https://api.seneschal.space/v1/q/at-risk-count
Single-fact: how many borrowers have HF < max_hf and debt >= min_debt_usd right now? Returns {count, total_debt_usd}.
https://api.seneschal.space/v1/q/base-fee
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).
https://api.seneschal.space/v1/q/block-value
Single-fact: network-wide percentile block value (proposer payment, ETH) across ALL winning slots in the window — the "is it worth bundling?" number, independent of builder. Returns {value_eth, median_eth, max_eth, samples}.
https://api.seneschal.space/v1/q/builder-bid
Single-fact: percentile bid value (in ETH) for `builder` over the window. Returns {value_eth, samples}.
https://api.seneschal.space/v1/q/liquidatable
Single-fact: is borrower X currently liquidatable? Returns {found, liquidatable, hf, debt_usd, last_seen_ms} sourced from Aave + Morpho snapshots.
https://api.seneschal.space/v1/q/proposer-payment
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).

https://api.seneschal.space/v1/q/xmr/last-block
Single-fact: timestamp + age of the most recent Monero block, plus hash, difficulty, and size.
https://api.seneschal.space/v1/q/xmr/mempool
Single-fact: number of pending transactions in the Monero mempool right now.
https://api.seneschal.space/v1/q/zec/height

The turnstile makes cross-pool flows public; this is the headline number. Sourced from a live operator-run zebra node.
