Changelog

Material changes to the API: new endpoints, parameters, response fields, deprecations, and breaking-change notices. Cosmetic dashboard updates and internal performance work are not logged here.

Versioning policy

The current API version is v1. We commit to keeping the v1 contract backward-compatible for the foreseeable future:

Additive changes (new endpoints, new optional parameters, new response fields) ship without notice. Your code should ignore unknown fields and tolerate new endpoints appearing.
Behavior changes that could affect output (e.g. tighter validation, calculation refinements) ship with at least 14 days' email notice and a tag here.
Deprecations (a field or endpoint planned for removal) ship with at least 90 days' email notice and a tag here. The deprecated thing keeps working through the deprecation window.
Breaking changes (removed fields, renamed endpoints, schema redesigns) only happen on a new major version (/api/v2/). The previous major stays online for at least 180 days after the new one launches.

Reference docs corrected to match live responses

FIXED

Updated the Reference examples so documented field names match exactly what the API returns. No API behavior changed — docs only. Corrected:

/radar: top-level dollar gamma is net_gamma (not net_gex); per-strike data is the levels array with strike / gamma / call_gamma / put_gamma / oi_call / oi_put; documented spot_source, spot_updated_at, gamma_flip_type, available_dte_modes.
/history: container is snapshots (not rows); each entry uses timestamp (not ts) and net_gamma; top-level minutes + count.
/heatmap: returned as a sparse cells array of {strike, expiry, gex} (not a 2-D matrix); added date.

If you parse live response shapes directly, your existing keys are unchanged — this only brings the docs in line with reality.

v1.0 — Initial release

ADDED

The first public release of the GEXBoard API. Available endpoints at launch:

GET /api/v1/radar — live GEX snapshot per ticker (Net GEX, walls, flip, regime, per-strike contributions)
GET /api/v1/spot — cached spot price (public, no auth)
GET /api/v1/history — rolling history of GEX snapshots, tier-gated lookback
GET /api/v1/heatmap — strike × expiry GEX matrix (Pro+)
GET /api/v1/greeks — per-strike DEX, Vanna, Charm, Vomma (Trader)
GET /api/v1/premium-map — premium concentration by strike (Trader)
GET /api/v1/volume — live 0DTE per-contract volume (Pro+, requires active session)

Two tiers at launch: Pro API ($89/mo add-on, 60 req/min, 50,000 req/day) and Trader API ($169/mo add-on, 300 req/min, unlimited daily). Both require an active Pro or Trader base subscription.
