# SPF Record Check Bulk

> SPF Record 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 SPF DNS records for up to 20 domains concurrently in a single call, returning per-domain results with 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 spf-record-check-bulk-ff34c12a
```

Example prompt: Can you check the SPF records for all these domains at once: example.com, acme.org, testco.io, and 5 others from my list — I need to know which ones have SPF configured correctly and which are failing?

## When to prefer this

Choose this endpoint when you have 2–20 domains to check and want to minimize API calls and latency by processing them concurrently. Use the single /email/spf endpoint instead when checking only one domain. Prefer this over sequential single-domain calls whenever you have a list, as it processes all items concurrently and returns results in input order with structured per-item errors.

## Known failure modes

- More than 20 domains submitted — batch limit exceeded
- Invalid domain name format in input list causes per-item error
- DNS lookup timeout for a domain results in per-item error with failure counted
- Domain has no SPF record — returned as a result with appropriate empty/null SPF field and possible error flag
- Network issues reaching DNS resolvers cause partial or full batch failure

## How this service works

Bulk spf record check: up to 20 domains 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/spf endpoint (SPF record check for a domain). Batch enrichment for agents that hold a list. $0.01 per batch.

## Output

An ordered array of per-domain results matching the input order, each containing the SPF record data (same as the single /email/spf endpoint), a per-item error field indicating any lookup failures, and an overall count of failed items across the batch.
