Hilt lets APIs, AI agents, and merchants charge for access via HTTP 402 and Solana USDC settlement — payment, receipts, and entitlements in one request.
Hilt is a payment-to-access platform built around the HTTP 402 ("Payment Required") status code and its emerging x402 protocol, letting APIs, AI agents, and digital merchants gate access behind a stablecoin payment that settles instantly on Solana in USDC. Rather than treating payment as a separate step before or after the real request, Hilt positions the payment inside the request itself: a buyer pays from their own wallet, Hilt records the on-chain settlement, and access (an API call, a Telegram/Discord membership, a private download, a subscription) is granted atomically once payment clears. The company describes this as a zero-custody model — Hilt does not hold merchant funds first, the merchant's own payout wallet is the settlement destination.
Beyond raw API/agent payments, Hilt ships several ready-made commerce surfaces: a WooCommerce plugin that adds wallet-native USDC checkout to WordPress stores, hosted checkout links for one-off digital products and paid communities, native Solana USDC subscriptions for recurring access, and turnkey flows for selling paid Telegram and Discord memberships. A merchant dashboard provides analytics, buy notifications, member/customer records, and CSV/PDF exports. On the developer side, Hilt provides an x402-compliant reference implementation (published on GitHub) so AI agents and API providers can accept agent-to-agent micropayments without manually building settlement, receipts, and entitlement logic. Hilt states it has been approved for the Alchemy Solana Fund.
Key Features
x402 protocol payments — Standardized HTTP 402 implementation letting APIs and AI agents require payment before granting access, with settlement handled in the same request.
Solana USDC settlement — Buyers pay from their own wallet and funds settle directly on Solana in USDC to the merchant's payout wallet, without Hilt holding custody first.
WooCommerce checkout — A WordPress plugin adding wallet-native USDC checkout as a payment option on WooCommerce stores.
Telegram & Discord memberships — Turnkey flows for selling paid access to Telegram and Discord communities.
Native subscriptions — Recurring Solana USDC subscriptions for ongoing paid access, without requiring stored-card autopay.
Merchant dashboard — Analytics, buy notifications, member/customer records, and CSV/PDF exports for tracking sales.
Pros & Cons
Pros
Zero-custody settlement model — buyer funds go to the merchant's own payout wallet rather than sitting with Hilt first.
Built around the emerging HTTP 402 / x402 protocol, positioning Hilt early for agent-to-agent and API-metered payments.
Transaction fees scale down (5% on the free plan to as low as 0.1% on Enterprise) as merchants move to higher tiers.
Multiple ready-made commerce surfaces beyond raw API integration — WooCommerce plugin, Telegram/Discord memberships, hosted checkout links, and native subscriptions.
Cons
Settlement is limited to Solana USDC, so merchants and buyers need a compatible crypto wallet rather than being able to use traditional cards.
As an early-stage stablecoin payments product, public information on company history, team, and funding beyond an Alchemy Solana Fund mention is limited.
The free plan carries the highest transaction fee (5% + $0.30), so costs only become competitive once a merchant upgrades to a paid tier.
