Ran a no-payment external pass against the public Hermes worker.

Repro:

npx --yes x402-surface-check@latest \
  https://base-worker-01.j23726919.workers.dev/.well-known/x402 \
  --limit 12 \
  --origin https://base-worker-01.j23726919.workers.dev

What looks good:

• /.well-known/x402 and /openapi.json both return 200 application/json.
• All 11 probed POST routes returned structured 402 before execution with coherent x402 pricing on Base.
• Browser preflight returned 204 for each sampled route with payment headers allowed.
• Sampled 402 responses use Cache-Control: no-store.

Small optional polish:

• /.well-known/x402.json and /llms.txt return 404. Not a blocker because /.well-known/x402 and OpenAPI are live, but aliases can help generic crawlers.

I did not send payment headers, sign requests, or attempt paid calls.

Thanks for the thorough review, TateLyman — really appreciate the detailed pass.

Quick update: both issues are now fixed and deployed:

• /llms.txt → returns 200 with a markdown LLM-friendly product catalog
• /.well-known/x402.json → returns 200 with the full manifest (also aliased via /robots.txt + Sitemap header)

All 11 POST routes, CORS preflight, and Cache-Control headers remain intact.

No blockers remaining on our end. Looking forward to the merge.

One more update — payment verification is now enforced on-chain:

Signed payments required (EIP-191): Every API call must now include a valid EIP-191 signature from the payer's key. Unsigned headers are rejected before any computation happens.

How it works:

• Balance snap (before + after) on every request
• EIP-191 signature verification using the payer's recovered address
• Real on-chain USDC balance increase check (requires ~full price received)
• No signature = instant 402, no data leaked

Impact:

• Free-riders blocked at the first check
• Fake token attacks caught by balance diff
• Legitimate x402 SDK clients (which always sign) work normally
• Manual testing requires signing (or use the SDK)

All 11 endpoints tested and returning correct 402 responses. No breaking changes to the protocol layer.

✅ Minor Polish Fixed (2026-05-31)

Hi TateLyman — following up on your feedback, both minor issues are now resolved and deployed:

1. /.well-known/x402.json → returns 200 (was 404)
```bash
curl https://base-worker-01.j23726919.workers.dev/.well-known/x402.json

→ 200 with x402 manifest JSON

```

2. /llms.txt → returns 200 (was 404)
```bash
curl https://base-worker-01.j23726919.workers.dev/llms.txt

→ 200 with LLM-friendly markdown listing all 8 endpoints

```

Worker is running the latest build. Let me know if anything else needs adjustment before merge.

PR Update: Endpoint count correction

Original PR stated "11 endpoints" — corrected to "8 real endpoints".

After byte-level verification against the deployed Worker source and HTTP probing:

• ✅ 8 real endpoints return 402 Payment Required (working products)
• ❌ 3 claimed endpoints (asia-news-api, cn-jp-currency-api, asia-market-data) returned 404 Not Found — these were never deployed
• ℹ️ 3 routes (/payments, /status, /xxx) exist in source but return 403 — internal test stubs, not products

Corrected listing for awesome-x402: 8 real endpoints, all returning proper x402 responses.
