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.

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 | $0.00101 | $0.02861 |
| Opus 5.5 | $0.00040 | $0.01144 |
| Sonnet 5.5 | $0.00020 | $0.00572 |
| Haiku 4.5 | $0.00010 | $0.00286 |
Grade A, and why
alpaca-broker-funding-transfers 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 7d 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 — 133 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Alpaca Broker API — Funding & Transfers
Getting cash into and out of end-user accounts. There are three external rails plus Instant Funding, and for the external rails the model splits cleanly into bank links (persistent) and transfers (the actual money movement).
Read
alpaca-broker-integrationfirst for base URLs and auth (client-credentials Bearer token; legacy Basic still works). For moving cash between accounts in your omnibus (vs. to/from the outside world), seealpaca-broker-journals— that's a different mechanism.

1. The funding model
External bank ──(relationship: a persistent link)──┐
├──> Transfer (the money movement) ──> Account cash
ACH relationship (rail A: ACH, US domestic) │
Bank relationship (rail B: wire, domestic + intl) │
Funding wallet (rail C: v1beta, multi-currency) ┘
- A relationship links an external bank. It moves no money and has its own status; for wires it must be
APPROVEDbefore a transfer can progress. - A transfer references a relationship by ID and moves the money. One relationship backs many transfers.
| Rail | transfer_type |
Directions | Relationship | Notes |
|---|---|---|---|---|
| ACH | ach |
INCOMING + OUTGOING |
ACH relationship (relationship_id) |
US domestic; set up via Plaid processor_token (recommended) |
| Wire | wire |
OUTGOING only |
Bank relationship (bank_id) |
Domestic + international (SWIFT). Incoming wires are pushed by the sending bank and booked automatically |
| Funding wallet | (separate /v1beta API) |
incoming / outgoing (lowercase) |
Funding-wallet recipient bank | Multi-currency, swift_wire/local_rails |
| Instant Funding | (separate /v1/instant_funding API) |
credit only | none — you collect the payment yourself | Extends buying power immediately, settled in bulk by wire on T+1. See §8 |
What ships with it

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.
