DPYC Oracle — community concierge for the DPYC Social Contract.

DPYC ("Don't Pester Your Customer") is a philosophy and protocol for API monetization via Bitcoin Lightning micropayments. Users pre-fund a satoshi balance and consume API calls without KYC, stablecoins, or mid-session payment popups. Identity is a Nostr keypair (npub), not an email or username. Tollbooth monetizes complete business information at the MCP tool layer — not raw REST data fragments — using pre-funded Lightning balances that eliminate per-request payment ceremonies.

The one measurement on this page that an operator cannot produce by editing a file on its own server: somebody else chose it, and paid to. Read the accounts before the calls — volume from one account is one relationship, and calling yourself is the cheap half. Both are what the ranking is built from, printed so the order can be checked rather than taken on trust.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

get_relays open 8h ago
Return the DPYC Nostr relay set, best first. The single source of truth is ``dpyc-community/relays.json``. An Operator seeds its relay set from here at cold start (its only fixed dependency is this Oracle endpoint), then reads its own bootstrap config from Nostr using just its nsec — no direct GitHub access. That file is a curated *guess*: it says which relays are worth using, not which are up this minute. Relays that an operator reported and the Oracle then proved unreachable are moved to the back of the list; everything else keeps its declared order, and nothing is ever dropped. This call never probes anything — it is on every operator's cold-start path, so it stays a lookup. Ranking improves only when someone hits a dead relay and says so via ``report_relay_failure``. Report failures only; successes need no announcement. Free.

arguments 5 lines
get_tax_rate open 8h ago
Explain how Tollbooth certification taxation works. Taxation is ad valorem and **per-Authority** — there is no single network-wide number, and the Oracle deliberately quotes none. The actual fee is the Authority's own accounting, set in its pricing model and reported at transaction time. This tool is a docent: it explains the model and points to the live source. For the exact figure, query the relevant Authority's ``check_price`` for ``certify_credits``.

deregister_operator unknown never probed

Remove an Operator from the DPYC community registry. Called when an Authority disowns an Operator. An Operator cannot exist without a sponsoring Authority, so deregistration removes the member file entirely, returning the Operator to initial state.

arguments 5 lines
lookup_member unknown never probed
Look up a member by their Nostr npub. Can look up any role's npub — citizen, operator, or authority. Returns the full member record if found, or a not-found message.

mcp-tool

arguments 12 lines
resolve_service unknown never probed
Resolve a DPYC service by ``name`` or ``npub``. Returns ``{npub, url, name, role, purchase_mode}`` where ``purchase_mode`` is the registry-topology fact ``"certified"`` or ``"direct"`` (not a price). Supply exactly one of ``name`` or ``npub``.

arguments 14 lines
request_citizenship unknown never probed
Begin the citizen registration process (Operator-owned flow). This is the **citizen** registration path. Called by the Operator on behalf of a patron — invokes the Oracle directly. No Authority npub is required or consulted. The patron's npub is registered as a Citizen in the DPYC community. The npub provided here becomes the user's **patron identity** — the keypair they will use for credit purchases and service access across all Tollbooth-monetized services. Not to be confused with **operator** registration, which goes through the Authority via a Nostr DM delegation request. Issues a cryptographic challenge that the applicant must sign with their Nostr private key (nsec) to prove they own the claimed npub. The nsec never leaves the applicant's device. Returns a challenge_id, nonce, and signing instructions. The applicant signs a Nostr event containing the nonce and submits it via confirm_citizenship within 10 minutes.

mcp-tool

arguments 16 lines
confirm_citizenship unknown never probed
Complete the citizen registration by submitting a signed Nostr event. This is part of the **citizen** registration flow (Operator-owned). The Operator calls this on behalf of a patron after the patron has signed the cryptographic challenge from request_citizenship. Verifies: 1. The challenge exists and hasn't expired 2. The Schnorr signature is valid 3. The event's pubkey matches the claimed npub 4. The event content contains the issued nonce 5. The npub is not already registered On success, commits directly to dpyc-community/members/citizens/{npub}.json to register the new Citizen immediately.

arguments 20 lines
resolve_authority_for unknown never probed
Resolve the certifying Authority for an operator npub. Returns the Authority's ``{npub, url, name}`` (from the operator's ``upstream_authority_npub``). Use this after bootstrap to learn — and verify — which Authority signed your config, without reading GitHub.

how_to_add_authority unknown never probed
End-to-end guide for spinning up a new Tollbooth Authority. Returns the eight-step procedure covering identity, region selection, GitHub workspace, dpyc-community registry entry, Neon + BTCPay + Horizon deployment, BTCPay credential delivery via Secure Courier, the self-registration challenge-response with the parent Authority, and pre-funding the cert-fee balance. Fetched live from docs/how-to-add-authority.md in the dpyc-community repo.

Diagnostic: report this service's software versions and runtime info. Free, unauthenticated. Use to verify deployment versions across the DPYC ecosystem.

mcp-tool
{ "type": "object", "properties": {}, "additionalProperties": false }
arguments 5 lines
list_services unknown never probed
Enumerate the live DPYC service network with self-described summaries. Reads the member roster from the dpyc-community registry, then (when ``probe=True``) performs a lightweight MCP handshake against each member's public service endpoint to fetch that service's *own* self-description and tool inventory. Nothing about the services is hardcoded here — descriptions are authored by each service, and prices come from each Operator/Authority pricing model (call the service's ``check_price``). Resilient by design: per-service timeout, partial results, brief caching, and a registry-only fallback when an endpoint is asleep or unreachable. A sleeping service never breaks the listing. Free, unauthenticated.

arguments 16 lines

report_relay_failure unknown never probed

Report that a relay in the DPYC set was unreachable, and re-rank it. A report does not set a relay's rank. It asks the Oracle to measure that relay *now*, and the Oracle's own probe decides. A false or mistaken report therefore costs one probe and changes nothing — no caller can demote a healthy relay by asserting that it is down. Report only failures. Successes are far too frequent to be worth carrying, and a relay that works needs no announcement.

economic_model unknown never probed
Explain the DPYC Social Contract economic model — qualitatively. Describes how value flows through the network: ad valorem certification fees, the cascade up the Certification Chain to the First Curator, and where the live numbers actually live. The Oracle quotes **no** rates, counts, or revenue figures — those belong to the Authorities' pricing models and the live registry, not to a docent. Free, unauthenticated.

arguments 5 lines

register_authority unknown never probed

Register a new Authority in the DPYC community registry. Called by an Authority service at the end of the onboarding protocol (after the candidate proves npub ownership and the Prime Authority approves). Commits a new ``members/authorities/{npub}.json`` file to dpyc-community on GitHub. The full Authority onboarding protocol is a 3-step Nostr DM challenge-response flow: 1. ``register_authority_npub(npub)`` — Authority sends DM challenge 2. ``confirm_authority_claim(npub)`` — verifies candidate DM, escalates to Prime 3. ``check_authority_approval(npub)`` — Prime approves, this tool is called

register_advocate unknown never probed

Register a new Advocate in the DPYC community registry. Advocates are community utility services that provide shared infrastructure (e.g., OAuth2 callback collectors) but aren't monetized Operators or certification Authorities. This is an Oracle-mediated registration — no Nostr DM challenge-response needed. The Oracle operator (Prime Authority) trusts the commit via GitHub token.
