How this service works
The Standard Reserve (TSR), an on-chain reserve protocol on Robinhood Chain. Supply ledger history. Fields ending in _raw are 18-decimal integers as strings. Divide by 1e18 to get token amounts.
Output
An array of time-stamped supply snapshots, each containing block number, timestamp, circulating supply, cumulative minted, cumulative burned (total and split by fees/buybacks/licenses), and max supply — all in raw on-chain units — plus metadata like chain ID, lag blocks, as-of block, serving state, and the denomination basis.
Example use cases
Monitor TSR burn rate over time
“Show me the TSR token burn history on Robinhood Chain for the last 24 hours — I want to see the cumulative burned amounts broken down by fees, buybacks, and licenses.”
Audit reserve supply for compliance
“Fetch the full TSR on-chain supply ledger for the past 72 hours so I can audit how circulating supply and max supply have evolved across blocks on Robinhood Chain.”
Dashboard supply trend visualization
“Get me the block-by-block TSR circulating supply history for the last 12 hours from The Standard Reserve protocol so I can plot the supply trend on my dashboard.”
Technical details
Endpoint
GEThttps://api.onesource.io/standard/v1/supply/history?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need time-series supply data for The Standard Reserve (TSR) token on Robinhood Chain — specifically when you want historical mint/burn/circulating trends rather than a single current snapshot. Prefer this over generic blockchain RPC endpoints when you need pre-aggregated, per-block supply accounting with breakdown by burn category (fees, buybacks, licenses).
Side effects
- Invalid or missing 'hours' parameter (must be integer >= 1) returns a 400 error
- No data available for the requested time window returns an empty history array
- Chain node lag or sync issues may cause stale as-of-block data, indicated by elevated lag_blocks
- Payment failure (x402) if USDC balance is insufficient returns 402 Payment Required
- Serving state may indicate degraded mode if the underlying Robinhood Chain node is behind
