How this service works
The Standard Reserve (TSR), an on-chain reserve protocol on Robinhood Chain. How the reserve's exit fee changes across a range of withdrawal sizes, checked two ways: a live contract read and this service's own formula. Fields ending in _raw are 18-decimal integers as strings. Divide by 1e18 to get token amounts.
Output
Returns a JSON object with the current exit fee rate as a WAD-scaled integer (both live and formula-derived), the fee ladder showing fee amounts and marginal fees at each gross tier, the gross amount used (raw and in units), the block the data was read from, the Robinhood Chain network ID (4663), and the formula version string.
Example use cases
Pre-redemption fee check for TSR
“Before I redeem my STANDARD tokens from The Standard Reserve, can you pull the current exit fee curve and tell me what rate I'd pay on a gross redemption of 1000 STANDARD tokens?”
Monitor TSR exit fee trend
“Check the live exit fee rate on The Standard Reserve right now and tell me what the formula version is and which block it was computed from — I want to track whether fees are rising.”
Evaluate TSR redemption cost for DeFi arbitrage
“I'm comparing exit costs across reserve protocols. Can you get the full fee ladder from The Standard Reserve exit fee curve, including marginal fees and fraction-of-gross breakdowns for each tier?”
Technical details
Endpoint
GEThttps://api.onesource.io/standard/v1/exit/fee-curve?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need the current exit fee rate or fee ladder for The Standard Reserve (TSR) on Robinhood Chain (chain ID 4663), particularly before executing a STANDARD token redemption. Prefer this over raw eth_call approaches when you want pre-parsed fee curve data including WAD-scaled rates, marginal fees, and tiered ladder breakdowns without writing contract ABI logic. Best for agents performing redemption cost analysis, exit pressure monitoring, or DeFi arbitrage calculations involving TSR.
Side effects
- Invalid 'gross' query parameter type (non-integer or negative) returns a 400 validation error
- Network or RPC connectivity issues to Robinhood Chain return a 503 or timeout
- Payment not included or insufficient for x402 pay-per-call mode returns a 402 Payment Required
- Block data temporarily unavailable during chain reorganization may return stale or error response
