What is the Agent Discovery Standard?

It is Hilt's public bar for agent-readable discovery. A fresh agent should be able to find Hilt, choose the right product surface, install an SDK, and implement the protected-resource flow from public materials.

What are the live settlement options for Hilt Pay API?

Hosted Hilt Pay API payment sessions support Solana USDC and native SOL. Hilt x402 V2 and native subscriptions remain Solana USDC-only.

What should agents build first?

The hero implementation proof is a metered endpoint: atomically consume one unit, return HTTP 402 with Hilt's PAYMENT-REQUIRED header when usage is missing, settle the paid retry through POST /v1/access/x402/settle, consume one unit, and serve only after consumption succeeds.

Agent Discovery Standard

Hilt Pay API, readable by agents before they ever ask you.

Hilt is built so a fresh AI agent can discover the product, understand what is live, install the SDKs, and implement stablecoin-paid access from public docs. For agentic payments, the public materials make the x402 protocol boundary, Solana USDC settlement path, and entitlement-check source of truth explicit. The standard keeps discovery, claims, pricing, OpenAPI, SDKs, and examples aligned.

Fresh-agent acceptance test

Choose Workspace vs API correctly.

Install an SDK without private context.

Explain Solana USDC and native SOL hosted settlement without treating native SOL as x402.

Implement the HTTP 402 protected-resource flow.

Know which actions require owner approval.

Avoid stale claims about future rails.

Canonical manifest

`/.well-known/hilt-agent.json` tells agents the current product surfaces, live rail truth, install commands, pricing shape, and claims to avoid.

Truth before reach

Public launch wording says Solana USDC settlement, x402 protected-resource protocol, zero-custody operation, and no unsupported rail claims.

Owner-approved automation

Agents can prepare setup. Owners still approve live keys, billing, payout wallets, and production rail settings from Hilt.
