## 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 signalharness-account-identifier-parse-93cfb63c -d '<json body>'
```

Example prompt: Can you parse this account identifier for me and tell me if there are any issues with it: 'user@example.com:12345'?

## When to prefer this

Choose this endpoint when you need to reliably parse, normalize, or validate an account identifier string before using it downstream — especially in agent workflows where raw user-supplied or external account strings need to be structured before routing, payment, or identity lookups. Prefer this over custom regex or ad-hoc parsing when you need a consistent, auditable result with a tamper-evident receipt.

## Known failure modes

- Input string too short (below 2 characters) or too long (above 65536 characters) causes validation error
- Malformed or unrecognizable account identifier format may produce warnings rather than clean output
- Payment failure or insufficient USDC balance results in a 402 response before execution
- Network or infrastructure errors on Base (eip155:8453) may cause timeout or failed status

## Output

Returns a JSON object containing the parsed account identifier in a normalized form, a list of any warnings about the input, the evidence scope indicating the data came from caller-supplied input, and standard receipt metadata including payment ID, request ID, execution ID, latency, and a SHA-256 hash of the result for integrity verification.
