Official Late API reference for scheduling posts across 13 social media platforms.

  • Building with the Late Social Media Scheduling API
  • SKILL.md covers Quick Start, Rule Files and Supported Platforms
  • Calls curl; reaches getlate.dev
  • Tasks that involve Webhooks

What it does

Late API is an agent skill from sundial-org/awesome-openclaw-skills. Official Late API reference for scheduling posts across 13 social media platforms. Covers authentication, endpoints, webhooks, and platform-specific features. Use when building with the Late Social Media Scheduling API.

Its SKILL.md is about 580 tokens, which your agent loads only when the skill is triggered. The skill folder holds 14 other files (for example `README.md`, `rules/accounts.md` and `rules/analytics.md`).

It sits in Backend & APIs, covering Webhooks. The repository describes itself as: Top OpenClaw skills, with the most popular and useful ones.

When your agent uses it

  • Building with the Late Social Media Scheduling API
  • Tasks that involve Webhooks

Example prompts

  • “/late-api”

Requirements

  • A credential in YOUR_API_KEY

What it can do on your machine

Read from SKILL.md and the folder at commit b80cde2. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • curl

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Hosts in commands or code, which the agent is likely to contact:

    • getlate.dev

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Late API loads about 580 tokens when it runs. Until then it costs about 57 tokens; SKILL.md has 133 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~57
When it runs · the whole SKILL.md, loaded when a task matches
~580

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

SKILL.md

Without a licence we can't republish the file, so here is its outline and opening line. It has 133 words (~580 tokens).

“Schedule posts across 13 social media platforms with a single API.”
