How much does the Buffer API actually cost?
Buffer 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.
Buffer subscription pricing
| Plan | Monthly | Annual / mo |
|---|---|---|
| Free | — | — |
| Essentials | $6 | $5 |
| Team | $12 | $10 |

API at a glance
Buffer also has an MCP server
If you're wiring Buffer into Claude / Cursor / Codex, the MCP server is usually less code than the REST API.

Quickstart template
# Starter template — endpoint paths and SDK package names come from # the Buffer API docs: https://buffer.com/api curl -X GET "https://buffer.com/<your-endpoint>" \ -H "Authorization: Bearer $YOUR_API_KEY" \ -H "Accept: application/json" | jq .
Template only. Endpoint paths, exact base URL, and auth header format come from buffer.com/api.
Limits and gotchas
- No OpenAPI spec — you write typed clients by hand or use a third-party generator on the docs HTML.
- 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.
Agent-readiness verdict
Strong agent fit through a first-party MCP server. Buffer hosts an official MCP server at mcp.buffer.com with native setup docs for Claude, ChatGPT, Cursor, and Perplexity, layered on a modern GraphQL API that is now open on every plan. The gaps are real: no official OpenAPI spec or maintained SDKs, so deeper custom work leans on the GraphQL schema directly. For no-code agent posting across 11 networks, though, the MCP path is genuinely first-party.
