}'One API for all social media
Every platform, one request shape. Publish, schedule, and read results without learning each API.
Your language, your call
Typed SDKs for TypeScript and Python, or plain HTTP if you'd rather keep your dependency list short.
import { Configuration, PostsApi } from "@onepostly/sdk";
const posts = new PostsApi(

mediaKind: "text",
destinations: [{ connectionId: "YOUR_X_CONNECTION_ID" }],
},
});Know what happened
Every publish gets a per-platform receipt, and every failure comes back with a reason.

The hidden cost of doing it yourself
One test post is easy. Production isn't. App reviews, OAuth per account, and whatever the next platform update breaks. We absorb it so you ship features instead.
Skip App Review
Screencasts, business docs, and review cycles per platform
Skip OAuth and Tokens
Refresh handling and secure credentials for every account
Skip Media Pipelines
Chunked uploads for every format and size limit
Skip Rate Limits
Quotas, backoff, and partial failures across accounts
Skip Edge Cases
Expired tokens, scope drift, regional restrictions
Skip Silent Failures
The "why didn't this one post?" triage
Built for Agents
A hosted MCP server, curated skills, and OpenClaw support, so Claude, Cursor, and Hermes can publish and read results without a custom integration.
Integration in minutes
Ready to hand to an agent, with an llms.txt index, a full OpenAPI spec, and Markdown at every docs path.
Simple, Scalable Pricing
Free to start, fair as you scale.
Frequently asked questions
Costs, threads, scheduling, deletes, and tweet metrics, what developers ask about posting to X through Onepostly.
Still have questions?Ask our team →X usage is pay-per-use and passes through at X's own list prices with no markup, debited from a prepaid wallet you top up in Settings → Billing. Every other platform runs on your plan with no per-action fee.
Going direct means developer portal setup, OAuth flows, media rules, retries, and constant API changes to maintain yourself. Onepostly gives you one endpoint for tweets, threads, scheduling, engagement, and analytics — the same shape you use for every other platform.
Yes. Provide extra segments in the thread array and each publishes as a reply to the previous one, up to 25 segments.
Yes. Pass scheduledFor with an IANA timezone and the post goes out when that moment arrives; cancel any time before then with a single delete call. Remote delete works for published tweets and full thread chains too.
Yes. Add X alongside Instagram, LinkedIn, TikTok, and more as destinations in a single POST /v1/posts call — every destination validates independently and reports its own status.
Call GET /v1/posts/:id/insights for normalized metrics. The shares field covers retweets plus quotes, and the shape matches every other platform.
Yes. The OAuth screens your users see carry neutral names like Social Media Connector rather than our brand, so the experience reads as fully yours.
