API Overview

Base URL

All API requests use the following base URL:

https://api.agentscore.com

Authentication

Every request must include an API key in the X-API-Key header:

curl -H "X-API-Key: as_live_your_key_here" \
  https://api.agentscore.com/v1/credentials

Get your API key from the dashboard. Requests without a valid API key receive:

{
  "error": {
    "code": "signup_required",
    "message": "Sign up for a free account to use the AgentScore API.",
    "signup_url": "https://www.agentscore.com/sign-up"
  }
}

Tiers

See pricing for current tier names, quotas, and rate-limit numbers. Endpoint availability shown below by paid vs. free; tier names in this table reflect the live pricing page.

POST /v1/sessions	Yes	Yes	Yes
GET /v1/sessions/:token	Yes	Yes	Yes
