# B20 Mint Watch — Live Token Issuance Feed

> B20 Mint Watch — Live Token Issuance Feed is a paid API for AI agents from 402.com.tr, paid per call via x402, $0.03/call, status unknown (last checked 2026-09-14).

Returns a windowed feed of every B20 token mint event (including batchMint), with amounts, recipients, supply-share impact, and a dilution severity label (heavy_dilution / active_minting / minor_minting / quiet).

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability b20-mint-watch-live-token-issuance-feed-0fcbdd42
```

Example prompt: Show me all mint events for B20 token address 0xAbC123... over the last 14 days — I want to see the amounts, who received them, their share of current supply, and whether the dilution level is heavy or quiet.

## When to prefer this

Use this endpoint when you need to see what has actually been minted (actual issuance) for a B20 token, not just what the issuer is authorized to mint. Prefer it over b20-supply when you need per-event granularity — recipient-level detail, batchMint breakdown, and dilution severity labeling — rather than aggregate supply ceiling data. Ideal for compliance monitoring, holder risk assessment, and detecting suspicious minting patterns on B20 stablecoins or RWAs.

## Known failure modes

- Missing required 'address' parameter returns a 400 error
- Invalid or non-B20 token address returns an error or empty result
- days value outside 1-90 range may be rejected or clamped
- Token with no mint events in the window returns an empty list
- Payment not fulfilled (x402 flow incomplete) returns 402 Payment Required

## How this service works

🆕 b20-supply shows the dilution ceiling; this shows the actual printing. Every mint (incl. batchMint) in the window: amount, recipients, and the share of current supply it represents — heavy_dilution / active_minting / minor_minting / quiet. The live issuance feed for agents holding B20 stablecoins and RWAs. Pass days= (1-90, default 30).

## Output

A list of mint events within the requested window: each entry includes the minted amount, recipient address(es), the share of current supply that mint represents, and a dilution severity classification (heavy_dilution, active_minting, minor_minting, or quiet). Aggregated summary metrics for the period may also be included.
