Documentation

The full Resend API (100 endpoints across emails, broadcasts, audiences, contacts, domains, templates, webhooks) plus a local SQLite cache that powers cross-resource queries the dashboard and SDK cannot answer.

The official Resend CLI is fast and one-shot per command; this CLI is the agent-native companion with --json --select --dry-run consistency, FTS5 search over sent emails, and rollups (audiences inventory, broadcasts performance, deliverability summary, contacts where, emails to ) that exist only because every Resend resource is mirrored locally.

Created by @giacaglia (Giuliano Giacaglia).

Quick Start

# Verify RESEND_API_KEY and reach api.resend.com.
resend-pp-cli doctor

# Populate the local SQLite store with audiences, contacts, domains, broadcasts, and templates.
resend-pp-cli sync --full

# First read — confirm sync landed.
resend-pp-cli domains list --json --select id,name,status

# Cross-audience rollup the official CLI cannot produce.
resend-pp-cli audiences inventory --json

# FTS across emails, contacts, broadcasts, and templates.
resend-pp-cli search invoice --json

Unique Features

These capabilities aren't available in any other tool for this API.

Cross-resource queries over local state

emails to — Every email sent to a single recipient address, with delivery status and timestamps, ordered newest-first.

Reach for this when an agent needs to reconstruct what a single user has received — support tickets, GDPR exports, dispute investigations.
```
resend-pp-cli emails to <your-email> --json --select id,subject,status,sent_at
```
emails timeline — Collapsed event chain for a single email: sent → delivered → opened → clicked → bounced, in one ordered table.

Use when debugging 'why didn't this arrive?' — one command shows whether it was sent, delivered, opened, or bounced and when.
```
resend-pp-cli emails timeline 4ef9a417-d4ff-4ec5-9af2-c80a4d5d2c1f --json
```
audiences inventory — Per-audience rollup: contact count, unsubscribed count, last-broadcast timestamp, recent open-rate.

Use before planning a campaign — quickly see which audiences are healthy and recently engaged.
```
resend-pp-cli audiences inventory --json
```
contacts where — Find every audience, segment, and topic a contact (by email or name) belongs to in one query.

Use when triaging unsubscribe requests, GDPR deletions, or 'why is bob getting this email?'.
```
resend-pp-cli contacts where <contact-email> --json --select audience_name,subscribed
```

Aggregate analytics from local store

broadcasts performance — Open / click / bounce rate across all broadcasts, sortable; not limited to a single broadcast or 30-day window.

Use to compare campaign performance across the lifetime of the account.
```
resend-pp-cli broadcasts performance --json --select broadcasts,count,status
```
domains health — Verification + DKIM/SPF/DMARC status across every domain in one table, flags missing or unverified records.

Use on call-out / deliverability incidents to confirm all sending domains are fully verified.
```
resend-pp-cli domains health --json
```
deliverability summary — Bounce rate, complaint rate, and suppression count over a rolling window (default 7d) computed from local event data.

Use weekly to monitor IP/domain reputation trends before they cause deliverability incidents.
```
resend-pp-cli deliverability summary --window 7d --json
```

Operational hygiene

api-keys rotation — API keys sorted by age + last-used timestamp (joined from logs); flags stale keys older than N days.

Use during quarterly security reviews — find unused keys that should be rotated or revoked.
```
resend-pp-cli api-keys rotation --older-than 90d --json
```

# JSON for scripting and agents

# Filter to specific fields
resend-pp-cli api-keys list --json --select id,name,status

Agent Usage

This CLI is designed for AI agent consumption:

Non-interactive - never prompts, every input is a flag
Pipeable - --json output to stdout, errors to stderr
Filterable - --select id,name returns only fields you need
Previewable - --dry-run shows the request without sending
Explicit retries - add --idempotent to create retries and --ignore-missing to delete retries when a no-op success is acceptable
Confirmable - --yes for explicit confirmation of destructive actions
Piped input - write commands can accept structured input when their help lists --stdin
Offline-friendly - sync/search commands can use the local SQLite store when available
Agent-safe by default - no colors or formatting unless --human-friendly is set

Exit codes: 0 success, 2 usage error, 3 not found, 4 auth error, 5 API error, 7 rate limited, 10 config error.

Health Check

resend-pp-cli doctor

Verifies configuration, credentials, and connectivity to the API.

Configuration

Config file: ~/.config/resend-pp-cli/config.toml

Static request headers can be configured under headers; per-command header overrides take precedence.

Environment variables:

Name	Kind	Required	Description
`RESEND_API_KEY`	per_call	Yes	Set to your API credential.

Troubleshooting

Authentication errors (exit code 4)

Run resend-pp-cli doctor to check credentials
Verify the environment variable is set: echo $RESEND_API_KEY Not found errors (exit code 3)
Check the resource ID is correct
Run the list command to see available items

API-specific

401 unauthorized on every command — Confirm RESEND_API_KEY is exported. Keys start with re_… and are visible at resend.com/api-keys.
Local commands return zero rows — Run resend-pp-cli sync --full — local-only commands read from the SQLite cache.
429 rate limit — Resend documents Retry-After. Lower --rate-limit (default 0 = unbounded) or run sync in off-hours.
Domain reports unverified after creation — Resend caches DNS for ~24h; domains verify <id> triggers re-check, and domains get <id> shows current DKIM/SPF/DMARC state.
