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 | $0.00141 | $0.02762 |
| Opus 5 | $0.00071 | $0.01381 |
| Sonnet 5 | $0.00028 | $0.00552 |
| Haiku 4.5 | $0.00014 | $0.00276 |
Grade A, and why
agentic-gateway 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 5d 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 Agentic Gateway (x402 / MPP)
Notice: This repository is experimental and subject to change without notice. By using the features and skills in this repository, you agree to Alchemy's Terms of Service and Privacy Policy.
A specialized app-integration skill for using Alchemy's developer platform from application code without a standard API key. Authentication is wallet-based (SIWE for EVM, SIWS for Solana). Each request is paid per-call with USDC (x402) or USDC/credit-card (MPP).
When to use this skill
Use agentic-gateway 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
- AND at least one of:
- No Alchemy API key is available
- The user is an autonomous agent that needs to pay for itself (per-request, no upfront key)
- The user explicitly wants x402 or MPP
- No other runtime path exists and they intentionally choose the gateway
This is a specialized app-integration path. The default app path is alchemy-api with an API key.
When to use a different skill
| Situation | Use this skill instead |
|---|---|
Live agent work in this session (queries, admin, on-machine automation) and @alchemy/cli is installed locally — or both CLI and MCP are available |
alchemy-cli |
| Live agent work in this session and only MCP is wired into the client (no CLI) | alchemy-mcp |
| Live agent work and neither is available | install alchemy-cli and use alchemy-cli |
| Application code with an Alchemy API key (the normal path) | alchemy-api |
Do not use this skill to run ad-hoc live queries from inside the agent session — that's the alchemy-cli / alchemy-mcp path. This skill is for code that ships and pays per-request.
Mandatory preflight gate

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.

agentic-gateway is a skill published in the GitHub repository alchemyplatform/alchemy-claude-plugin (6 stars, last pushed 2mo ago), licensed MIT. It adds 141 tokens to every session and 2,762 once invoked, about $0.0007 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). It is 100% identical to agentic-gateway, differing in 0 lines, and is treated as a copy.
