Token cost

What it costs to keep this loaded

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.

Security

Grade B, and why

telnyx-email-suppressions-curl scanned grade B with 2 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 13d 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.

Telnyx Email Suppressions - curl

Installation

# curl is pre-installed on macOS, Linux, and Windows 10+
# jq is required for the import polling examples below:
#   macOS: brew install jq
#   Debian/Ubuntu: sudo apt-get install jq

Setup

export TELNYX_API_KEY="YOUR_API_KEY_HERE"

All examples below use $TELNYX_API_KEY for authentication and the API base URL https://api.telnyx.com/v2.

Error Handling

All API calls can fail with network errors, authentication errors (401), or framework errors (406). List-query validation failures return 400, resource lookups can return 404, and JSON body validation failures normally return 422. Inspect the HTTP status and the top-level .errors array before continuing:

response_file=$(mktemp)
status=$(curl --silent --show-error \
  --output "$response_file" \
  --write-out '%{http_code}' \
  -H "Authorization: Bearer $TELNYX_API_KEY" \
  "https://api.telnyx.com/v2/email_blocks")

if [ "$status" -lt 200 ] || [ "$status" -ge 300 ]; then
  printf 'Telnyx API error (HTTP %s):\n' "$status" >&2
  jq . "$response_file" >&2
  rm -f "$response_file"
  exit 1
fi
jq . "$response_file"
rm -f "$response_file"

Common statuses are 400 malformed query or import, 401 invalid API key, 404 resource not found, 409 group still has active suppressions, 413 import too large, and 422 invalid request attributes. A successful delete may return 204 No Content; do not attempt to parse that response as JSON.

Important Notes

  • Account isolation: Every lookup is scoped to the authenticated account. A malformed UUID or a UUID owned by another account is reported as 404.
  • Normalized addresses: Recipient addresses are trimmed and lower-cased. The from address on a manual block is also normalized.
  • Pagination: Most list operations use page[number] and page[size] (maximum 100). The main block list also supports opaque cursors. Do not combine offset and cursor modes.
  • URL encoding: Percent-encode an email address placed in a URL path. For example, use alice%40example.com, not an untrusted raw string.
  • Idempotency: Creating a block or adding a group suppression returns 200 when the matching suppression already exists and 201 when a row is created.
