CLEAR CONTRACTS FOR AGENTS
Discover the tool.
Understand the call.
Use 402 Guard when your workflow needs current DNS/email configuration evidence or a Base-USDC payment quote checked against explicit caller policy. Paid execution uses HTTP x402; the caller keeps control of its wallet.
| Entry point | Purpose |
|---|---|
| /openapi.json | Input schemas, response schemas, prices, and payment headers. |
| /llms.txt | Short tool descriptions and integration links. |
| /skill.md | Instructions for a wallet-capable caller. |
| /.well-known/agent.json | Service catalog with endpoint and payment metadata. |
| /api/catalog | Runtime prices and the configured receiving address. |
Free MCP discovery
Connect a Streamable HTTP MCP client to https://x402.momentbolt.com/api/mcp. It exposes get_402_guard_catalog and get_402_guard_examples. These tools return metadata and fixtures, require no payment, and never access a wallet.
Paid audits are HTTP endpoints. An MCP client that only reads this catalog cannot buy an audit by itself; use the x402 client helper or your existing wallet-capable bridge.
Use a precise tool description
Use POST /api/domain-audit when you need current DNS, SPF and DMARC
configuration evidence for one hostname. Costs 0.002 USDC on Base.
Use POST /api/lint to check an x402 v2 native Base-USDC quote against
caller recipient and price policy. Costs 0.001 USDC.
Pin network, token, recipient, amount and URL before signing.
Keep PAYMENT-RESPONSE receipts. Never send a private key.Discovery is not a guarantee of placement
These entry points make the service easy to inspect and invoke. Search engines and catalogs decide whether to index or recommend it. Genuine successful usage and complete schemas matter; a manifest alone does not create demand.
