Mock packet
Wire the response shape without using live market-state capacity.
Five-minute integration
Get from packet shape to first live loop without reading the whole API map.
Engineers can wire deterministic mock packets before payment, then swap the same route shape to live latest, Workbench, replay, feedback, and usage after API-plan key issuance. The goal is one useful packet loop, not the full API map on day one.
Latest packet
After checkout, call live latest with the x-market-state-api-key header.
Workbench
Open evidence, replay context, row joins, routes, and feedback handles.
Usage receipt
Review cost and capacity before expanding symbols or replay depth.
curl "https://api.etnaalpha.io/api/public/market-state/mock/latest?symbol=BTCUSD-PERP"const base = "https://api.etnaalpha.io/api/public/market-state";
const headers = { "x-market-state-api-key": process.env.ETNA_API_KEY };
const latest = await fetch(`${base}/latest?symbol=BTCUSD-PERP`, { headers })
.then((response) => response.json());
const workbench = await fetch(
`${base}/packets/${latest.rows[0].event_id}/workbench`,
{ headers },
).then((response) => response.json());Best first system path
Pro is the default when the integration needs repeated context.
Builder is enough to verify BTC and ETH. Pro is the first active workflow for dashboards, agents, alerts, and internal monitors that need five approved symbols and repeatable packet review.
Before key
Wire the mock route
Use deterministic mock packets to test schema and route handling.
Recommended
Start Pro loop
Five approved symbols, live packets, replay, Workbench, webhooks, and usage receipts.
