Seneschal

Per-builder bid distribution (p25/median/p75/p90/p99/max) and hourly slot activity histogram from the Seneschal shadow recorder. Answers "what bid value do I need to land in builder X right now?" for searchers tuning bundle pricing.

Add $0.10 of credit (100_000 atomic USDC) to an existing watch. Body: { watchId, watchToken }. Returns the post-top-up credit block.

Create a Monero or Zcash view-key payment watch. Body: { chain, address, viewKey, webhookUrl, birthdayHeight? }. Returns { watchId, watchToken, webhookSecret, expiresAt, creditAtomic } — the receiver verifies inbound webhooks with HMAC-SHA256(webhookSecret, body) and tops up via /v1/private/topup* before the meter runs dry.
