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
service_meta	Capabilities, limits, coverage
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)

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:

• POST /api/v1/agent/defi/meteora/brief (hot path): 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)
• Commerce pilot paths: search/offers/best around $0.001, commerce_quote around $0.002

Pricing page is now agent-first (x402 pay-per-request primary): https://agentshare.dev/pricing

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
   (pilot: Base Sepolia eip155:84532), then retry with header PAYMENT-SIGNATURE.
3) Or skip payment by sending X-API-Key / Authorization: Bearer (agshp_…).
Dynamic pricing (meteora_brief): $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 https://agentshare.dev/registry

• Browse verified listings: GET https://agentshare.dev/api/v1/registry/entries
• Human submit page: https://agentshare.dev/registry#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

Agent submit flow

1. Call POST https://agentshare.dev/api/v1/registry/agent-key
2. Authenticate either with:
   • a normal X-API-Key, or
   • x402: no key → receive HTTP 402 → pay tiny USDC amount → retry with PAYMENT-SIGNATURE
3. Receive a short-lived scoped key with scope registry:submit
4. Use that key on POST /api/v1/registry/submit
5. 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
