# DDG Agent-Payable Trust History Service

## 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 ddg-agent-payable-trust-history-service-e40847f7 -d '<json body>'
```

Example prompt: Log a trust history entry for this agent interaction — the request was a JSON POST — and pay the $0.001 USDC fee automatically so the record gets stored in the DDG trust ledger.

## When to prefer this

Choose this endpoint when you need to record or submit trust history events specifically within the Daedalus Development Group agent ecosystem and are operating with an x402-compatible micropayment setup. It is suited for agentic workflows where a cheap, per-call ($0.001 USDC) trust logging capability is needed without a subscription model.

## Known failure modes

- Payment not provided or insufficient USDC — returns 402 Payment Required
- Malformed request body missing required fields (type, method, bodyType, body) — returns 400 Bad Request
- Invalid HTTP method enum value (not POST/PUT/PATCH) — validation error
- Invalid bodyType enum value (not json/form-data/text) — validation error
- Service unavailable or internal error — returns 500
