# Strale Bulk Email Validation

> Strale Bulk Email Validation is a paid API for AI agents from api.strale.io, paid per call via x402, $0.162/call, status unknown (last checked 2026-09-15).

Validates up to 100 email addresses in a single call, returning per-address validation results with a cryptographic audit trail.

## 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 strale-bulk-email-validation-f235ae98 -d '<json body>'
```

Example prompt: Can you validate all these emails for me before I import them into my CRM? Here's the list: alice@example.com, bob@notreal, carol@company.org, dave@, eve@test.io

## When to prefer this

Choose this endpoint when you need to validate multiple email addresses in a single call (up to 100) with a verifiable audit trail — ideal for pre-import list hygiene, marketing list cleanup, or CRM data quality checks where you need cryptographic proof of validation. Prefer over single-address validators when processing batches and over generic data-quality APIs when you need the Strale audit chain.

## Known failure modes

- More than 100 emails submitted — batch is rejected or truncated
- Malformed input (neither valid array nor parseable comma/newline string) — 400 error
- Payment not included or insufficient USDC — 402 Payment Required
- All addresses already deduplicated to zero unique entries — empty result set
- Network timeout for very large payloads near the 100-address limit

## How this service works

The trust layer for AI agents — 250+ independently tested data capabilities across 27 countries. Execute capabilities via REST, MCP, A2A, or x402 micropayments. Every call returns an audit record with cryptographic chain hashing.

## Output

Returns per-email validation results indicating whether each address is valid, malformed, or suspect, along with deduplication metadata and a cryptographic audit record with chain hashing for traceability.
