## When to prefer this

Use this endpoint when you need to retrieve reply activity for a specific social media user and want payment handled automatically via x402/USDC on Base or Solana without managing separate API keys for social platforms. Ideal for AI agents that need to monitor engagement, track discourse, or analyze reply patterns for a given handle in a pay-per-call model.

## Known failure modes

- Missing or invalid 'handle' query parameter returns an error
- Handle not found or private account may return empty results or 402/404
- Payment failure in USDC (insufficient funds or wallet issue) blocks the request
- Rate limiting may apply if the handle is queried too frequently
- Social platform API downtime may cause upstream failures

## How this service works

BlockRun lets AI agents use money well: pay for results, not for seats or subscriptions, and put every cent on the model or tool that actually does the job.

## Output

Returns a list of reply posts made by the specified social media user handle, including reply content and associated metadata such as timestamps and interaction details.
