The Nexor API is lead-centric. You create and manage leads, assign them to AI agents, track their conversions, and send them messages across channels, all powered by AI agents for calls, messaging, and multi-channel outreach.

Base URL

Every request authenticates with the X-API-Key header. See Authentication for how to get and manage your key.

Quick Start

1. Get your API key

Your key lives in the Nexor dashboard under Settings, then Integrations. See Authentication for the full steps. Keys are prefixed with nxr_live_.

2. Create a lead

The lead will automatically be enrolled in the agent’s cadence sequence and start receiving AI-powered outreach.

What you can do

  • Create and manage leads. Add leads individually or in bulk, update their information, and store custom metadata.
  • Assign agents. Enroll leads into automated AI-powered outreach agents with multi-channel cadences.
  • Track conversions. Record business outcomes like reservations and closed sales with custom field metadata.
  • Send messages. Send WhatsApp messages (text or template), emails, or trigger AI phone calls to any lead.

Rate Limits

The public API is rate-limited to 100 requests per minute per API key. Requests that exceed this limit return a 429 Too Many Requests response. If you hit the limit, wait until the next minute window to retry.

OpenAPI Specification

The full OpenAPI specification is available at /openapi.json for use with API clients and code generators.
