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 | $0.00100 | $0.02388 |
| Opus 5.5 | $0.00040 | $0.00955 |
| Sonnet 5.5 | $0.00020 | $0.00478 |
| Haiku 4.5 | $0.00010 | $0.00239 |
Grade A, and why
alchemy-api 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 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

AI + Alchemy API Integration Guide
Prerequisites
- Create a free API key at https://dashboard.alchemy.com/
- Export the key:
export ALCHEMY_API_KEY=<your-key> - If no API key is available, use the alchemy-agentic-gateway skill instead (wallet-based auth).
Mandatory Routing Gate (Hard Requirement)
Before the first network call or implementation step, you MUST ask the user the following question and wait for an explicit answer:
Do you want to use an existing Alchemy API key, or should I use the agentic gateway flow instead?
If the user chooses the API key path, continue with this skill.
If the user chooses the agentic gateway path, switch to the alchemy-agentic-gateway skill immediately and follow its existing wallet flow.
If the user chooses the API key path but ALCHEMY_API_KEY is unset or empty, tell them they can create a free API key at https://dashboard.alchemy.com/ or switch to the alchemy-agentic-gateway skill.
You MUST NOT call any keyless or public fallback (including .../v2/demo) unless the user explicitly asks for that endpoint.
Execute no network calls before this gate is evaluated.

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.

alchemy-api is a skill published in the GitHub repository moonpay/skills (111 stars, last pushed 3d ago), licensed MIT. It adds 100 tokens to every session and 2,388 once invoked, about $0.0004 per session on Opus 5.5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
