What is the Publer API?

The Publer API is a public REST interface to posts, schedules, engagement metrics, and mentions. Auth is handled with api_key. Official SDKs cover node, which keeps boilerplate to a minimum. An OpenAPI spec is published, which means you can auto-generate typed clients from it.

Typical builds: cross-channel scheduling pipelines fed from a Notion content calendar, real-time mention monitoring with sentiment scoring, and weekly engagement reports auto-generated from raw post data.

For agent workflows specifically, the community MCP server is usually less code than the REST API. The API still wins for scheduled jobs, dashboards, and anything outside an LLM-driven flow.

How much does the Publer API actually cost?

Verify on docs

Publer publishes an API, but per-tier gating wasn't extracted automatically.

  • Most likely scenario: API access is either included in all paid plans, or it's gated to higher tiers and we need to verify on the live docs page.
  • Until verified, treat the question "which plan unlocks the API" as open. Don't budget on the assumption it's free with the cheapest paid plan.

Publer also has an MCP server

If you're wiring Publer into Claude / Cursor / Codex, the MCP server is usually less code than the REST API.

What you can build with the Publer API

Three personas, three different shapes of build. Pick the row that matches how you actually ship.

SOLO DEV / FOUNDER

Glue Publer into your daily workflow

  • Pull a digest of fresh activity into your morning Slack
  • Trigger a one-off backfill when something looks off
  • Pipe data into your own SQLite for ad-hoc queries
Effort: A weekend, one Node or Python script
AGENCY / CONSULTANT

Sell Publer reporting at scale

  • White-label Publer data into client-branded dashboards
  • Run scheduled multi-account reports without logging into the Publer UI
  • Cross-reference with the rest of the client's stack (CRM, analytics, ad spend)
Effort: 1-2 weeks, hits multi-tenant auth quickly
IN-HOUSE ENGINEER

Production pipelines for Publer

  • Real-time sync into your warehouse on a cron
  • Custom alerts the dashboard's built-in alerting can't express
  • Backfill + idempotency handling for Publer data older than the dashboard exposes
Effort: Multi-week project, expect rate-limit tuning

Quickstart template

# Starter template — endpoint paths and SDK package names come from
# the Publer API docs: https://publer.com/docs

curl -X GET "https://publer.com/<your-endpoint>" \
  -H "Authorization: Bearer $TOKEN" \
  -H "Accept: application/json" | jq .

Template only. Endpoint paths, exact base URL, and auth header format come from publer.com/docs.

Limits and gotchas

  • OpenAPI is published — auto-generated clients work out of the box. Saves writing wrappers by hand.
  • Official SDKs: node. Use them to skip auth boilerplate and get type safety.
  • Rate limits: always read the docs page before scaling — the published limit is usually lower than the practical one and overages can be expensive.
5/10

Agent-readiness verdict

Middling agent fit, with a real API but a community MCP. Publer documents an official REST API (bulk scheduling, analytics) but gates it to Business and Enterprise plans, so cheaper tiers get no programmatic access. MCP support comes from a low-traction community server (alexkess/publer-mcp-server) wrapping that API, not a first-party endpoint, and there are no official SDKs or OpenAPI spec. It is automatable across 13 networks if you are on a Business plan and comfortable with a community bridge.
