What this server can do
16 functions, named and described by the server itself. Parameter names are shown because they say more about what a function does than its name usually does.
activate_pro_tier(agent_id, payment_required, payment_signature)- Verify pro-tier x402 payment and unlock Pro quota limits. Required: payment_signature, payment_required.
build_seller_requirements(price, pay_to, scheme, network, agent_id, mime_type, description, discoverable, resource_url, discovery_method, discovery_input_example, discovery_output_example)- Build seller-side x402 payment requirements via x402ResourceServer. Pass resource_url (plus optional discovery_* fields) to embed the Bazaar discovery extension so a settled payment catalogs the endpoint.
create_stripe_checkout(credits, purpose, agent_id)- Create Stripe Checkout Session for pro tier or tool credits (fiat rail).
discover_services(limit, query, agent_id, max_price_usdc)- Discover x402 Bazaar paid HTTP services via x402 HTTPFacilitatorClient.
get_base_pulse(depth, agent_id)- Live Base Network Pulse: synthesized settlement-conditions intelligence (base fee, EIP-1559 projection, utilization trend, USD settlement cost, and a settle-now/hold verdict) computed from real Base RPC data + ETH spot price.
get_os_metrics(agent_id, include_processes)- Host OS telemetry: CPU, memory, swap, disk, network, and process signals with an ok/warn/critical health verdict, sampled live from the machine running the server. Optionally includes the top processes by memory.
get_payment_requirements(url, method, headers, agent_id)- Probe a URL for x402 payment requirements using x402HTTPClient SDK. Required: url.
get_pro_upgrade_requirements(agent_id)- Build x402 payment requirements to purchase Pro tier (revenue collection).
get_supported_networks(agent_id)- List networks, facilitators, and v2 headers via x402 SDK.
get_tool_credits_requirements(credits, agent_id)- Build x402 payment requirements to purchase per-use MCP tool credits.
pay_and_fetch(url, body, method, headers, agent_id, max_price_usdc, preferred_network)- Pay via x402HttpxClient and fetch a protected HTTP resource. Required: url.
purchase_tool_credits(credits, agent_id, payment_required, payment_signature)- Verify x402 payment and add per-use tool credits (per-call revenue path). Required: payment_signature, payment_required.
run_swarm_research(topic, agent_id, max_price_usdc, allow_paid_inputs)- Run the swarm Agency: compose a research product and list it for resale. Spends nothing by default — the report is synthesized from free inputs, so unsold inventory costs nothing. Pass allow_paid_inputs=True to buy upstream x402 services first (buy → compose → list), which books a cost basis before knowing whether the composite will sell. Required: topic.
settle_composite_sale(agent_id, product_id, payment_required, payment_signature)- Verify + settle a buyer's x402 payment for a listed composite product and record the realized revenue (sell side). Required: product_id, payment_signature, payment_required.
swarm_revenue_report(agent_id)- Portfolio revenue intelligence for the swarm: spend, revenue, LTV:CAC, margins, per-source profit scores.
verify_payment_payload(agent_id, payment_required, payment_signature)- Verify PAYMENT-SIGNATURE via x402ResourceServer + facilitator. Required: payment_signature, payment_required.

These are separate measurements of different things. They are deliberately not combined into one score, because a popularity number that mixes website traffic with saves and stars cannot be checked or acted on.
