How this service works
The Standard Reserve (TSR), an on-chain reserve protocol on Robinhood Chain. Today's Branch license cost in ETH, compared against the charter auction's own price to show which path costs less. 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 Branch license cost details including: basis type (license_cost), charter status and ETH price, STANDARD token price with buy tax and price impact in basis points, ETH cost estimate, branch-days equivalent, the cheapest acquisition path (charter or license), reasoning for the cheapest path recommendation, network and chain ID, the block number the estimate is based on, and any estimation assumptions (e.g. single-range constant-liquidity approximation for ETH cost).
Example use cases
Cheapest path comparison before purchase
“I'm thinking about acquiring a Branch license on The Standard Reserve — can you check the current costs for both the charter route and the STANDARD token route, and tell me which one is cheaper in ETH terms right now?”
DeFi dashboard license cost display
“Pull the latest Branch license cost from The Standard Reserve on Robinhood Chain so I can show users the current ETH price estimate and price impact on my TSR analytics dashboard.”
Automated cost monitoring for arbitrage
“Check the current TSR Branch license cost on Robinhood Chain and let me know the price in STANDARD tokens, the ETH estimate, and the price impact in basis points — I want to track this over time for arbitrage opportunities.”
Technical details
Endpoint
GEThttps://api.onesource.io/standard/v1/branches/license-cost?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a real-time, on-chain cost estimate for acquiring a TSR Branch license on Robinhood Chain, specifically when you want to compare the charter path versus the STANDARD token path with ETH cost normalization. Prefer this over manual contract reads when you need the cheapest-path recommendation logic and price impact calculations pre-computed. It is a read-only estimation endpoint with no side effects, making it safe to call frequently for monitoring or display purposes.
Side effects
- Chain RPC unavailability may return a 503 or timeout
- Stale block data if the node is behind — estimate flag will be true
- Liquidity pool has zero depth making price impact incalculable
- Payment of $0.02 USDC via x402 or MPP fails — returns 402
- Invalid or missing payment header returns 402 Payment Required
