Rates are non-negative decimal values. Validation is all-or-nothing: an empty asset identifier or negative rate stops the request before any rows are accepted. Accepted rows are available before the response is returned. ## OpenAPI ````yaml /risk-and-pricing/atoti-risk-services/apis-endpoints/openapi/openapi.mintlify.json post /api/MarketData/UploadAmortisationRates 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/UploadAmortisationRates: post: tags: - MarketData summary: Store amortisation rates. description: >- Use this operation to publish dated amortisation rates for service asset identifiers to a non-Derivitec provider that the caller may edit.
