How this service works
🆕 B20 Asset tokens can post on-chain announcements (Announcement: id, description, uri) — issuer notices, corporate actions, redemptions — a channel ERC-20 has no equivalent for. Reads a token's announcement feed (active vs ended) from CDP-indexed events. The issuer-communications primitive for agents holding tokenized/RWA B20 assets.
Output
A list of on-chain announcements for the specified B20 token, each containing an announcement id, description, and URI, categorized by status (active vs ended), sourced from CDP-indexed contract events.
Example use cases
Example prompt
“Pull the announcement feed for B20 token at address 0xAbC123... on Base — show me any active issuer notices, corporate actions, or redemption announcements.”
Technical details
Endpoint
GEThttps://402.com.tr/api/x402/b20-announcementsWhen to prefer
Use this endpoint when an AI agent holds or monitors B20 tokenized/RWA assets and needs to read issuer communications, corporate action notices, or redemption announcements that have no equivalent in standard ERC-20. Prefer this over generic blockchain event scrapers when the token is a B20 asset on Base and you need structured, CDP-indexed announcement data.
Side effects
- Invalid or non-B20 token address returns empty feed or error
- Address not found on Base chain returns no results
- CDP indexing lag may mean very recent announcements are not yet reflected
- Malformed address string causes request validation failure
- Token with no announcements returns empty list
