Seneschal

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.

Single-fact: recommended Monero per-byte fee in piconero (also exposed per-kB for convenience).

Single-fact: how many borrowers have HF < max_hf and debt >= min_debt_usd right now? Returns {count, total_debt_usd}.

Single-fact: what does Ethereum mainnet gas cost RIGHT NOW? Returns the latest block’s base fee + blob base fee AND the consensus-computed next-block projection (not a guess — the protocol’s own EIP-1559/4844 arithmetic), straight from eth_feeHistory. Fields: {block, base_fee_gwei, blob_base_fee_gwei, gas_used_ratio, next_base_fee_gwei, next_blob_base_fee_gwei}. Bulk per-block history: /v1/premium/fee-history.csv ($0.05, up to 1024 blocks/call).

Single-fact: current Monero chain height + sync status. Sourced from a live operator-run monerod node.

Single-fact: what did the proposer of the latest block ACTUALLY get paid (priority fees + direct coinbase transfers — the value that reaches the validator, not the noisy block-value proxy)? Returns {block, proposer_payment_eth, builder, tx_count} plus a 1h aggregate {samples, mean_eth, median_eth, p90_eth, max_eth}. Per-block history export: /v1/premium/builder-bids.csv ($0.05, CSV or JSONL).

Single-fact: how many on-chain liquidations have we observed in the last `since_min` minutes, with what aggregate debt? Returns {count, total_debt_usd}.

Single-fact: which builder has the largest slot share in the named window (24h|7d|30d)? Returns {builder, share_pct, slots_won}.

Single-fact: timestamp + age of the most recent Monero block, plus hash, difficulty, and size.

Single-fact: current Zcash chain height + verification progress + best block hash. Sourced from a live operator-run zebra node.

Single-fact: Zcash mempool count + bytes.

Single-fact: number of pending transactions in the Monero mempool right now.

Single-fact: timestamp + age of the most recent Zcash block, plus hash, difficulty, and size.
