Dexter Upgrades the x402 App Store for Real Agent Discovery

Dexter Upgrades the x402 App Store for Real Agent Discovery

FOR IMMEDIATE RELEASE

Dexter Ships a Major x402 App Store Upgrade with Production-Grade Ranking, Full MCP Parity, and Smarter Endpoint Quality Signals

The x402 App Store now behaves like a real store, not a raw settlement leaderboard.

The Upgrade

FEBRUARY 2026 — Dexter, the facilitator behind millions of x402 settlements, today announces a major upgrade to the Dexter x402 App Store across its Open and authenticated MCP surfaces.

This release focuses on the three things agent developers care about most: discovery quality, endpoint reliability, and consistent behavior across every Dexter MCP surface.

What's New

1) x402_search now ranks like an app store feed

Default search is no longer a single-dimensional sort by settlement count.

Dexter now uses a multi-signal ranking model that prioritizes:

  • Verified quality (verification status + quality score)
  • Freshness (recently active and recently verified services)
  • Usage (settlements and volume, log-scaled to avoid pure whale dominance)
  • Seller trust (reputation signals)
  • Reliability and value (failure penalties and price-aware boosts)

Top results are also diversified to reduce repetitive seller/category clustering and improve browse quality.

2) Full x402 tool parity across all three MCP surfaces

Dexter now verifies and aligns x402 behavior across:

  • OpenDexter (open.dexter.cash/mcp)
  • Dexter Authenticated MCP (dexter.cash/mcp)
  • Dexter x402 package/runtime surface (@dexterai/mcp)

Core x402 tools are now synchronized:

  • x402_search
  • x402_check
  • x402_fetch
  • x402_pay
  • x402_wallet

3) Auth-aware endpoint handling for cleaner UX

Some providers gate access with their own auth before x402 payment negotiation.

Dexter now surfaces this explicitly:

  • x402_check returns explicit authRequired signaling for 401/403 paths
  • marketplace responses include auth metadata for UI/tooling clarity
  • auth-gated flows can be filtered or labeled cleanly instead of failing silently

4) Better verifier intelligence for stricter APIs

Dexter's endpoint verifier now uses stronger schema-aware and host-aware strategies, including method overrides and stricter payload shaping for difficult provider integrations.

This directly improves which endpoints are promoted as high-quality in search and reduces inconclusive verification noise.

Why This Matters

An agent app store is only useful when:

  1. Discovery is actually good
  2. Listings are quality-scored by real execution
  3. Every MCP surface behaves the same way

This upgrade addresses all three.

Agents now get faster discovery, cleaner execution paths, and a more trustworthy catalog from the same x402_search and x402 payment workflow.

Three Ways In

SurfaceAuthPaymentBest For
open.dexter.cashNoneAgent brings own walletAny agent, anywhere — instant discovery
mcp.dexter.cashDexter OAuthAutomatic (managed wallet)Agents with Dexter accounts — zero-config payments
ClawDexter pluginOpenClaw configAutomatic (user's wallet key)OpenClaw users — native integration

All three surfaces now point to the same upgraded marketplace behavior.

How It Works

1. Connect

Point any MCP client at:

https://open.dexter.cash/mcp

Or use the authenticated endpoint:

https://mcp.dexter.cash/mcp

2. Search

Call x402_search to discover paid APIs with ranked relevance, quality, and trust context.

3. Check and Pay

Use x402_check to inspect pricing and requirements, then call with x402_fetch or x402_pay depending on runtime surface and wallet mode.

The Agent App Store, Now Operationally Mature

The conversation has moved from "who will build the app store for agents?" to "which one actually performs under production pressure."

Dexter's answer is a marketplace that is:

  • open to any MCP-compatible agent
  • quality-ranked with real verification
  • synchronized across Open, authenticated, and package-based runtime surfaces

The storefront is live, checkout works, and ranking now supports real agent workflows.
