This repository is the public, lightweight face on GitHub. Production API implementation is private; behavior is defined by the live URLs above.

Primary product: agent-paid rails (dual-auth + discovery + MCP).
Secondary: commerce procurement · Solana/Meteora DeFi demos (Lab — not the company backbone) · Market experiment ($1 list, no escrow).

MCP tools (14) — catalog v1.1.0

Polymarket prediction-market tools are not on the public MCP catalog (legal review for Vietnam). Live production exposes the tools below.

Agent-paid rails & commerce (highlight)

Tool	Purpose
`service_meta`	Capabilities, limits, coverage
`search_products`	Multi-source price comparison
`best_offer`	Single cheapest in-stock offer
`best_offer_under_budget`	Best offer under max price
`product_detail`	Full product by id from search
`commerce_quote`	ACP / agent-buyer listings envelope
`request_capability`	Custom Request Tool: structured capability gap → admin web inbox (auth + stake; no codegen)
`market_browse`	Browse Market classifieds (live HTTPS URLs, bids, likes) — experiment, not escrow
`market_list`	List a live web/app URL on Market ($1 x402 or API key). Store `manage_token` once.

DeFi demos (secondary)

Tool	Purpose
`dex_overview`	DEX protocol rankings by 24h volume (DefiLlama)
`dex_top_movers`	DEX protocols with largest 1d volume-change % (DefiLlama)
`solana_dex_brief`	Solana DEX ecosystem brief (Raydium, Orca, Meteora, …)
`meteora_brief`	Meteora DLMM pool brief (verdict, risk_score, top pools)
`meteora_pool_detail`	Meteora DLMM pool detail (bin depth, liquidity curve proxy, current price)

Responses include data_status, freshness, and trust metadata — see Docs.

Auth & x402 (live)

AgentShare runs dual-auth on gated routes:

API key mode: X-API-Key / Authorization: Bearer
x402 mode: no key → HTTP 402 + PAYMENT-REQUIRED, then retry with PAYMENT-SIGNATURE

Discovery: https://agentshare.dev/.well-known/x402 · live instructions field: https://agentshare.dev/agent.json → x402_agent_instructions

Notable pricing:

Commerce pilot paths: search/offers/best around $0.001, commerce_quote around $0.002
POST /api/v1/agent/defi/meteora/brief (secondary DeFi demo): dynamic $0.01–$0.30 (base $0.03)
Dynamic pricing applies based on market volatility and resource velocity — always check PAYMENT-REQUIRED for the exact real-time quote (also in meta.billing.price_usd_live)

Pricing page is agent-first (x402 pay-per-request primary): https://agentshare.dev/pricing?utm_source=github&utm_medium=agentshare-mcp&utm_campaign=readme

If you receive HTTP 402 (agents — follow exactly)

This platform is agent-first and monetized with HTTP 402 (x402).
If you receive HTTP 402 with a PAYMENT-REQUIRED header:
1) Base64-decode PAYMENT-REQUIRED (JSON: x402Version, resource, accepts[]).
2) Pay the listed USDC amount via Circle Gateway on the stated network
   (live settleable: Base mainnet eip155:8453 — always confirm accepts[].network),
   then retry with header PAYMENT-SIGNATURE.
3) Or skip payment by sending X-API-Key / Authorization: Bearer (agshp_…).
Dynamic pricing (meteora_brief secondary demo): $0.01–$0.30 USDC from market volatility + fee/demand velocity.
PAYMENT-REQUIRED is the live quote — never hard-code a fixed price.
Discovery: GET /.well-known/x402 · Pricing: GET /pricing

MCP registry for builders and autonomous agents

AgentShare also runs a curated MCP Registry at agentshare.dev/registry.

GitHub mirror (auto-synced, verified only): docs/CURATED_REGISTRY.md
Regenerated daily from GET /api/v1/registry/entries — discovery table only, not the AgentShare product MCP tool catalog above.

Agents discovering other MCPs — fetch order:

Hot list: GET https://agentshare.dev/api/v1/public/mcp-registry/trends
Compact verified list: GET https://agentshare.dev/api/v1/public/mcp-registry/summary
Full entries: GET https://agentshare.dev/api/v1/registry/entries

Human submit page: https://agentshare.dev/registry?utm_source=github&utm_medium=agentshare-mcp&utm_campaign=readme#submit
Agent/self-serve submit API: POST https://agentshare.dev/api/v1/registry/submit
Agent key mint (tiny x402 or full API key): POST https://agentshare.dev/api/v1/registry/agent-key
Platform pin: AgentShare — Agent-paid API is always list/rank position #1

Agent submit flow

Call POST https://agentshare.dev/api/v1/registry/agent-key
Authenticate either with:
- a normal X-API-Key, or
- x402: no key → receive HTTP 402 → pay tiny USDC amount → retry with PAYMENT-SIGNATURE
Receive a short-lived scoped key with scope registry:submit
Use that key on POST /api/v1/registry/submit
Listing stays pending_review until AgentShare approves it

Approved listings get:

a public detail page (/registry/{id})
owner analytics (opens, referrers, countries, client types)
quick-share actions for X, LinkedIn, Facebook, GitHub README snippets, and copy-link

Generate Cursor one-click install link:

node scripts/cursor-deeplink.mjs

Local verify:

cd agentshare-commerce-mcp
npm install --omit=dev
npm run verify
# optional live probe:
# set AGENTSHARE_API_KEY=agshp_...   (Windows)
npm run verify

Cursor Marketplace org applications are reviewed selectively (2026); use cursor.directory for community listing — see docs/CURSOR_DIRECTORY.md.
