The Influencer Marketing Tool Built for Developers

Find influencers by niche, country, and follower count. Get business emails instantly. $0.10/search, no subscription. API + MCP for AI agents.

The Problem

Finding influencers for marketing campaigns is manual, expensive, and locked behind $299/month platforms designed for marketing teams — not developers or AI agents.

How Developers Actually Need Influencer Data

You need an API that returns structured JSON with emails, follower counts, and engagement metrics. Not a dashboard with drag-and-drop campaign builders.

How Social Intel Works

One API call. Send a category, country, and follower range. Get back up to 100 influencer profiles with public business emails. Pay $0.10 per search in USDC — no signup, no API keys.

Real Results from the API

Sample profiles from the Social Intel API — the same data format you get from the search endpoint.

curl "https://socialintel.dev/v1/search?category=Fitness&limit=10"

# Returns 402 Payment Required with price info
# Pay $0.10 in USDC → get JSON results instantly

# Or use the MCP server:
# npx -y social-intel-mcp

How Influencer Marketing Tools Compare by Price

The influencer marketing tool market spans a wide range of price points, from free marketplace models to enterprise platforms costing thousands per month. Your choice depends on how you work: do you need a dashboard with campaign management, or do you need raw data you can plug into your own workflow?

Reading the Table: What the Price Tiers Mean

Dashboard tools like Modash and HypeAuditor bundle discovery, analytics, and campaign management into a single monthly subscription. You get a browser-based interface, team collaboration features, and often some form of outreach automation. The trade-off is cost: even at the lowest tier, you are committing to $199+ per month whether you run one search or one thousand.

Enterprise platforms like Upfluence and GRIN typically require annual contracts and custom pricing. They add features like e-commerce integration (pulling purchase data from Shopify to match with influencer-driven sales), content rights management, and multi-market campaign coordination. These platforms target brands spending $50,000 or more per year on influencer partnerships.

Marketplace tools like Collabstr and Ainfluencer take a different approach entirely. Instead of charging brands for search access, they act as two-sided marketplaces where creators list their services and brands browse or post briefs. The trade-off: smaller databases, less filter granularity, and less control over outreach.

API tools like Social Intel sit in a category of their own. There is no dashboard, no campaign manager, and no team seats. You get a REST endpoint that returns structured JSON — influencer profiles with usernames, follower counts, bios, categories, and public business emails. You pay $0.10 per search and integrate the data into whatever workflow you already use. For developers building their own tools, agencies with existing CRMs, or AI agents that need machine-readable data, this is the most cost-efficient option by a significant margin.

Cost Comparison: 100 Searches Per Month

To make the pricing concrete, here is what 100 influencer discovery searches per month costs across these tools:

• Social Intel API: $10.00 (100 searches x $0.10)
• Modash: $199.00 (monthly subscription, regardless of search volume)
• HypeAuditor: $299.00 (monthly subscription)
• Upfluence: $800+ (estimated, requires annual contract)
• GRIN: $2,200+ (estimated, annual contract)
• Collabstr: $0 for browsing, but limited filtering and no bulk export

At low to moderate search volumes, pay-per-search pricing is 20-200x cheaper than subscription platforms. The breakeven point — where a subscription becomes cheaper — is roughly 2,000 to 3,000 searches per month, which is well beyond what most teams need.

What to Look for in an Influencer Marketing Tool

Not all influencer marketing tools are created equal, and the features that matter most depend on your workflow. Here is a checklist of the factors that should drive your decision, ranked by how frequently they separate a good tool from a mediocre one.

Database Size and Freshness

The total number of profiles in a tool's database matters less than you think. HypeAuditor claims 137 million profiles. Modash claims 250 million. Social Intel has 33 million with a focus on accounts that have public business emails. In practice, most searches return results from the same pool of active, mid-tier creators. What actually matters is data freshness — how recently the profiles were updated. An influencer who had 500,000 followers six months ago may have 800,000 today, or may have gone inactive. Tools that update their data weekly or daily give you more reliable results than those running quarterly refreshes.

Filter Granularity

The power of any influencer discovery tool lives in its filters. At minimum, you need:

• Niche or category: Fitness, Travel, Beauty, Food, Technology, etc. The more granular the category taxonomy, the better your results.
• Country and city: Essential for local campaigns and geo-targeted partnerships. Some tools only support country-level filtering; Social Intel supports both country and city.
• Follower range: Filter by minimum and maximum followers to target nano-influencers (1K-10K), micro-influencers (10K-100K), mid-tier (100K-1M), or macro-influencers (1M+).
• Gender: Important for brands with gendered products or campaigns targeting specific demographics.
• Engagement rate: Some platforms calculate engagement rate (likes + comments / followers). Useful but often unreliable due to algorithm changes and engagement pod manipulation.
• Verified status: Filter for or against verified accounts depending on your campaign goals.

Contact Data

This is the most overlooked differentiator. Many influencer tools will show you profiles but not provide contact information. You end up sending Instagram DMs that get lost in request folders, or manually searching for email addresses on personal websites. A tool that returns public business emails as part of its search results saves hours of manual research and dramatically improves outreach response rates. Business emails listed on Instagram profiles are there because the creator wants brand inquiries — they convert 3-5x better than cold DMs.

Pricing Model

Consider how your usage patterns align with the tool's pricing model:

• Per-search pricing (Social Intel): best for variable or low-volume usage. You pay only when you search.
• Monthly subscription (Modash, HypeAuditor): best for teams with steady, high-volume search needs. Fixed cost regardless of usage.
• Annual contract (Upfluence, GRIN, CreatorIQ): best for enterprise teams with predictable budgets. Lowest per-unit cost, but high commitment and difficult to cancel.
• Commission-based (Ainfluencer): no upfront cost, but the platform takes a percentage of each deal. Best for one-off collaborations.

API Access

If you are a developer or run any kind of automated workflow, API access is non-negotiable. Many dashboard platforms either do not offer an API at all, or charge extra for it on top of already expensive subscriptions. Social Intel is API-first — every feature is accessible via a single REST endpoint. This matters for building custom dashboards, integrating influencer data into CRMs, or connecting discovery to automated outreach sequences.

AI Agent Compatibility

In 2026, AI agents are increasingly handling marketing workflows autonomously — from identifying target influencers to drafting and sending outreach emails. For this to work, your influencer tool needs to be machine-accessible. Two protocols are emerging as standards:

• MCP (Model Context Protocol): Allows AI agents like Claude, GPT, and custom LLM agents to discover and call tools directly. Social Intel ships an MCP server (npx -y social-intel-mcp) that gives any MCP-compatible agent access to influencer search.
• x402 (HTTP 402 payments): Enables AI agents to pay for API calls autonomously using USDC stablecoin. No API keys, no OAuth, no human in the loop. The agent receives a 402 Payment Required response, pays the specified amount, and gets the data.

If you are building or deploying AI agents for marketing automation, these capabilities matter more than any dashboard feature. Most traditional influencer marketing tools have no AI agent integration at all — they require a human operating a browser.
