• POST /v1/task-state-transition-gate — Reject illegal task-state changes and terminal-state regressions before an orchestrator mutates durable MCP/A2A-style task state. (0.005 USDC on Solana)

• POST /v1/release-sentinel-evidence — Live, independent npm dependency release risk evidence for non-AI package managers, CI/CD runners and deployment controllers. Check pinned sha512 integrity, lifecycle scripts, optional npm signature/provenance metadata and known OSV vulnerabilities before installing an exact package version. Live registry+OSV preflight runs prior to payment settlement, and errors prevent fulfillment; buyer authorization is required. (0.049 USDC on Base)

• execute_paid_product — Native x402 v2 MCP payment transport. Choose product_id and input. The first call returns PaymentRequired without executing paid work. An x402-capable MCP buyer retries the same call with its signed PaymentPayload in params._meta['x402/payment']; a successful result includes _meta['x402/payment-response']. No browser or human checkout is required. Example: {product_id:'hash',input:{text:'hello'}}.
• get_product_proof — Return one product's method, exact price, schema, sample input and autonomous purchase contract without spending funds. Example: {product_id:'web-extract'}.
• get_purchase_instructions — Return the direct endpoint, price, payment network and purchase flow for one Bounty Engineer product. Does not spend funds. Example: {product_id:'x402-payment-preflight'}.
• get_workflow_recipe — Get published sample input/output, exact credits for a batch, one-time pack options and prepaid HTTP integration. No payment or own-data execution occurs. Example: {tool:"funding-rates",calls:100}.
• list_products — List high-frequency hashing/encoding/JWT/JSON utilities, live funding-rate market data, web extraction, agent-security, purchase-control, x402 and bounty-intelligence products with prices and direct paid endpoints. Example: call list_products with {} before selecting a product.
• paid_agent_purchase_firewall — Evaluate a proposed agent purchase for hard-budget, duplicate-payment, seller/payTo drift and purchase-safety conditions before execution. Native MCP x402. Use get_product_proof for the current exact input schema.
• paid_funding_loop — Screen fresh external funded tasks for payout rail, escrow, deadline and zero-deposit conditions. Native x402 payment, no API key. Example: {input:{limit:20,rail:'base'}}.
• paid_funding_rates — Fetch normalized live perpetual-futures funding rates with venue fallback and market context. Native x402 payment, no API key. Example: {input:{symbol:'BTCUSDT',providers:['binance','bybit']}}.
• paid_json_contract_check — Validate structured JSON against the supported deterministic JSON Schema subset and return exact error pointers. Native x402 payment. Example: {input:{value:{price:25},schema:{type:'object',required:['price'],properties:{price:{type:'number'}}}}}.
• paid_web_extract — Extract one public HTML page into clean Markdown, text, links, metadata and source hashes. Native x402 payment, no API key. Example: {input:{url:'https://example.com'}}.

• quote_autonomous_purchase — Given an agent goal and hard USD budget, return a buyer-controlled value ladder: cheapest relevant proof, recommended value, optional higher-outcome upgrade, and executable purchase plan. This tool itself is free and never spends funds. Example: {goal:'extract a public webpage',max_price_usd:0.01,preferred_rail:'x402'}.
• quote_instant_work — Zero-cost deterministic computation of the actual buyer-submitted reconciliation or quality task. Returns output SHA-256 and readiness; never returns the paid full result or spends USDC. Example: {input:{task:'quality',required:['id'],records:[{id:'A'}]}}.
• recommend_paid_tool — Given an autonomous-agent goal, choose the most relevant Bounty Engineer x402 product before the buyer spends money. Example: {goal:'verify an x402 seller before paying'}.
