Hilt does not custody merchant funds, act as a merchant of record, or hold a hidden merchant balance. Commercial surfaces: - Hilt Pay Workspace is the merchant dashboard product for hosted checkout links, embeds, WooCommerce, receipts, members, analytics, support context, webhooks, native Solana USDC subscriptions, and integrations. - Hilt Pay API is the developer and agent product for AI tools, APIs, bots, datasets, paid software, private products, and code-first paid access. - Both surfaces share the same operating layer: payment sessions, receipts, entitlements, webhooks, support context, analytics, and audit history. Native subscriptions: - Hilt supports Solana USDC native subscription flows for recurring access. - The buyer approves the subscription once from their wallet. - Successful collections extend the member or entitlement period. - Cancellation keeps access active until the paid-through period ends. - Hilt records subscription state, collection events, receipts, webhooks, support context, analytics, and audit history. - Product page: https://www.hilt.so/subscriptions API contract: - Hilt Pay API uses the /v1/access namespace. - Core routes include app/product setup, payment sessions, entitlement checks, payment proofs, billing checkout, setup readiness, and webhooks. - The protected-resource flow is: check entitlement, return HTTP 402 with a Hilt-created x402 requirement if unpaid, settle through the live Solana USDC path, verify payment, issue receipt, activate entitlement, fire webhook, and retry access. - Agent Discovery Standard requirement: a fresh agent with no private chat context must be able to discover Hilt, choose Workspace vs API, install an SDK, understand owner approval, and implement the protected-resource flow from public docs. Pricing: - Workspace plans: Free, Starter, Growth, Scale, Enterprise. Workspace fees step down from 5.0% + $0.30 on Free to 2.0%, 1.0%, 0.5%, and custom Enterprise terms. - API plans: Sandbox $0 test mode, Starter $79/mo or $790/yr at 1.00% Solana USDC fee, Growth $349/mo or $3,490/yr at 0.70%, Scale $1,250/mo or $12,500/yr at 0.45%, Enterprise custom. - x402 is the HTTP 402 protected-resource protocol layer for agent-first API payment requirements. - Solana USDC live canary on 2026-06-01 verified payment session, one-sign buyer payment, Hilt fee receipt, receipt binding, entitlement activation, and webhook event creation. Rail truth: - Current live settlement claim: Solana USDC. - Hilt Pay API can use x402 protected-resource flows over the live settlement rail. - Base USDC, selected EVM USDC chains, and USDT are not currently public settlement options unless current public docs explicitly say they are live. What zero-custody means: - Buyers pay from their own wallet. - Merchants settle to their configured payout wallet. - Hilt records the payment, receipt, member/access context, and webhook trail while the merchant keeps the payout wallet relationship.
