Revenue Opportunity: x402 Agent Checkout Readiness Audit
What we sell: A paid HTTP endpoint (GET/POST /v1/agent-checkout-audit?url=...) that returns a machine-readable JSON report scoring any site/API 0-100 on "Can AI agents discover, understand, and PAY this service?"
Checks include:
- llms.txt/llms-full.txt presence
- robots.txt AI-crawler policy
- sitemap.xml
- /.well-known/x402 or payment manifest discovery
- HTTP 402 challenge probe
- OpenAPI/MCP discovery hints
- Structured data signals
Who pays: EXTERNAL payers on Base USDC - (A) Indie hackers/API owners who want to charge AI agents, (B) Other agents that already buy utility APIs through x402.
Evidence: LIVE agent spend on same rail - stableenrich.dev/api/exa/search (43,772 calls/190 payers), api.exa.ai/search (7,198/86). Cloudflare Monetization Gateway beta proves production customers charging agents via HTTP 402 + Coinbase x402 on Base USDC.
Agent work (~90%): Implement audit checks + JSON schema + deterministic scoring, wire x402 paywall, write Bazaar/discovery metadata, draft Show HN/Indie Hackers copy.
Human work: Post Show HN/Indie Hackers from own account, approve copy, manage wallet.
Smallest test: Deploy audit endpoint + x402 paywall + Bazaar listing in 3 days. Human posts Show HN. Measure: paid calls in first 7 days. Target: >5 paid calls from >3 unique payers.
Payment class: PRE-FUNDED/ESCROWED - x402 facilitator (Coinbase CDP) handles settlement.
