Tools of VerifyPulse: email deliverability checks
	Description		Read-only	Idempotent	Open world
`analyze_email_authentication`Free. Explain why an email passed or failed authentication or went to spam. Pass the raw message, or just its headers: checks DKIM signatures (verified when the body is included), whether the sending IP is authorized by SPF, DMARC alignment and policy, what the receiving server recorded, and delays at each relay hop. Returns the reasons in plain words.	Free. Explain why an email passed or failed authentication or went to spam.

`audit_sending_domains`Free for up to 3 domains per call. Audit several sending domains at once and get a grade, SPF lookup count, DMARC policy, DKIM status, MTA-STS (policy checked against the MX hosts), TLS-RPT, BIMI and fixes for each, plus a snapshot to pass to monitor_sending_domains later.

`check_blocklists`Free. Whether an IPv4 address, or a domain's MX and A addresses, are listed on the SpamCop and PSBL blocklists. Spamhaus and Barracuda are not queried (their terms require a subscription); the result says which lists were checked.	Free.

`domain_intel`Free. Registration data for one domain from the registry (RDAP): when it was registered and its age in days, expiry, registrar, status codes, nameservers and DNSSEC. Flags domains registered in the last 30 days, a strong spam and fraud signal, and domains about to expire.	Free.

`flatten_spf`Free. Replace the includes in a domain's SPF record with the IP ranges they resolve to, and return the TXT records to publish. Use it when an SPF record is at or over the 10-lookup limit.	Free. Replace the includes in a domain's SPF record with the IP ranges they resolve to, and return the TXT records to publish.

`get_fix_kit`Fix a domain whose email goes to spam or fails SPF, DKIM or DMARC. Returns the exact DNS records to publish (host, type, value) for its mail provider, built from live DNS, in order, with the reason for each. Called without payment it returns a free preview of the fixes plus an x402 payment request for $0.25 USDC on Base (or 250 credits with api_key); a domain that needs no new records gets its advice free.

`monitor_sending_domains`Free for up to 3 domains per call. Report what changed in SPF, DKIM, DMARC, MX, MTA-STS, TLS-RPT and BIMI since a previous run. Pass the `snapshots` object returned by the previous call as `previous`; the server stores nothing. The first call returns a baseline with no changes.	Free for up to 3 domains per call.

`verify_email`Check an email address: syntax, whether its domain accepts mail, typo suggestion, disposable and shared-mailbox flags. Checks the domain, not the individual inbox. Costs one credit with an API key (POST /v1/agent/provision returns a key with 100 free credits), or $0.01 USDC on Base per call over x402.

`watch_sending_domains`Hosted monitoring. Register domains for a daily server-side check of SPF, DKIM, DMARC, MX, MTA-STS, TLS-RPT and BIMI; when something changes, the changes are POSTed as JSON to your https webhook_url. Free for up to 3 domains (renew every 30 days). For 4 to 20 domains in one watch, call without a pass: the result is an x402 payment request for the pass that covers them ($5 for up to 50 domains), payable in params._meta["x402/payment"] or with api_key credits; the paid call returns the pass and starts the watch. Returns a token to list or delete the watch.	Hosted monitoring.
