How this service works
Adds a fee in basis points, to the cent.
Output
Returns the computed fee amount in USD (to the cent) derived from applying the given basis-point rate to the provided subtotal. The response allows an agent to display, log, or incorporate the fee into a total charge without performing the arithmetic locally.
Example use cases
Checkout fee display for marketplace
“The cart subtotal is $320.00 and our platform charges 50 basis points — what's the fee in dollars so I can show it as a line item before the user pays?”
Invoice line-item fee for SaaS billing
“I'm generating a monthly invoice for a client with a $1,250.00 subtotal. We apply a 30 bps processing fee — calculate the exact fee amount to the cent so I can add it to the invoice.”
Pre-trade fee estimate for DeFi agent
“Before I execute this swap, figure out what 25 basis points on a $500 subtotal comes out to in dollars so the user can confirm the fee.”
Technical details
Endpoint
POSThttps://agent-gas-station.agent-gas-station.workers.dev/v1/FeeAdd?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a server-side, authoritative basis-point fee calculation rounded to the cent — especially within an agent pipeline that handles financial amounts and cannot rely on floating-point arithmetic in the client. Prefer it over local computation when you want a consistent, auditable fee figure or when integrating with the broader Agent Gas Station toolchain for payment flows.
Side effects
- Non-numeric or missing fee_bps causes a validation error
- Non-numeric or missing subtotal_usd causes a validation error
- Negative or zero values may produce unexpected results
- Network or worker timeout if the edge function is unavailable
