search1api-cli

Command-line interface for Search1API — web search, news, crawl, sitemap, trending, and turning a URL into an Agent Skill, from your terminal.

Installation

Quick install (no Node.js required)

curl -fsSL https://cli.search1api.com/install.sh | bash

This downloads a standalone binary and installs it as s1.

Via npm

npm install -g search1api-cli

This installs two commands: search1api and s1 (shorthand).

Updating

s1 update

s1 update updates you in place using whichever method you installed with:

• Binary install — downloads the latest release for your platform and replaces the running binary (uses sudo automatically if needed).
• npm install — prints the npm install -g search1api-cli command to run.

s1 also checks for new versions in the background and shows a notice when one is available.

Setup

Authorize the CLI with OAuth 2.1 in your browser. The CLI dynamically registers as a public client, uses Authorization Code with PKCE, and refreshes access tokens automatically:

s1 login

Manual fallback:

s1 config set-key <your-api-key>

Or use an environment variable:

export SEARCH1API_KEY=<your-api-key>

Commands

crawl

Extract content from a URL.

sitemap

Get related links from a website.

s1 sitemap https://example.com

learn

Turn a URL into an installable Agent Skill directory.

s1 learn https://example.com/guide --name example-setup       # one page
s1 learn https://example.com/docs --site --discover           # what would be learned, crawls nothing
s1 learn https://example.com/docs --site --name example-api   # crawl and stage
s1 learn https://example.com/docs --site --exclude /docs/cloud --name example-api
s1 learn --from <staged dir> --install project                # install, no crawl
s1 learn --from <staged dir> --install global --name better-name   # install under a new name
s1 learn --refresh ~/.agents/skills/example-api                # relearn, same source and scope
s1 learn --validate ~/.agents/skills/example-api              # static checks, exit 1 on errors

<name>/
  SKILL.md                 # routing layer: when to use, what is in references/
  references/*.md          # page content with title/url frontmatter
  references/sources.json  # source URLs, hashes, and any pages that failed

Option	Description	Default
--name <name>	Required. You choose it; the CLI never derives one
--site	Learn everything under the URL's path, not just that page	off
--discover	With --site: print the section breakdown and stop	off
--exclude <paths...>	Path prefixes to leave out
--max-pages <N>	Safety valve, not a knob to tune	500
--out <dir>	Where to write the directory	staging dir under the cache
--from <dir>	Install an already-learned directory instead of crawling
--refresh <dir>	Relearn using the source, mode and --exclude it recorded
--validate <dir>	Report problems in a learned directory
--install <scope>	global (~/.agents/skills/) or project (./.agents/skills/)	not installed
--json	Output raw JSON

--site reads the site's published sitemap in one call and keeps what lives under the URL you pointed at — the docs root gets everything, /docs/api gets just that section — so the page count comes from the site rather than from a budget you have to guess. --discover shows that breakdown first.

One run produces one skill, and one bundle per documentation set is the default. Point at a single section only when that section is plainly its own job; before crawling you only have URLs, and grouping pages by their slugs guesses wrong on the pages that matter.

Nothing is installed unless --install is passed, and a directory s1 learn did not create is never overwritten. Relearning the same URL rewrites references/, reports what changed, and keeps a SKILL.md you have edited.

Installing writes the skill to the store (~/.agents/skills/<name>) and links it into the agent directories that already exist beside it — .claude/skills, .cursor/skills, .codex/skills — because agents read their own directory, not the store. The output names every link it made, and says so when it found none:

$ s1 learn --from ~/.cache/search1api/learn/example-api --install global
example-api installed to /Users/you/.agents/skills/example-api
Linked into /Users/you/.claude/skills/example-api, /Users/you/.codex/skills/example-api

It never creates a directory for a tool you have not set up, and never replaces an entry that is already there.

A freshly learned skill is not usable yet. s1 learn writes a placeholder description, and an agent will not select a skill that still carries it — the command says so when it finishes, and --validate fails with a non-zero exit:

$ s1 learn --validate ~/.agents/skills/example-api
error  SKILL.md still has the generated description, so this skill will not trigger.

Rewrite the description to name the topics the skill answers, and turn the generated page list into a routing table, before calling it done.

--name on install renames the folder, the frontmatter and sources.json together, so you can learn under a working name and settle on the real one after reading what the pages actually contain.

--exclude drops whole path prefixes, but a section is not automatically one thing: umami's /docs/guides holds 21 hosting guides and 11 core how-tos. Point --discover at a section before excluding it.

Page content is written straight to disk. The command prints a summary, and --json lists only file, url, and title per page — so learning a large site does not push its text through the agent that ran it.

SDK

Plugin and integration packages can reuse the CLI's authentication, OAuth refresh, request handling, and typed Search1API methods instead of maintaining a second client:

import { search, crawl } from "search1api-cli/sdk";

const results = await search("OpenCode plugins", {
  maxResults: 5,
  searchService: "github",
});

const page = await crawl("https://example.com");

The SDK uses SEARCH1API_KEY, the shared s1 login OAuth session, or the optional per-call apiKey. Every method also accepts an AbortSignal so host applications can cancel tool calls.

Agent skill and plugins

This repo is the distribution point for the Search1API Agent Skill, which drives the s1 CLI. The Claude and Codex plugins, OpenCode, OpenClaw, and Grok Build plugins reuse the same Search1API SDK, hosted MCP server, and research workflow from their own repositories.

Once installed, you can ask the host agent things like:

• "search for the latest AI news"
• "what does this link say? https://example.com"
• "what's trending on GitHub?"
• "research quantum computing thoroughly"
• "learn these docs so you can use them later"

Agent Skill

Install the standalone skill:

npx skills add superagents-lab/search1api-cli

Claude

Search1API is listed in the Claude directory as a connector: claude.ai/directory/connectors/search1api. Add it from Customize > Connectors in claude.ai; it also works in Claude Code. The Claude plugin, which pairs the connector with a research skill, is maintained in search1api-mcp/claude-plugin.

To use the s1 CLI from Claude Code instead, install the standalone skill with npx skills add superagents-lab/search1api-cli.

Codex

The Codex plugin pairs the hosted MCP server with a research skill and is maintained in search1api-mcp/codex-plugin:

codex plugin marketplace add superagents-lab/search1api-mcp
codex plugin add search1api@superagents-lab

To use the s1 CLI from Codex instead, install the standalone skill with npx skills add superagents-lab/search1api-cli.

Grok Build

Install the dedicated grok-search1api plugin directly from GitHub:

agent plugin install superagents-lab/grok-search1api --trust

The same repository can also be added as a custom Grok marketplace:

agent plugin marketplace add superagents-lab/grok-search1api

OpenCode and OpenClaw

Install the dedicated OpenCode plugin from npm:

opencode plugin opencode-search1api

Install the dedicated OpenClaw plugin from ClawHub:

openclaw plugins install clawhub:@fatwang2/openclaw-search1api

See the source repositories for platform-specific configuration and release details:

• opencode-search1api
• openclaw-search1api
• grok-search1api

MCP

The hosted MCP server and its directory listings live in search1api-mcp. It is also published as io.github.superagents-lab/search1api in the official MCP Registry.

JSON Output

All commands support --json flag to output raw JSON, useful for piping and scripting:

s1 search "test" --json | jq '.results[0].title'
s1 balance --json
