Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00040 | $0.01571 |
| Opus 5.5 | $0.00016 | $0.00628 |
| Sonnet 5.5 | $0.00008 | $0.00314 |
| Haiku 4.5 | $0.00004 | $0.00157 |
Grade A, and why
scvd-x402-verification scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 19d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Makes network callslowCapability
Not a fault in itself. Listed so you know the mod talks to something, and to what.
curl --fail-with-body https://scvd.store/api/preflight/v2 \ This is a copy
100% identical to scvd-x402-verification — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 140 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Checking an x402 door before and after you pay
Use SCVD before paying an unfamiliar x402 endpoint, to check a signed receipt from any issuer, or when a recipient needs a durable independent observation. SCVD observes and signs; it does not guarantee delivery, resolve disputes, or rate vendors.
Nothing from this store can act without your decision. Never provide credentials, private keys, seed phrases, or wallet secrets.
Connect and start free
Connect a remote MCP client to https://scvd.store/mcp; read tools/list
for the current schemas. The full store guide is at read_store_guide.
This focused skill is also installable from its public GitHub source:
npx skills add seancrecord/scvd-general-store-repo --skill scvd-x402-verification
A missing marketplace listing is not proof that the source or service is missing. Without MCP, use the public HTTP preflight directly:
curl --fail-with-body https://scvd.store/api/preflight/v2 \
-H 'Content-Type: application/json' \
--data '{"url":"https://merchant.example/paid-endpoint"}'
Replace the example with the exact endpoint under consideration.
preflight_endpoint is the free MCP instrument; read its returned battery
version rather than assuming it selected HTTP v2.
Decide from the reading, not the label
- Preflight is unsigned and unpaid. Read
verdict,reached_level, the individual checks, advisories, method and stated gaps.readymeans the checks reached passed. It does not prove a payment can settle, goods will arrive, the merchant is reliable, or that you may spend. - An inconclusive probe is inconclusive. A timeout, method refusal or unreachable result does not establish fraud or permanent absence. Do not pay through a failed applicable check. Resolve the failure or stop.
- Keep coverage distinct from absence. No report in hand, no matching
listing, or a
never_methistory result means that this lookup did not supply evidence. It does not prove that no evidence trail exists. - After an authorized purchase, inspect the merchant's receipt.
check_conformanceis free and accepts any issuer's signed offers or receipts. Its findings concern that artifact; a seller's signature is not an independent SCVD observation of delivery.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
