Nibgate tools (5)

write = sends, deletes, buys or posts
  • explore_contentFree

    Search verified creator content on Nibgate. Returns content metadata (title, type, price, domain, reputation, unlock path). Use to discover what paid/free content exists.

    Get ranked creators, sites, or content by reputation score, unlocks, views, and revenue (unlocks + tips + nibshares).

  • get_ledgerFree

    Get the public Nibgate activity ledger: recent views, unlocks, payments, tips (including funded pending holds marked status=held), onchain ratings, and privacy-safe nibshare views/unlocks (titles, wallets, amounts, tx — never the private share link) across verified sites. Held tips are pending and do not count toward completed-tip totals; refunds appear as negative tip entries. Use GET /hub/tips/held?domain={domain} to check pending tips for any exact domain, including external sites. Includes wallet addresses, tx hashes, and receipts where available.

  • resolve_shareFree

    Resolve a Nibshare link (https://nibgate.xyz/ns/<slug> or a bare slug) to its machine-readable manifest: title, price, currency, content type, status, expiry, and the page/access/unlock/media URLs. Use before attempting payment or access.

Nibgate — open protocol for paid content

Website | Docs | X

Nibgate is a verified content discovery, unlock, and reputation layer for creator-owned work. Creators keep their content on their own domains. Nibgate verifies the source, indexes structured public metadata, records unlock/payment signals, and helps humans and AI agents discover quality content without moving it into a closed marketplace.

Built on ARC testnet and the x402 protocol, with two payment rails: Circle Gateway (EIP-3009 facilitator) and direct USDC transfer to the creator's receiver.

Key packages:

  • SDK (packages/nibgate/) — @nibgate/sdk npm package for gating paid content on any creator site. Browser and server entrypoints, x402/Gateway unlocks, event streaming, onchain ratings. Includes the shared access-control rule (canAccess, normalizeWhitelist, paidCutoffWallets) used by both rails and the encryption primitives (crypto.js).
  • Wallet (packages/wallet/) — @nibgate/wallet npm package with a ./react entry: shared Reown AppKit (AppKit + wagmi) wallet provider, SIWE sign-in, and the /GatewayWallet single-checkout used by the hub header, Nibshare, and Subblogs.
  • Subblogs (subblogs/) — Full blog platform for creators at *.nibgate.xyz. Articles, photos, music, video, documents, free and paid posts. Next.js frontend (port 3002), Express backend (port 4000), PostgreSQL. SIWE wallet auth, whitelists/invite-only tiers, AES-256-GCM encryption at rest.
  • Hub (frontend/ + backend/) — The main nibgate.xyz app: public site, creator dashboard, Explore discovery, analytics, API, Nibshare quick-share rail, and widget hosting.
  • CLI (packages/cli/) — Internal tooling for local dev, site verification, and hub connection.
  • Docs (docs/) — Documentation site at docs.nibgate.xyz.

Product Thesis

The open web needs a content discovery standard for paid, high-quality resources. Nibgate provides the verified layer that says:

  1. this domain is controlled by this creator
  2. this content exists at this route
  3. this content can be unlocked by humans or agents
  4. this creator has real reputation signals from verified activity
  5. this payment history routes directly to the configured receiver for the resource

The creator-owned site remains the source of truth, while the hub becomes the public index, analytics surface, and reputation graph around verified content.

It consists of four connected parts:

  1. The Widget: Creators paste one script on their site. It proves domain ownership, creates visitor/session context, and sends browser-safe page activity to Nibgate.
  2. The Package: Creators install the @nibgate/sdk npm package to gate real content on their own site. The package knows the content, unlock, and payment lifecycle, then reports those events through the widget bridge.
  3. The Hub: nibgate.xyz is the creator dashboard, discovery surface, and analytics layer. It verifies sites, stores content metadata, aggregates metrics, and shows profile/site/content/earnings data.
  4. The Discovery Layer: Explore, public profiles, content metadata, receipts, and reputation signals make verified creator content readable by people and AI agents.
