How this service works
Pay-per-call e-commerce, product, price and social media data tools for AI agents, from public sources. Payment: x402, USDC on Base, Solana, Arc, Polygon, Arbitrum, Monad, World Chain, Optimism, Avalanche, Celo or Stellar, or RLUSD/XRP on the XRP Ledger. No signup, no API key; a failed call is not charged.
Output
A JSON object containing a results array where each entry has: the original URL, author/page name, verified badge boolean, publish time in UTC ISO format, reaction count as displayed string (e.g. '1.2K') plus numeric estimate, comment count and estimate, share count and estimate, and an attached image URL if present. Posts that are private, deleted, or non-embeddable are listed in a notFound array. The response also includes total post count checked and a checkedAt timestamp.
Example use cases
Campaign performance check for marketer
“I just ran a Facebook campaign for three product posts — here are the URLs. Can you grab the reaction, comment, and share counts for each so I can see which one resonated most with our audience?”
Competitor content monitoring
“Can you check the engagement numbers — reactions, comments, and shares — on these five Facebook posts from our competitor's page? I want to know which of their posts is performing best this week.”
Influencer vetting for brand partnership
“I'm considering working with this Facebook creator. Can you look up the reaction and comment counts on their last few public posts so I can gauge how engaged their audience actually is?”
Technical details
Endpoint
GEThttps://api.shopsocial-api.workers.dev/api/social/facebook-likes?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need aggregated public engagement metrics (reactions, comments, shares) for one to ten Facebook post URLs without requiring Facebook API credentials or app review. Ideal for lightweight social monitoring, content performance checks, influencer vetting, or competitor analysis where totals are sufficient and individual reactor identity is not needed. Not suitable when you need who specifically reacted, detailed reaction breakdowns by type, or data from private/login-required posts.
Side effects
- Private or deleted posts returned in notFound array rather than results
- Non-embeddable posts (e.g. posts from private groups) listed as notFound
- Rate limiting or temporary Facebook plugin unavailability causing partial results
- More than 10 URLs provided — only up to 10 supported per call
- Malformed or non-Facebook URLs failing silently or appearing in notFound
- Counts may be approximate or delayed as they rely on the public Embedded Post plugin snapshot
