The current state of AI agent API integration is a mess of broken discovery and stale directories. An agent needing a paid endpoint today faces three bad options: finding an undiscoverable endpoint, trusting a frozen directory, or using a free index that can find but not sell. ScriptMasterLabs has launched HIVE402 to fix this, introducing a live x402 marketplace where the entire catalog is purchasable directly inside the Model Context Protocol (MCP). The service is now published on the official MCP Registry as com.scriptmasterlabs/hive402 (v1.0.5, active).

Measured Catalog Size vs. Marketing Hype

HIVE402 claims to be the fourth option, backed by hard data rather than vague promises. As of November 12, 2026, the marketplace lists 31,377 paid endpoints across 1,640 operators. Crucially, 4,495 of these are probe-verified, meaning an unpaid check confirms the endpoint still returns a valid x402 challenge. Prices range from $0.0005 to $1,000 per call across five rails: Base (USDC), Arc (USDC), XRPL (XRP, RLUSD), Xahau (XAH), and Solana (USDC). This scale dwarfs competitors; the largest verified purchasable catalogs in the registry after HIVE402 sit at just 185 tools and 177 endpoints.

No-Account Purchase Flow

The integration path is streamlined for autonomous agents, requiring no traditional account setup. HIVE402 exposes 10 MCP tools, with the purchase flow relying on three: search_catalog to filter by task, network, and max price; get_listing to inspect live terms; and start_purchase to fetch the x402 challenge. The caller signs and pays with its own wallet. Settlement is handled by OMNIGATE for USDC on Base and Arc, or 402Proof for other rails. The system is designed to fail closed: if no rail settles, nothing is delivered, preventing free abuse.

Fee Structure and On-Chain Proof

ScriptMasterLabs takes no custody of funds, settling guest sellers directly to their wallets. Listing an endpoint is free, and there is a 0% fee on endpoint sales. The platform’s only revenue source is a 10% charge on completed Mission payments for budgeted multi-step work. Additionally, 402Proof charges a $0.0100 seller settlement fee. Every settlement mints a soulbound receipt token on the Base contract 0x70f215F2A94410642bf5DBcfc7B2384F47392FA6, providing an immutable, on-chain proof of purchase. This contrasts sharply with alternatives like PulseMCP, which has had listing changes paused since September 2026, or Glama, which recently mirrored a two-versions-old catalog count.

Independent Verification and Registry Status

On November 12, HIVE402 became the first verified agent on AgentIndex, receiving an audit score of 85 and an "operational" verdict. Its OpenAPI, x402 manifest, agent card, and MCP manifest all returned 200 status codes. This canonical discovery record allows downstream directories to ingest accurate data, with Glama already mirroring HIVE402’s tools graded A for definition quality. The team proved the end-to-end path with a self-proof purchase of their own Coherence Spend Gate for $0.005 USDC on Base, transaction 0xc2aa5d976b73ace16d6990982e610422947d2352dd698bfed0aea98404b0.

Key Takeaways

  • HIVE402 offers 31,377 paid endpoints, orders of magnitude larger than competitors.
  • Purchase flow requires no account, using three specific MCP tools for search and settlement.
  • Platform fees are 0% on endpoint sales, with a 10% take only on Mission payments.
  • All settlements generate soulbound on-chain receipts for verification.
  • The service is verified on AgentIndex with an operational status and audit score of 85.

The Bottom Line

HIVE402 finally bridges the gap between discovery and transaction for AI agents, offering a rare combination of scale, transparency, and autonomous payment capability that competitors have failed to deliver.
