https://2s.io/api/domain/email-security

Shares a payout wallet with 441 other endpoints — its adoption is attributed from that shared wallet's traffic, not earned exclusively.

Grade a domain's email-authentication and DNS-security posture from live DNS in one call: SPF, DMARC (policy + alignment), DKIM (for the supplied or common selectors), MTA-STS, TLS-RPT, DNSSEC, CAA, and BIMI. Pass domain (and optional dkimSelector). Returns an overall letter grade, a summary (spf/dmarcPolicy/dkim/mtaSts/dnssec/caa/bimi + spoofingProtected), and a per-mechanism block with the raw record, parsed tags, and specific issues (e.g. 'DMARC p=none — monitor only', 'SPF ~all soft-fail', 'no MTA-STS'). Sourced from live public DNS via DNS-over-HTTPS — an LLM cannot know a domain's current records. For deliverability/anti-spoofing audits, vendor security review, and phishing-resistance checks. DKIM is selector-based (selectors aren't enumerable), so 'not found' only means none of the checked selectors resolved.

Composite reliability — the weighted average of the dimensions below, on a 0–100 scale.
Availability
100

How often it was reachable when we probed it (weight 35%).

Latency
100

How quickly it answers when it is up — fast scores high (weight 20%).

Security
100

Whether it serves over working TLS / https (weight 15%).

Transparency
61

Whether the operator disclosed what it does — description, schema, identity (weight 15%).

Activity
5

Observed on-chain payments to this endpoint's wallet — transactions, volume, and distinct paying wallets over the last month (weight 15%; not yet measured when we have not seen its wallet settle).

Confidence 100% — how much probe evidence backs this score. A thin history is flagged, not hidden.

This payout wallet is shared: figures cover all 442 endpoints paid at it, since payments cannot be attributed to one of them. Only payments settled on chains and facilitators we index.

Linked by wallet — likely same operator

On-chain agent identity and the x402 endpoint that shares its settlement wallet.
