Add CryptoGuard to x402 ecosystem (Services/Endpoints)

[gpartin]

CryptoGuard - Per-transaction crypto trade validator powered by WaveGuard physics engine. One API call before every trade: resolves token, runs anomaly detection via wave-equation PDEs (no ML), checks rug pull risk, cross-references CEX/DEX pricing, and returns a deterministic PROCEED / CAUTION / BLOCK verdict.

Endpoints:

• POST /v1/validate-trade - Primary: one call, one verdict, every trade vetted
• POST /v1/validate-trades - Batch up to 20 trades
• GET /v1/scan/{coin_id} - Single token anomaly scan
• POST /v1/portfolio/scan - Portfolio batch (up to 50 tokens)
• GET /v1/scan/{coin_id}/history - Historical self-comparison
• GET /v1/rug-check/{chain}/{pair} - Rug pull risk assessment
• GET /v1/dex/new-pairs - New DEX pair discovery

Pricing: 0.05 USDC/scan on Base

The field ordering in this metadata.json file doesn't follow the newer convention used by recent partner additions. Many recent partners place the "category" field immediately after "name" (line 2-3 position), rather than at the end. While both orderings work functionally, following the more recent pattern would improve consistency. Consider reordering the fields as: name, category, logoUrl, description, websiteUrl.

please sign your commit and tag me to review again
also just a heads up /v1/dex/new-pairs seems to be free

[gpartin]

Thanks for the review @Must-be-Ash!

Signed commits: Done latest commit is GPG-signed.

/v1/dex/new-pairs appearing free: This is by design. CryptoGuard has a 5 free calls/day/IP tier to let developers evaluate the API before committing to x402 payments. After the 5th call from the same IP in a 24-hour window, the endpoint enforces x402 payment (.05 USDC on Base). The free tier logic is in _check_free_tier() it tracks call counts per IP per day and only calls _check_x402_payment() once the limit is exceeded.

So the data you saw was real you just hit it within the free window. The x402 paywall is fully wired and active beyond that threshold.

Hey @Must-be-Ash — just checking in on this. Commits are signed and metadata is reordered per your feedback from Feb 26. Let me know if anything else is needed for review. Thanks!

[Must-be-Ash]

hi there, you still have an unsigned commit. All commits must have verified signatures.

Fixed! Squashed into a single signed commit (d279694). All commits now have verified signatures. Thanks for catching that!

[gpartin]

Superseded by #1888 which consolidates both WaveGuard and CryptoGuard into a single PR and uses the correct field ordering (name, category, logoUrl, description, websiteUrl) per the convention suggested in the review.
