## 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 prysm-abstract-email-lookup-56ebbf76 -d '<json body>'
```

Example prompt: Can you look up the email address john.doe@acme.com using Abstract Email and tell me if it's valid, deliverable, and whether it's from a disposable or free provider?

## When to prefer this

Choose this endpoint when you need a quick, pay-per-call email validation without managing Abstract API credentials yourself — ideal for agents making occasional lookups via x402 micropayments on Base in USDC. Prefer it over direct Abstract API calls when you want a single credentialed gateway that handles billing automatically.

## Known failure modes

- Invalid or malformed email input returns a validation error
- Unrecognized operation name returns an allowlist error
- Upstream Abstract API timeout returns a 504 or partial response
- Payment not settled via x402 returns a 402 Payment Required response
- Rate limiting by the underlying provider may return a 429

## How this service works

Prysm sells paid, agent-ready provider capabilities over x402 on Base mainnet using USDC.

## Output

Returns a JSON object with email validation details including deliverability status, format validity, SMTP check results, whether the domain is free or disposable, MX record presence, and a quality/risk score for the email address.
