No API Available

Option 4: Clay (Manual Enrichment)

Best for: building a custom creator list from LinkedIn or Twitter data.

1. Create a Clay table with columns: creator_name, platform, handle, follower_count, topic, post_frequency, avg_engagement
2. Use clay-claygent to research each creator: "Find the LinkedIn follower count, posting frequency, and average engagement for [handle]"
3. Use clay-enrichment-waterfall to enrich with email addresses for outreach
4. Score creators using a Clay formula column (see creator-outreach-pipeline drill)

Error Handling

• Rate limits: SparkToro and Modash both rate-limit API calls. Implement exponential backoff. Modash returns 429 Too Many Requests with a Retry-After header.
• No results: If searches return zero creators, broaden the topic keywords or increase the follower range. B2B micro-influencers are often categorized under general "business" or "tech" rather than niche terms.
• Stale data: Creator metrics change. Re-run discovery monthly to catch new creators and drop inactive ones.
