Symbiont API Reference

Public REST surface of Symbiont. Every endpoint returns JSON with Access-Control-Allow-Origin: *. Reads are unauthenticated. Writes that affect a subscription require the subscription_id returned by /api/subscribe.

Quickstart

curl https://forge-landing-sable.vercel.app/api/status.json

# Subscribe:
curl -X POST https://forge-landing-sable.vercel.app/api/subscribe \
  -H "Content-Type: application/json" \
  -d '{"webhook_url": "https://you.example/hook",
       "events": ["registry.new_publisher"]}'
# -> { "subscription_id": "sub_...", "credits_remaining": 100, ... }

Auth model

Reads: no auth. Everything is public.
Subscription-gated writes (/api/llm, /api/subscribe/credit): require subscription_id in body.
No API keys. No headers. No OAuth. The subscription_id is the only credential, and it's also the only thing you need to guard.
