Validates a draft EU Deforestation Regulation Due Diligence Statement for structural correctness — required fields, HS-code/commodity consistency, EORI and ISO country formats, quantity units, per-plot geometry, and deforestation-free cut-off assertion — without checking satellite data or filing anything.
- [EU AI Act Article 50 Transparency Obligation Lookup](https://www.zero.xyz/c/eu-ai-act-article-50-transparency-obligation-lookup-b2346bd6/llms.txt): $0.04/call via x402.

- [ChainVerdict EUDR Geo-Check](https://www.zero.xyz/c/chainverdict-eudr-geo-check-1025258b/llms.txt): $0.1/call via x402. Validates EUDR plot geolocation by checking coordinate bounds, ring closure, self-intersection, area, size-to-geometry rules, and lat/lon axis ordering errors.
- [EUDR HS Code Scope Checker](https://www.zero.xyz/c/eudr-hs-code-scope-checker-f4c221f0/llms.txt): $0.02/call via x402. Determines whether a given HS code falls within the EU Deforestation Regulation scope, returning the regulated commodity and applicable enforcement deadline tier.
- [CBAM De Minimis Threshold Tracker](https://www.zero.xyz/c/cbam-de-minimis-threshold-tracker-73749a27/llms.txt): $0.05/call via x402. Tracks a year's worth of import lines against the CBAM 50-tonne de minimis threshold and flags the retroactivity trap, where crossing the threshold pulls all in-scope imports for that year into scope, while correctly excluding electricity and hydrogen from the count.
- [CBAM Annual Declaration Pre-Submission Structural Checker](https://www.zero.xyz/c/cbam-annual-declaration-pre-submission-structural-checker-19ceca4c/llms.txt): $1/call via x402. Performs a structural pre-submission check of a draft CBAM annual declaration, verifying required fields, per-good completeness, CN scope, ISO country formats, EU-origin contradictions, reporting-year plausibility, and de minimis cross-checks.
- [C2PA Manifest Structural Checker](https://www.zero.xyz/c/c2pa-manifest-structural-checker-23f59680/llms.txt): $0.04/call via x402. Performs a structural analysis of a C2PA content-credential manifest, checking claim generator, assertions, c2pa.actions history, digitalSourceType for AI-trained media declarations, and signing status — without verifying the signature or certificate chain.
- [RegRails CBAM Embedded Emissions & Certificate Cost Estimator](https://www.zero.xyz/c/regrails-cbam-embedded-emissions-certificate-cost-estimator-4f42f9fb/llms.txt): $0.25/call via x402. Computes line-by-line embedded emissions and indicative CBAM certificate costs for imported goods, echoing every arithmetic step, using caller-supplied emission factors and certificate prices.
