# Seneschal ZEC Supply by Value Pool

> Seneschal ZEC Supply by Value Pool is a paid API for AI agents from api.seneschal.space, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-15).

Returns the current Zcash (ZEC) total supply broken down by value pool (transparent, sprout, sapling, orchard, ironwood, lockbox) including NU6.3 Ironwood migration progress from a live zebra node.

## Facts

- Endpoint: GET https://api.seneschal.space/v1/q/zec/pools
- Price: $0.001/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-15

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 seneschal-zec-supply-by-value-pool-82dc33c9
```

Example prompt: What's the current Zcash supply split across all value pools — transparent, sapling, orchard, ironwood — and how far along is the NU6.3 Ironwood migration?

## When to prefer this

Use this endpoint when you need a single authoritative snapshot of ZEC supply distribution across all protocol-defined value pools, especially to track the NU6.3 Ironwood migration progress. Prefer this over block explorers when you need machine-readable pool-level data with shielding metrics. Best for agents monitoring Zcash protocol upgrades, privacy adoption rates, or supply analytics.

## Known failure modes

- Node sync lag: zebra node may be temporarily behind chain tip, returning slightly stale height
- Service unavailable: live operator node may be offline or under maintenance, returning 5xx
- Payment failure: x402 micropayment of $0.001 USDC not processed, returning 402
- Ironwood pool data absent: if mainnet Ironwood activation (~2026-07-21) has not yet occurred, ironwood fields may be null or absent

## How this service works

Single-fact: ZEC supply by value pool (transparent/sprout/sapling/orchard/ironwood/lockbox) + NU6.3 "Ironwood" migration readout — pool balance, Orchard remainder, and migration % once the quantum-recoverable Ironwood pool is live (mainnet target ~2026-07-21). The turnstile makes cross-pool flows public; this is the headline number. Sourced from a live operator-run zebra node.

## Output

A JSON object containing: total ZEC supply, per-pool balances (transparent/sprout/sapling/orchard/ironwood/lockbox), shielded ZEC amount and percentage, current block height, chain/network identifiers, a timestamp in milliseconds, and an ironwood sub-object with migration progress details including Orchard remainder and migration percentage.
