Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00037 | $0.00601 |
| Opus 5 | $0.00018 | $0.00300 |
| Sonnet 5 | $0.00007 | $0.00120 |
| Haiku 4.5 | $0.00004 | $0.00060 |
Grade A, and why
email-validate-post-email scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Endpoint
POST https://requiems.xyz/v1/validation/email
Validate Email
Validates a single email address and returns a full breakdown of syntax validity, MX record status, disposable domain check, normalized form, and any typo suggestion.
Parameters
| Name | Type | Required | Location | Description |
|---|---|---|---|---|
email |
string | yes | body | The email address to validate. |
Request Example
{
"email": "[email protected]"
}
Response Example
{
"data": {
"email": "[email protected]",
"valid": false,
"syntax_valid": true,
"mx_valid": false,
"disposable": false,
"normalized": "[email protected]",
"domain": "gmial.com",
"suggestion": "gmail.com"
},
"metadata": {
"timestamp": "2026-01-01T00:00:00Z"
}
}
Response Fields
| Field | Type | Description |
|---|---|---|
email |
string | The email address exactly as supplied in the request body; null when syntax is invalid |
valid |
boolean | Overall validity. True only when the address passes syntax validation and the domain has at least one MX record |
syntax_valid |
boolean | Whether the address is syntactically valid according to RFC 5322 |
mx_valid |
boolean | Whether the domain has at least one MX record, meaning it can receive email |
disposable |
boolean | Whether the address uses a known disposable or temporary email domain |
normalized |
string | The canonical form of the address after normalization (lowercase, plus-tag removal, alias-domain resolution). Null when syntax is invalid |
domain |
string | The domain part of the address (after @). Null when syntax is invalid |
suggestion |
string | A corrected domain name when the supplied domain looks like a typo of a well-known provider (e.g. gmial.com → gmail.com). Null when no close match is found or the domain is already correct |
Errors
422validation_failed — The email field is missing from the request body.400bad_request — The request body is missing, not valid JSON, or contains unknown fields.500internal_error — Unexpected server error.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

email-validate-post-email is a skill published in the GitHub repository bobadilla-tech/requiems-api-skills (2 stars, last pushed 5d ago), licensed MIT. It adds 37 tokens to every session and 601 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings.
