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.

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 | $0.00157 | $0.01843 |
| Opus 5 | $0.00078 | $0.00922 |
| Sonnet 5 | $0.00031 | $0.00369 |
| Haiku 4.5 | $0.00016 | $0.00184 |
Grade A, and why
public-apis 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 10d 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.

Public APIs — 免费 API 推荐助手
数据来源：public-apis/public-apis（GitHub 407K+ stars） 收录了 1425 个免费 API，覆盖 51 个分类 同步日期：2026-03-12
工作流程
- 理解需求 — 用户想实现什么功能？是前端调用（需要 CORS）还是后端？对认证复杂度有偏好吗？
- 匹配分类 — 从下方分类索引中找到 1-3 个最相关的分类。分类名本身语义清晰，大部分情况可以直接匹配；对于不太直观的映射，参考底部的「易混淆分类映射」。
- 读取 reference 文件 — 用 Read 工具加载对应的
references/<slug>.md，文件内是该分类下所有 API 的表格。 - 筛选并推荐 3-5 个 API — 优先考虑：
- 功能与需求的匹配度（最重要）
- 认证简单性：无需认证 >
apiKey>User-Agent>OAuth - HTTPS 支持（优先 Yes）
- CORS 支持（前端场景优先 Yes）
- 结构化输出 — 使用下方的推荐格式呈现结果，给出推荐理由帮助用户决策。

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.
- 10d ago First seen · 149 lines · 157 tokens per session scan A 36cfcef76b8c
public-apis is a skill published in the GitHub repository guihai24/openskills (2 stars, last pushed 5d ago), licensed MIT. It adds 157 tokens to every session and 1,843 once invoked, about $0.0008 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
