Conventions
- Authentication:
apikeyheader on every request. See Authentication. - Content type: send
Content-Type: application/jsononPOSTandPATCH. - Timestamps: RFC 3339 / ISO 8601, UTC unless a platform says otherwise.
- Decimals: Market Data returns money and percentages as strings to preserve
precision, e.g.
"129.50". Live Availability returns numbers. - Nulls: a field that is on file but empty is
null. Fields that never apply may be omitted entirely. Treat every optional field as possibly absent. - Additive changes: new fields may appear in any response without notice. Ignore keys you do not know.
- Errors: one gateway envelope for auth, access, billing and routing; per-API formats after that. See Errors.

Each endpoint page has a playground. Paste your key into theapikey field and the
requests run against production, so paid endpoints spend real credits and
POST /watchlist creates real items.
