The superagnt Facebook API wraps Facebook surface areas into a single integration. Instead of managing multiple keys, proxies, and rate limits yourself, you call superagnt with one credential and consume structured JSON optimized for downstream AI and analytics. Whether you are building a social listening agent, a content research pipeline, or a creator-intelligence product, this API gives you consistent access to page and group posts, marketplace listings, video content, and ad discovery with predictable billing and operational simplicity.
If this client speaks MCP, you can connect the Facebook Data facet server instead of using this skill's curl calls — the same endpoints below as native MCP tools with structured parameters and OAuth sign-in, scoped to this capability:
text
https://mcp.superagnt.com/mcp/facebook
That URL publishes full OAuth discovery: an MCP-capable client needs the URL
and nothing else (approve once in the browser). On clients that hold a bearer
instead, add it as an Authorization: Bearer header. Per-client setup lines:
https://mcp.superagnt.com/agent-setup/prompt.md
This skill document stays fully usable on curl-only environments — everything below works with just the API key.
Get an API key from the dashboard and export it as
SUPERAGNT_API_KEY. Every request sends it as a Bearer token:
text
Authorization: Bearer $SUPERAGNT_API_KEY
If the variable is not set, ask the user for their key or point them at https://superagnt.com/r/ch-facebook-data-key.
One call proves the key, the credit balance, and this source end to end:
bash
curl -s https://api.superagnt.com/v1/credits \
-H 'Authorization: Bearer $SUPERAGNT_API_KEY'
A JSON result means you are live. A 401 means the key is wrong or missing; a 402 means the workspace is out of credits — the dashboard shows both.

This skill covers Facebook Data only — the endpoints listed above,
nothing else. The same API key also works with superagnt's other data sources
and platform tools, but those are separate listings that the user installs or
enables themselves; this skill does not add or enable anything beyond what is
documented here. The public catalog is at https://api.superagnt.com/v1/platforms.
