Developer API

Build with us. REST APIs, single sign-on, webhooks, and OpenAPI references.

Authenticate once, call any product

Every Evolved Sense API uses the same OpenID Connect identity server, so one access token unlocks BlogVerdict, EraEvo, SellersSense and CivilDraw APIs.

Single sign-on (OIDC)

Authority: https://identity.evolvedsense.com · Discovery: /.well-known/openid-configuration

  • Authorization-code flow for web apps
  • Device-code flow (RFC 8628) for desktop/CLI
  • Refresh tokens for long-lived sessions
  • Standard scopes: openid profile email roles offline_access

Example: get an access token

curl -X POST https://identity.evolvedsense.com/connect/token \
  -d grant_type=authorization_code \
  -d code=<code> \
  -d client_id=<your-client> \
  -d client_secret=<secret> \
  -d redirect_uri=https://yourapp.example.com/signin-oidc

Example: call an EraEvo endpoint

curl https://core.eraevo.com/api/execute \
  -H "Authorization: Bearer $TOKEN" \
  -H "Content-Type: application/json" \
  -d '{ "intent": "Build a TODO API in ASP.NET", "model": "auto" }'

Webhooks

Each product can POST events to a URL you control. Events are signed with HMAC-SHA256 using a shared secret you configure in the dashboard.

Webhook framework rolling out per-product through 2026 — see /roadmap.

Rate limits

Default: 100 req/min per access token, 1000 req/min per IP. Higher limits available on paid tiers — email [email protected].

Building With Us

Three ways to integrate

REST APIs

JSON over HTTPS, OpenAPI definitions, predictable error envelopes. Versioned with deprecation notices.

Webhooks

Subscribe to events instead of polling. HMAC-signed, retried with exponential backoff, replayable from history.

SSO embedding

Add Evolved Sense login to your own app — share users without sharing credentials.
