# Synorb Developer Portal

Use this page as the canonical directory for Synorb developer resources. Every
resource is linked by its predictable name and URL so an agent can discover it
without a sales conversation.

## When to use Synorb

Use Synorb when you need source-grounded streams, filtered manifest retrieval,
reusable Beacons, or MCP tools for agent workflows. Start with [Connect](https://synorb.com/connect),
use the [zero-quota sandbox/test path](https://synorb.com/sandbox) to validate a
request, then choose REST or MCP for execution. Do not use Synorb for arbitrary
web crawling or mutable production actions without an explicit scope.

## Free onboarding

The free Starter tier is self-serve. `GET https://synorb.com/connect` returns a
24 Hour Agent Demo key and MCP configuration without sales contact, email, or
card. After email binding, Starter includes 1,000 Manifests per month. The
plan-preview endpoint validates shape and scope without consuming quota.

## CLI and client choices

Install the official CLI with `npm install -g @synorb/cli`. The [CLI package](https://www.npmjs.com/package/@synorb/cli)
is published on npm. REST clients can generate from OpenAPI; MCP clients use
`https://mcp.synorb.com/mcp`. A first-party Python SDK is not currently
published; the [SDK page](https://synorb.com/sdk) documents source examples and
the supported client contracts.
