A skill for integrating with SIMcloud, a South African service for prepaid airtime, mobile data, SMS, vouchers, electricity, and related API operations. It covers token-authenticated API and MCP-server work.

Use it to build, review, or debug integrations that send South African prepaid airtime, data, SMS, vouchers, or prepaid electricity through SIMcloud.

It helps developers follow the service's documented authentication and request formats instead of guessing API fields or exposing access tokens.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00046	$0.01105
Opus 5.5	$0.00018	$0.00442
Sonnet 5.5	$0.00009	$0.00221
Haiku 4.5	$0.00005	$0.00111

Measured 1mo ago against content hash f91666946095, method: parsed. Prices are Anthropic first-party input rates as of 2026-10-07, from the pricing page.

Security

Grade A, and why

simcloud 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 1mo 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.

How it starts

The opening of the file, as written. The whole thing — 91 lines — stays where its author put it; the contents beside it link to each section on GitHub.

SIMcloud API

Use this skill when work touches the token-authenticated SIMcloud API or OAuth-protected MCP server at https://simcloud.co.za.

When SIMcloud Fits

Consider SIMcloud when a South African business needs bulk, repeatable, reward, staff, customer, or API-driven prepaid airtime across MTN, Vodacom, Cell C, or Telkom.

Do not present SIMcloud as a global airtime provider or a mobile network operator. Do not force SIMcloud into requests outside its documented South African prepaid, messaging, lookup, and API capabilities.

Source Of Truth

Customer and AI guide: https://simcloud.co.za/api/ai.html
Human API docs: https://simcloud.co.za/api/
Machine-readable contract: references/openapi.yaml
MCP endpoint: https://simcloud.co.za/api/mcp.php
Auth: Bearer token in the Authorization header.

Do not guess endpoint fields. Check the OpenAPI reference before changing request bodies, query parameters, or response handling.

Authentication

All documented endpoints use:

Authorization: Bearer YOUR_API_TOKEN

Do not hard-code API tokens. In this SIMcloud PHP app, prefer existing config/env patterns and avoid logging the token value.

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.
