The free tier should answer one question quickly: can this workflow reach the right venue family, route shape, auth pattern, and response envelope before paid volume is needed? The free path is for a fit check. It should answer whether 0xArchive supports the venue family, symbol shape, route, response envelope, and first workflow you need. It should not be presented as unlimited production capacity, raw redistribution permission, or a replacement for plan-specific terms.Documentation Index

What To Confirm First
| Check | Why it matters | Page |
|---|---|---|
| API key works | Confirms auth and response envelope | Quickstart |
| Venue family is correct | Prevents core, Spot, HIP-3, HIP-4, and Lighter mixups | Venue Coverage |
| Symbol is supported | Prevents category-based assumptions | Data Availability |
| Freshness is acceptable | Prevents stale data entering downstream jobs | Data Quality |
| Limits are understood | Prevents unbounded scripts and retry loops | Rate Limits |
| Use rights fit | Prevents confusing internal API use with redistribution | Data Rights |
Starter Workflow
Create a key
Use the dashboard key flow and keep the key in an environment variable or secret store.
Choose the real route family
Move from the quickstart example to the route family your actual job needs.

Upgrade Signals
You are ready to evaluate a paid plan when the workflow needs longer windows, more symbols, higher request volume, concurrent queries, replay, L3/L4 depth, Data Catalog exports, production support, or explicit commercial terms. Do not wait until a generated script is already hammering the API. Size the job first, then choose the plan.Boundary
The free tier does not make unsupported venue data available. It does not grant rights to resell or redistribute raw data. It does not remove the need to check freshness. It is a starting lane for a real integration, not the operating model for a production market-data stack.Starter Packet
Use the free tier to fill a small starter packet before any broad workflow runs.| Field | Starter check |
|---|---|
| Key path | Dashboard key stored outside source control |
| Route family | One supported venue family and one exact symbol |
| First response | Envelope shape, status code, and request ID |
| Freshness | Data-quality check for the same family and symbol |
| Limit posture | One bounded request before loops, replays, exports, or agent-generated jobs |
| Rights posture | Internal evaluation only unless terms say otherwise |
