTok Shop invites and messages, and messages creators on Meta Creator Marketplace.

Nothing sends without your yes. For TikTok Shop invites and DMs, Meta Creator Marketplace messages and campaign enrollment, the first call returns a proposal and changes nothing; the step runs only after the marketer confirms it. Setup steps for each assistant are in Storika's connector docs.
