Draft: specification in progress. Endpoints and fields may change.
API usage has no monthly fee and no setup fee. TESA charges a percentage of the yield generated, the same model as the dashboard.
The fee applies only to the yield, never to the principal. A period with no yield is not charged.

​
Illustrative example

​
Partner costs

Costs charged by third parties are outside the TESA fee and follow each partner’s rules: network fees (gas) on Ethereum and Solana, any fees from the company’s custodian and management fees embedded in the USDY and BUIDL assets themselves.

​
In the API

The plan percentage appears in taxa_sobre_rendimento in GET /organizacao. The yield for each period, with the fee and the net amount, comes from GET /rendimento, and issued charges from GET /cobrancas. The cobranca.emitida event notifies you when a new charge is issued. See also Pricing.
