Website release evidence and offline tools, under one Agent402 catalog.

Three featured products live under this umbrella: a 5-USDC AI Discovery Site Audit, a 5.99-USDC printable fantasy quest-card deck, and a 5.99-USDC bulk QR campaign pack. Their separate methods, prices, and delivery formats are explicit below; four auxiliary developer resources remain available in the same catalog.

The umbrella exposes three featured contracts: POST /site-release-audit for 5.00 USDC, GET /download for 5.99 USDC, and GET /qr-campaign-pack for 5.99 USDC. Read /openapi.json and /.well-known/x402 before choosing one; four auxiliary resources remain discoverable.

Direct HTTP Resources

Seven stable resource URLs expose bounded request and response contracts without a gateway session.

Usage-Based Spend

Per-resource pricing is explicit in the OpenAPI contract, x402 manifest, and each unpaid 402 challenge.

Machine Discoverable

Canonical machine surfaces are stable and public: /openapi.json, /.well-known/x402, and /meta.json.

Contract First

Read /openapi.json for schemas, then confirm authoritative payment terms in /.well-known/x402.

Direct HTTP Lifecycle

Select a resource, send its documented HTTP request, handle a 402 challenge, and retry the identical request with proof.

402-Aware Calls

On paid calls, handle 402 Payment Required, settle x402, and retry with proof without changing arguments.

Why Direct HTTP

Human mode is optimized for product and infra decisions. Each paid product has its own stable HTTP contract and exact Base-USDC terms.

Seven direct resources instead of a session-oriented gateway.
Explicit x402 billing semantics for every paid operation.
OpenAPI and x402 v2 metadata for agents, API clients, and indexers.
Stable URLs plus all-time settlement proof at /metrics.

Direct Call Flow

GET /openapi.json for direct request and response schemas.
GET /.well-known/x402 for resource URLs, prices, network, asset, and payee.
Call the selected resource with its documented method and input.
On 402 Payment Required, complete payment and retry the identical request with proof.

curl -sS https://agent402.dev/openapi.json
curl -sS https://agent402.dev/.well-known/x402
curl -sS https://agent402.dev/health

Core Direct Paths

For robust clients, cache and refresh /openapi.json and /.well-known/x402; use /metrics for independently inspectable settlement history.

Agent Quickstart

This mode is concise and protocol-oriented. Use this exact order: /openapi.json -> /.well-known/x402 -> direct resource URL.

Read method and schemas from the OpenAPI contract.
Confirm price, network, asset, and payee from the x402 manifest.
Call the direct resource URL.
If 402 is returned, pay and retry the identical HTTP request.

OpenAPI 3.1: https://agent402.dev/openapi.json
x402 resource manifest: https://agent402.dev/.well-known/x402
Settlement metrics: https://agent402.dev/metrics
Health: https://agent402.dev/health

Direct HTTP Flow

# 1) Confirm the URL is eligible for the audit (free)
curl -sS -X POST https://agent402.dev/site-release-audit/eligibility -H 'content-type: application/json' -d '{"url":"https://example.com/"}'

# 2) Read product metadata and authoritative x402 payment terms
curl -sS https://agent402.dev/api/product
curl -sS https://agent402.dev/.well-known/x402

# 3) Call the audit without payment to receive its 5-USDC challenge
curl -i -X POST https://agent402.dev/site-release-audit -H 'content-type: application/json' -d '{"url":"https://example.com/"}'

# 4) Settle the exact Base-USDC terms, then retry the identical request
#    with the PAYMENT-SIGNATURE header.

402 Retry Flow

If a standalone resource returns HTTP 402:
1) Read x402 payment requirements from response.
2) Pay requested amount to requested pay target.
3) Retry the same HTTP request with x402 payment proof.

Do not mutate method, URL, body, or arguments between attempt #1 and paid retry.
