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.

SkillSpector: 7 findings, up to high
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00040 | $0.04926 |
| Opus 5.5 | $0.00016 | $0.01970 |
| Sonnet 5.5 | $0.00008 | $0.00985 |
| Haiku 4.5 | $0.00004 | $0.00493 |
Grade A, and why
telnyx-x402-payment scanned grade A with 1 finding 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 2mo 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 x402 Cryptocurrency Payment
Fund a Telnyx account with USDC on the Base blockchain using the x402 payment protocol. The flow has three steps: get a quote, sign the payment client-side, and submit for settlement.
Feature Flag: x402 payments are gated behind the
X402_PAYMENTS_ENABLEDfeature flag. If not enabled for the account, the API returns403 Forbidden.
Prerequisites
- Telnyx API key (
TELNYX_API_KEY) - Crypto wallet with USDC on Base network (chain ID:
eip155:8453) - USDC contract on Base:
0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913
Environment Variables
| Variable | Required | Description |
|---|---|---|
TELNYX_API_KEY |
Yes | Telnyx API v2 key |
Step 1: Get a Quote
Request a quote for the USD amount to fund. Per-payment minimum and maximum limits apply; they are configurable and may change, and the API's 422 error messages state the current values. Quotes expire after 5 minutes.
curl -s -X POST "https://api.telnyx.com/v2/x402/credit_account/quote" \
-H "Authorization: Bearer $TELNYX_API_KEY" \
-H "Content-Type: application/json" \

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.

telnyx-x402-payment is a skill published in the GitHub repository team-telnyx/ai (224 stars, last pushed today), licensed MIT.
