ScriptMasterLabs' HIVE402 lists 153 paid endpoints from 15 sellers across 5 payment rails — Base, Arc, XRPL, Xahau, and Solana — counted on the live marketplace on November 10, 2026. Two ScriptMasterLabs facilitators settle everything in the catalog: OMNIGATE moves USDC on Base and Arc, and 402Proof settles on XRPL, Xahau, and Solana.
On November 10, 2026, 402Proof seller signup went self-serve: a seller publishes an ownership-proof file on their own website and receives a partner key automatically. What was an invite-only facilitator door the day before is now an open one — and HIVE402 is the marketplace standing behind it.
Canonical version: scriptmasterlabs.com/hive402
Pricing at a glance
Listing an endpoint on HIVE402 is free. Endpoint prices are set by each seller and are paid per call in the rail's asset. 402Proof's facilitator fee is $0.0100 per settlement. The fee is accrued — recorded against the seller — and is never deducted from the buyer's payment. Collection of accrued fees is not switched on. Verifications, failed settlements, and replays are free: if nothing settles, nothing accrues. Self-serve partner keys are capped at 10 XRP per payment; larger ceilings stay on the operator invite path. One active partner key is allowed per proven website. Fee and cap figures verified November 10, 2026.
How an agent buys: four tools, no auth, no custody
HIVE402's agent door is an MCP server at https://hive402.scriptmasterlabs.com/mcp. It answers with no authentication and no API key, and it exposes exactly four tools:
-
search_catalog— finds paid endpoints in the catalog by what the agent needs done. -
get_listing— reads one listing: the endpoint, its per-call price, and the rail it settles on. -
start_purchase— returns the endpoint's live x402 payment challenge — the real payment terms, not a quote. -
list_endpoint— lets a seller add a real endpoint to the catalog through the same server buyers use.
The buyer signs every payment with its own wallet. ScriptMasterLabs takes no custody of buyer funds and holds no buyer keys. An outside agent does not need an account, an invite, or a sales call to spend money in this catalog — it needs a wallet and the MCP address.
The news: 402Proof signup is self-serve as of November 10, 2026
Until today, a seller who wanted to settle through 402Proof needed an operator-issued invite. That gate is gone. The live flow on the HIVE402 seller page (hive402.scriptmasterlabs.com/apply) is:
- Request the signup. Seller name, contact, website origin, XRPL receiving address, maximum payment amount — and explicit acceptance of the $0.0100 per-settlement fee, before any key exists.
- Publish the proof file. 402Proof returns a one-time ownership-proof file (valid 30 minutes). The seller places it on their own website, proving they control the origin the key will be pinned to.
- Receive the partner key automatically. Once the proof verifies, the key is issued. On the ledger it exists only as a hash, it is pinned to the proven website and the stated payout address, and amounts above the key's ceiling are rejected before any chain call.
Then the seller lists endpoints — through the MCP list_endpoint tool or the seller dashboard — and settlements through 402Proof accrue the $0.0100 fee per completed settlement, exactly as the accepted terms state.
Proof: what has actually run (SELF-PROOF where ours)
The canary (SELF-PROOF). ScriptMasterLabs proved the new door end-to-end on November 10, 2026 with its own canary signup, using scriptmasterlabs.com as the seller origin: a request for a 100 XRP ceiling was issued at the 10 XRP self-serve cap, the issued key authenticated, out-of-scope payment attempts were rejected on both payee and amount, and the key was then revoked and confirmed dead. No funds settled. This is ScriptMasterLabs testing its own door with its own origin — labeled SELF-PROOF, not a third-party adoption claim.
Outside money (verified). On 2026-11-09 an outside agent wallet settled 0.01 USDC through OMNIGATE for a ScriptMasterLabs endpoint — transaction-verified.
The honest flag. 402Proof's public record still shows external third-party settlements as not yet verified. The canary was ours. That flag flips only when a genuinely external seller settles end-to-end — and the canonical page will be re-stamped when it does.
HIVE402 vs the largest catalog: the explicit comparison
ScriptMasterLabs' market check of November 10, 2026 counted roughly 4,200 services on Coinbase's Agentic.Market — every one of them settling through Coinbase's own CDP facilitator, with sellers appearing by settling through that one facilitator. HIVE402 is far smaller and built the other way: it is the catalog our check found combining EVM rails (Base and Arc) and non-EVM rails (XRPL and Xahau) across two independent facilitators inside one no-auth MCP purchase flow.
| Coinbase Agentic.Market | ScriptMasterLabs HIVE402 | |
|---|---|---|
| Catalog size | ~4,200 services (ScriptMasterLabs market check, November 10, 2026) | 153 paid endpoints, 15 sellers (live count, November 10, 2026) |
| Facilitators | One — Coinbase's own CDP facilitator settles everything | Two independent facilitators — OMNIGATE and 402Proof |
| Rails | Settles through the CDP facilitator | 5 rails in one catalog: Base, Arc, XRPL, Xahau, Solana |
| How an agent buys | Discovery through Bazaar metadata | No-auth MCP: search_catalog → get_listing → start_purchase returns the live payment challenge |
| How a seller gets in | By settling through the CDP facilitator | Self-serve: publish an ownership-proof file, receive a partner key (402Proof, live November 10, 2026); list through the same MCP |
| Custody | — | None: the buyer signs with its own wallet |
The trade is stated plainly: the big catalog wins on size. HIVE402 wins where a single-vendor rail set is the constraint — an XRPL seller and a Base buyer meet in one catalog, behind one MCP address, without either of them routing through a facilitator neither chose.

Honest caveats
- Scale. 153 endpoints is a small catalog next to the ~4,200 services our November 10, 2026 check counted on the largest one. HIVE402's difference is rail breadth across two independent facilitators, not size — said here instead of hidden.
- Accrued is not collected. The $0.0100 402Proof fee is recorded per settlement; collection is not switched on, and accrued fees are not collected cash.
- Proof labels. The signup canary is SELF-PROOF (ScriptMasterLabs' own origin and key). The one outside-money settlement named here is transaction-verified; no other adoption is claimed.
