Advanced — 0.0.x primitives
You don't need this page for a normal integration. Use the quickstarts and createMythos() instead. These low-level functions remain exported for custom setups.
Configuration (Node.js)
Environment variables read by @mythos-work/sdk.
Variables
| Variable | Required | Default | Description |
|---|---|---|---|
MYTHOS_KEY | Soft in 0.5.0; required in 0.6.0 | — | Dashboard → Settings → Mythos key; binds launch, handshake and callback tokens |
MYTHOS_LISTING_ID | No* | — | Single listing ID |
MYTHOS_LISTING_IDS | No* | — | Comma-separated IDs; overrides single ID |
MYTHOS_API_URL | No | https://api.mythos.work | Mythos API base URL |
*Not required if resolveListingIds returns at least one ID.
With a key, missing or mismatched pkh rejects with ProducerMismatchError. Without a key, static listing launches remain silent; dynamic launches, handshake and callbacks warn once per process. See the shared binding contract.
