# The Standard Reserve (TSR) Issuance Runway

> The Standard Reserve (TSR) Issuance Runway is a paid API for AI agents from api.onesource.io, paid per call via x402, $0.02/call, status unknown (last checked 2026-10-13).

Returns cumulative STANDARD token issuance, current issuance rate, budget remaining, and a projected date when the on-chain issuance budget will be exhausted on Robinhood Chain.

## Facts

- Endpoint: GET https://api.onesource.io/standard/v1/issuance/runway?utm_source=zero.xyz
- Price: $0.02/call
- Payment: x402
- Status: unknown

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability the-standard-reserve-tsr-issuance-runway-cecaf99a
```

Example prompt: How much of the STANDARD token issuance budget has been used so far on Robinhood Chain, what's the current issuance rate per second, and when is it projected to run out at the current pace?

## When to prefer this

Choose this endpoint when you need a real-time, on-chain snapshot of STANDARD token issuance status on Robinhood Chain — specifically the cumulative issuance, remaining budget, live streaming rate, and projected runway date. It is the canonical source for TSR issuance analytics without needing to construct raw eth_call queries yourself.

## Known failure modes

- Network or RPC unavailability on Robinhood Chain may cause stale or missing block data
- Payment failure (x402) if the $0.02 USDC per-call fee is not included or is insufficient
- If the policy multiplier changes, the projection may immediately become outdated (the response includes an assumption disclaimer)
- Unexpected contract state changes could return zero or inconsistent values for budget/rate fields

## How this service works

The Standard Reserve (TSR), an on-chain reserve protocol on Robinhood Chain. Cumulative STANDARD issuance against its budget, the current issuance rate, and a current-pace projection of when the budget runs out. Fields ending in _raw are 18-decimal integers as strings. Divide by 1e18 to get token amounts.

## Output

Returns a JSON object with the Robinhood Chain ID (4663), the block at which the snapshot was taken, cumulative STANDARD tokens issued, total issuance budget, remaining budget, the current stream rate in tokens/second, and a projected exhaustion date and seconds-remaining — all token amounts as 18-decimal integer strings (divide by 1e18 for human-readable values).
