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 | $0.00160 | $0.03681 |
| Opus 5.5 | $0.00064 | $0.01472 |
| Sonnet 5.5 | $0.00032 | $0.00736 |
| Haiku 4.5 | $0.00016 | $0.00368 |
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 14d 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.

Alchemy API (with API Key)
Reference and integration guide for wiring Alchemy APIs into application code using a standard API key. This file alone is enough to ship a basic integration; the references/ directory contains deeper coverage of every product surface.
When to use this skill
Use alchemy-api when all of the following are true:
- The user is wiring Alchemy into application code (server, backend, dApp, worker, script) that runs outside the current agent session
- They have, or are willing to create, an Alchemy API key (free at dashboard.alchemy.com)
This is the preferred app-integration path for normal server/backend usage.
When to use a different skill
| Situation | Use this skill instead |
|---|---|
| Live agent work in this session (queries, admin, on-machine automation); no API key needed, sign in with OAuth | alchemy-mcp |
Do not use this skill to run ad-hoc live queries from inside the agent session — that's the alchemy-mcp path. This skill is for code that ships.
Mandatory preflight gate
Before writing application code or making any network call:
- Confirm the user is building application code (not asking the agent to run a live query). If the user is asking for live work, redirect to
alchemy-mcp. - Check
$ALCHEMY_API_KEYis set without printing it (e.g.[ -n "$ALCHEMY_API_KEY" ] && echo set || echo missing). - If
$ALCHEMY_API_KEYis unset or empty, take the first of these that applies:- For live work in this session, use the
alchemy-mcpskill (the bundled Alchemy MCP server signs in with OAuth, no API key needed), or - For application code, tell the user they can create a free API key at https://dashboard.alchemy.com/ and copy it into
ALCHEMY_API_KEY.
- For live work in this session, use the
You MUST NOT call any keyless or public fallback (including .../v2/demo) unless the user explicitly asks for that endpoint. No public RPC endpoints (publicnode, llamarpc, cloudflare-eth, etc.) as a fallback.

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 alchemyplatform/alchemy-claude-plugin (7 stars, last pushed 15d ago), licensed MIT. It adds 160 tokens to every session and 3,681 once invoked, about $0.0006 per session on Opus 5.5. A static security scan graded it A with 1 finding (makes network calls). It is 98% identical to alchemy-api, differing in 95 lines, and is treated as a copy.
