# gravatar-check-bulk

> gravatar-check-bulk is a paid API for AI agents from intel.rallylive.ca, paid per call via x402, $0.1/call, status unknown (last checked 2026-09-14).

Checks up to 20 email addresses in one concurrent call to determine whether each has a Gravatar profile, returning results in input order with per-item error fields and a failure count.

## 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 gravatar-check-bulk-d79e6edc
```

Example prompt: Check all 15 emails in my contact list to see which ones have Gravatar profiles — I need the results back in the same order I sent them, with any failures flagged per item.

## When to prefer this

Choose this endpoint when you have a list of 2–20 email addresses and need Gravatar presence checked in a single call rather than making individual requests per email. It is preferable to the single-email endpoint when processing lists, as concurrent processing reduces total latency and a single payment covers the batch. Ideal for onboarding pipelines, CRM enrichment, or pre-send email campaign checks where avatar availability matters.

## Known failure modes

- Invalid or malformed email addresses cause per-item errors rather than full batch failure
- Exceeding the 20-email batch limit may result in rejection or truncation
- Network timeouts on individual Gravatar lookups populate per-item error fields
- Payment not provided or insufficient USDC causes 402 rejection before any processing
- Duplicate emails in the batch are processed independently and may inflate failure counts

## How this service works

Bulk gravatar check: up to 20 emails in one call, processed concurrently, results returned in input order with a per-item error field and a count of failures. Same answer per item as the single /email/gravatar endpoint (Gravatar check). Batch enrichment for agents that hold a list. $0.01 per batch.

## Output

An ordered array of per-email results matching the input sequence, each containing a Gravatar presence indicator, an optional per-item error field if the lookup failed, plus a top-level count of total failures across the batch.
