## 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 delx-commerce-dns-spf-record-parse-6b281702 -d '<json body>'
```

Example prompt: Parse this SPF record for me and tell me what mechanisms it includes and what the terminal directive is: 'v=spf1 include:_spf.example.com ip4:192.0.2.0/24 -all'

## When to prefer this

Choose this endpoint when you need fast, in-memory, no-retention parsing of a raw SPF record string into structured data. It is ideal for agents performing email infrastructure audits, validating SPF syntax, or counting DNS lookup terms without needing to do a live DNS query. At $0.001 per call with no signup, it suits high-frequency automated checks. Prefer it over general-purpose parsing libraries when you need a verified, schema-versioned result with an input hash for auditability.

## Known failure modes

- Malformed or empty SPF record string may return a parse error or unexpected mechanism list
- Records exceeding 8192 characters will be rejected by input validation
- Non-SPF TXT records passed as input may produce empty or nonsensical mechanism lists
- Records with circular include chains cannot be fully resolved at parse time (only the literal string is parsed)

## How this service works

Pay-per-result APIs for agents. No signup. Exact price. Verifiable delivery. USDC on Base + Solana via x402.

## Output

Returns a JSON object containing a list of parsed SPF mechanisms (e.g. include: directives, ip4/ip6 ranges, terminal directive), the terminal policy string (e.g. '-all', '~all'), and a count of DNS lookup terms used. Also includes schema version, operation name, and evidence metadata (input SHA256, retained=false, external_calls count).
