Everything except a fresh validation is free. Plyrium's separate SaaS product (the contractor CRM) is tiered per month and is recorded below for completeness because it is the company's Pricing page, but it does not sell API access. plan_count: 2 plans: - id: vouchspec-fresh-validation name: VouchSpec fresh exact-commit validation (mainnet) type: usage-based audience: agents only (human_checkout false) currency: USDC network: eip155:8453 (Base mainnet) price: '0.25' atomic_amount: '250000' billing: per request, settled onchain via x402 v2 exact scheme before fulfillment facilitator: https://api.cdp.coinbase.com/platform/v2/x402 buyer_price_ceiling: max_price.amount_minor 25-1000000 USD cents supplied by the buyer in the request included: - one isolated static validation of one public GitHub Agent Skill commit - one Ed25519-signed DSSE receipt, publicly cacheable and shareable - live receipt status and issuer key, free thereafter limits: - request body 16,384 bytes - expected delivery 10 minutes - delivery capability expires after 30 days refunds: automatic remedy for objective failures only (see conventions/ reversibility) price_history: PRICING.md records that an earlier $49 Stripe-checkout hypothesis was rejected; predeclared future cohort tests at $0.10 and $0.50 are gated on adoption evidence and are NOT current prices - id: vouchspec-free-surface name: VouchSpec free surface type: free price: '0' included: - discovery, health, x402 manifest (anonymous) - A2A message/send discovery skill and MCP get_vouchspec_discovery tool (anonymous) - existing signed receipt retrieval by SHA-256 and live invalidation status (anonymous) - issuer public key - Base Sepolia sandbox at 1.00 test USDC per validation (test funds, not revenue) product_plans_not_api: note: Plyrium SaaS tiers from https://www.plyrium.com/pricing (monthly, USD, 14-day free trial, no setup fee).
