How this service works
The Standard Reserve (TSR), an on-chain reserve protocol on Robinhood Chain. Per-day history for the license or charter Dutch auction: open price, floor, close price, and how much sold each day. Fields ending in _raw are 18-decimal integers as strings. Divide by 1e18 to get token amounts.
Output
Returns an array of auction day objects, each containing the day index, kind (license or charter), units offered and sold, raw prices (start, floor, close), half-life decay seconds, minutes to sellout, relevant timestamps (day start, first sale, last sale, sold-out), and the block number the data was captured at. Also returns top-level metadata: kind, basis, network name, chain ID, and current block.
Example use cases
Analyze TSR license price decay trend
“Get me the last 50 days of TSR license auction history so I can see how the starting prices and close prices have been trending over time.”
Track charter auction sell-through rate
“Fetch the auction day history for TSR charter auctions — I want to know how many charters were offered vs sold each day and whether any days failed to sell out.”
Identify fastest TSR sellout days
“Give me TSR license auction history and flag which days had the shortest minutes-to-sellout — I'm trying to figure out when demand for TSR licenses peaks.”

Endpoint
GEThttps://api.onesource.io/standard/v1/auctions/days?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need historical per-day auction analytics for The Standard Reserve protocol on Robinhood Chain (chain ID 4663), specifically for license or charter auction types. It is the right choice when you want price discovery data (open, floor, close), sell-through rates, sellout timing, or paginated day-by-day history. Prefer this over raw RPC calls when you need structured, pre-aggregated auction metrics rather than raw on-chain event logs.
Side effects
- Missing required 'kind' query parameter returns a 400 or validation error
- Invalid 'kind' value (not 'license' or 'charter') returns an enum validation error
- 'limit' out of range (0 or >500) returns a validation error
- 'before' value referencing a non-existent day returns an empty days array
- Payment failure via x402 / MPP returns a 402 Payment Required response
- Network or RPC node downtime returns a 503 or timeout
- Requesting data for a day before protocol launch returns an empty result
