Request

curl https://api.unifapi.com/facebook/posts/comments/replies?cursor= \
  -H "Authorization: Bearer $UNIFAPI_KEY"

: The parameter for this Facebook operation. Use the URL-visible slug or id described in the docs.

Overview

This operation is part of the Facebook API in the social platforms category. It uses the same Bearer token, request tracing, error model, and billing envelope as every UnifAPI endpoint, so agents can switch between platforms without custom per-vendor glue code.

Use it when a workflow needs Facebook public data alongside other social networks, but should still keep one API key, one account balance, and one predictable JSON contract.

Common agent workflows

Pull public Facebook comment threads for sentiment, moderation, or audience-research agents.
Collect top-level discussion around a post while preserving pagination and billing metadata.
Give an AI agent a stable Facebook data source without building a per-platform integration.
Normalize Facebook responses into the same UnifAPI envelope used across the catalog.

Response shape

Unified envelope, platform-native fields

List-style responses return `data` as an array of top-level records plus optional `pagination` for continuation tokens or cursors.
The operation has a 3 credits ($0.003) minimum charge, so `billing.records_charged` can be higher than the visible records returned.
If the workspace balance cannot cover every result, the response can be truncated and `billing.truncated_due_to_balance` tells the caller why.

Billing

This operation charges 1 credit per billable record, with a 3 credits ($0.003) operation minimum. Public responses include billing metadata with credits charged, records charged, and remaining workspace balance. Incorrect Credit deductions caused by platform failures can be restored as billing corrections.

Errors and retries

Authentication, validation, rate-limit, not-found, and provider errors use the unified UnifAPI error format. Agents should log `request_id`, retry only retryable failures, and treat invalid API keys, disabled keys, and expired keys as the same public `unauthorized` error type.
