Seneschal Data

Service liveness plus which privacy-chain backends (Monero, Zcash) are configured on this server.

{
  "type": "object",
  "properties": {},
  "$schema": "http://json-schema.org/draft-07/schema#"
}

Returns the protocol, network, recipient address, and per-call price for every gated endpoint on this backend. Free to call. Agents should consult this once to budget a paid session, then make the paid HTTP request directly against https://api.seneschal.space (e.g. /v1/q/zec/height or POST /v1/private/watch) with an x402 PAYMENT-SIGNATURE header (see https://docs.x402.org).

}

Atomic single-fact endpoints designed for tight agent loops. Each answers ONE yes/no or one number — sub-50ms, flat $0.001/call at the REST surface. Privacy-chain facts from Seneschal-operated full nodes — Monero (xmr/height, xmr/mempool, xmr/fee, xmr/fee-estimate, xmr/last-block) and Zcash (zec/height, zec/mempool, zec/last-block, zec/pools) — plus Ethereum lookups (cheapest-flashloan, base-fee). Consult /v1/q for per-question input lists and live chain availability.

Subscribe a Monero or Zcash address to view-key-based payment monitoring. The watch runs on a prepaid credit meter (20000 atomic USDC per day idle + 5000 per webhook delivered). Creation at the REST surface (POST /v1/private/watch) is paywalled at $0.10 via x402 and seeds the watch with $0.10 of credit. Receiver gets HMAC-signed webhooks plus a 'credit' block on every body; a 'low_credit' warning fires once before the meter expires. Top up via /v1/private/topup, topup-1, or topup-5. View keys are AES-256-GCM encrypted at rest.

Add prepaid credit to an existing Private Watch. Three tiers — $0.10 (default), $1.00, and $5.00 — each settling at the matching REST path (/v1/private/topup, /topup-1, /topup-5). Credit is in atomic USDC ($0.02/day idle, $0.005/call). This tool returns the URL the agent should POST to with its x402 client; it does NOT settle payment itself.

The all-coin onboarding path: POST /v1/private/watch-crypto creates a Monero/Zcash payment watch AND returns a coin payment quote in one call — no x402, no USDC, no EVM wallet anywhere in the flow. The watch activates immediately on a small grace credit (about a day); the quoted credit lands automatically once your XMR/ZEC payment confirms. Returns the FREE endpoint + body to call. Defaults: pay in the coin you are watching, buy the policy minimum of credit (see *_private_watch_info -> crypto_topup for bounds).

Fund a Private Watch by paying in XMR or ZEC instead of USDC. Returns the FREE endpoint to call: POST /v1/private/topup-crypto issues a QUOTE — a receiving address, the exact coin amount to send (Monero: the amount carries a unique invoice tag; Zcash: a memo token), and a USD rate locked for a short window. Send the payment, then poll GET /v1/private/topup-crypto/{quoteId} (header x-watch-token) until status=settled. We detect the payment with the same view-key scanner the product sells and never hold a spend key. No x402, no API key — you pay in coin.

Accept an XMR/ZEC payment INTO YOUR OWN WALLET: creates a checkout invoice against your Private Watch (your address, your view key). Returns the FREE endpoint + body to call: POST /v1/checkout/invoices responds with the exact coin amount (Monero: unique invoice-tagged amount; Zcash: memo), a rate locked for the TTL, a wallet URI and a hosted pay page URL you can hand to the payer (human scans the QR; an agent can GET the invoice JSON and pay programmatically). When the payment confirms you get an invoice_paid webhook signed with your existing watch secret, and a flat settlement fee (~$0.02) is debited from the watch credit meter — never a percentage. Use your watchId+watchToken server-side, or a restricted checkoutKey (mint one with POST /v1/checkout/keys) anywhere you cannot keep secrets.

Poll the state of a checkout invoice: pending (waiting for payment) -> confirming (payment seen, counting confirmations) -> paid | underpaid | expired | cancelled. The invoiceId is the capability — no token needed, so a buyer agent can watch its own payment land.

Return all spendable + spent notes for a view key without setting up a watch. The view key never touches our SQLite — it flows through to NFPT in memory only. Use this when you want to reconcile a wallet at a point in time. Priced at $0.50 / call at the REST surface.

Hands a 12- or 24-word seed phrase to NFPT's orchard-scanner CLI, returns the matching UFVK. FREE but rate-limited to 6/minute/IP. Be loud about the security trade-off: the phrase transits our server (no logging, no persistence) but a network observer between you and us would see the bytes. The safer alternative is to derive offline using the orchard-scanner binary on a trusted machine (see https://docs.seneschal.space/derive-locally). A UFVK is read-only; it cannot spend funds.

For anything scheduled, bulk or latency-sensitive use https://api.seneschal.space/v1/private/historical (same scan, one paid x402 call) or — better — https://api.seneschal.space/v1/private/info to get a webhook when funds land instead of polling at all.

Open a scan of a Zcash UFVK. Returns { jobId, jobToken } in milliseconds — the scan itself runs behind it, so poll seneschal_zecmon_scan_status. Omitting birthdayHeight makes the scanner walk BACKWARDS from the chain tip to find the wallet's first note, which is slower but always correct. FREE and rate-limited (20 scan starts / 15 min, shared across all agents). For anything scheduled, bulk or latency-sensitive use https://api.seneschal.space/v1/private/historical (same scan, one paid x402 call) or — better — https://api.seneschal.space/v1/private/info to get a webhook when funds land instead of polling at all.

Poll a scan opened by zecmon_scan. Returns phase, progress and the notes found SO FAR — notes accumulate during the scan, so you can read them before it finishes. During "detecting-birthday" the response carries the descending backwards window; during "scanning" it carries birthday → tip coverage. Poll no faster than every 1.5s. Free.

Stop a running scan and release the scanner slot. Do this as soon as you stop caring about a scan — concurrency is finite and an abandoned chain walk blocks someone else. Free.

Curated catalogue of Ethereum mainnet flash-loan providers (incl. Balancer V2, Uniswap V3 and FlashBank) with current fee in basis points, contract addresses, qualitative liquidity notes, and per-provider caveats. Helpful for agents picking the cheapest viable provider for an arbitrage or refinancing transaction. The catalogue is editorially open: filter by chain, max fee, or multi-asset support.

Terse, drill-down discovery index of this ecosystem (Seneschal, FlashBank, winbit32, secresea, ZecBus, Zecmon, Ziving, McPai) plus a LIVE mirror of the official MCP registry (registry.modelcontextprotocol.io) — the same directory served over HTTPS at https://seneschal.space/.well-known/agent.gopher, callable here so you never leave the MCP session. Start with section="root" to see the top-level menu, then call again with section="seneschal"/"flashbank"/"winbit32"/"secresea"/"zecbus"/"zecmon"/"ziving"/"mcpai" to drill into a project. Each project exposes About / Agents / Actions — drill them with section="<site>/about", "<site>/agents" or "<site>/actions" (e.g. "winbit32/actions"). Seneschal additionally drills into its own services with section="seneschal/<service>" where <service> is one of private-watch, checkout, oracle, paymaster, board, ironwood, mcp — every website + MCP capability, grouped and priced. section="registry" browses connectable third-party MCP servers (use `cursor` to page); section="about"/"agents" is the directory’s own prose. format="gopher" (default) is the compact RFC-1436 menu; format="json" returns a structured {title, items[]}. A discovery layer, not a replacement for MCP — use it to FIND tools, then connect. Free, no payment.
