device auth
Canonicalizes device_id, nonce and message, computes an HMAC-SHA256 tag with caller-supplied ephemeral key material, and optionally compares a claimed tag in constant time. It does not provision devices, store keys or replace asymmetric device identity; do not submit long-lived production secrets.

edge compute bid
POSThttps://iot.halowerk.com/v1/edge-compute-bidFilters caller-supplied bids by CPU, memory and latency constraints, computes workload cost from quoted unit prices, and ranks feasible candidates by total cost then latency. It does not contact providers, attest hardware or place a bid.
