Overview
When to use Primitive
Primitive is listed for Email, Data workflows. Primitive turns email into a developer primitive. Point your MX records to Primitive and receive every inbound email as a structured JSON webhook with parsed headers, body text/HTML, attachments, and spam scoring. Works across all domains and aliases for free. Agents use it to process inbound email, extract attachments, and trigger workflows from email events. Consider it when an agent needs this capability through a documented service boundary instead of custom infrastructure maintained inside the application.
In 4agent's task model, the product maps to web extraction, user communication, workflow automation. That makes it a candidate for workflows that research the web, manage memory and knowledge, communicate with users, automate business workflows.
Integration checklist
- Access: confirm the api key authentication flow, credential scope, rotation process, and whether calls can be attributed to a user or service identity.
- Client support: official or documented clients are listed for typescript.
- Automation: OpenAPI is not currently recorded, MCP is not currently recorded, and CLI support is not currently recorded. Confirm each requirement in the provider's current documentation.
- Operations: test rate limits, timeouts, retry safety, error payloads, logs, data retention, and the current free-tier and paid pricing model with production-like volume.
