Each curve identifies an equity and value date and supplies positive day maturities or valid tenor strings, together with either positive discount factors or annualised decimal rates. `UseZeroRates` selects zero rates; otherwise rates are forward rates. Invalid curves are reported while other valid curves can be stored, and an accepted curve replaces the contribution for the same provider, equity, and value date before the response returns. ## OpenAPI ````yaml /risk-and-pricing/atoti-risk-services/apis-endpoints/openapi/openapi.mintlify.json post /api/MarketData/UploadBorrowCurves openapi: 3.0.4 info: title: Derivitec Api 1.0 version: '1.0' servers: - url: https://api.riskportal.activeviam.com security: - oauth2: [] - apikey: [] tags: - name: AdminUser - name: AtotiReport - name: AtotiSession - name: BloombergOAuth - name: Bond - name: BondYieldCurvePage - name: BookAccess - name: Books - name: Commodity - name: Counterparties - name: Currencies - name: Equity - name: EquityDividend - name: EquityPage - name: FeatureFlag - name: Fx - name: FxPage - name: GroupAccess - name: Home - name: LegacyPosition - name: MarketData - name: MarketDataProvider - name: MarketDataProviderAccess - name: Meta - name: Notification - name: Organisation - name: PnLReport - name: PortfolioAccess - name: Portfolios - name: Position - name: PositionFilter - name: PricingEnvironment - name: PricingEnvironmentAccess - name: RateAsset - name: RateAssetPage - name: Report - name: ReportDefinition - name: ReportHistoryLauncherQuery - name: ReportLauncher - name: ReportQuery - name: ReportQueryViewUser - name: ReportRestriction - name: ReportView - name: RiskReport - name: Tradable - name: TradeBooking - name: User - name: VarReport - name: VarReportQuery - name: YieldCurvePage paths: /api/MarketData/UploadBorrowCurves: post: tags: - MarketData summary: Store borrow curves for equities. description: >- Use this operation to publish borrow curves to a non-default provider that the caller may edit.
