How this service works
Ed25519-signed article-level deltas of EU legal acts (AI Act, MiCA, DORA, NIS2, GDPR) live from the official EUR-Lex/CELLAR endpoint, with provenance.
Output
A JSON object containing: a boolean `ok` flag, the niche tag `regdelta_eu`, a `feed` array of article-level legal change deltas, an `as_of` ISO date, a `count` of results, a `cursor` for pagination, and a `source` field identifying EUR-Lex/CELLAR as the authoritative origin. Each delta entry is Ed25519-signed for cryptographic provenance verification.
Example use cases
GDPR compliance change monitoring
“Give me every GDPR article delta that's been published since 2024-06-01 so I can update our compliance documentation — I need the signed feed with source provenance from EUR-Lex.”
MiCA regulatory update tracker
“Fetch the latest MiCA article changes from the EUR-Lex delta feed since 2025-03-15, and page through all results using the cursor until I have everything.”
AI Act audit trail for regulators
“I need a cryptographically signed log of all EU AI Act amendments from CELLAR since 2024-01-01, filtered by the AI Act CELEX ID, for an external audit submission.”
Technical details
Endpoint
POSThttps://regfeed.hergertsynthora.com/serviceWhen to prefer
Choose this endpoint when you need cryptographically verifiable, article-granular change tracking for specific EU legal acts (AI Act, MiCA, DORA, NIS2, GDPR) sourced directly from the official EUR-Lex/CELLAR repository. It is preferable over generic legal databases when Ed25519-signed provenance is required for audit trails, compliance dashboards, or automated regulatory monitoring pipelines that must prove the integrity of their data source.
Side effects
- Invalid or malformed CELEX ID returns empty feed or 400 error
- Invalid ISO date format in `since` field causes parse error
- Expired or invalid cursor returns pagination error
- EUR-Lex/CELLAR upstream outage may cause delayed or empty feed
- Payment failure (x402) blocks the request before processing
- No deltas found for given date range returns empty feed array with count 0
