## When to prefer this

Choose this endpoint when you need a ready-to-use cold email draft grounded in proven outreach patterns, especially in a sales or B2B context, and you want to skip blank-page copywriting. It complements the sibling 'grade' endpoint (which scores cold emails) and 'deliverability' endpoint (which audits sending domains), making it ideal for a full cold-email automation pipeline.

## Known failure modes

- Missing or malformed query parameters may return a 400 error or empty template
- Payment not completed (x402 flow not fulfilled) results in a 402 Payment Required response
- Rate limiting or worker timeout may return a 5xx error
- No matching template for the given context may return a generic or empty draft

## How this service works

Paid micro-utilities for cold-email outreach agents: domain deliverability audits, cold-email grading, template generation, plus a tools toolbox (hashing, JWT decode, IDs, slugs, JSON, regex, crypto prices, domain age, weather). Paid via x402 (USDC on Base). One signature per call. No keys. FREE CHECK: GET /preview/<paid-path> (same URL with /preview/ prefix) returns a 200 demo sample - verify output shape before paying. PAID CALL: GET the url -> 402 challenge -> sign + retry with X-PAYMENT -> settled on-chain (USDC, Base). Ready-to-paste client: GET /llms.txt section "Pay in one call". Catalog+MCP twin: /llms.txt.

## Output

A personalized cold email body drafted from proven outreach templates, ready to send or lightly customize, tailored to the specified outreach context and recipient type.
