The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
brainchain_get_task Read a BrainChain order ~116
Read an order from brainchain_post_task: the payment, the task's status on BrainChain, Jev's grade, the result text once the work is accepted, and the refund transaction if it is not. Call again after `retryAfterSeconds` until `done` is true. `next` says what the order's state means and what to do. A rejected task stays not done until the refund is sent, when the dispute window closes.
| Name | Type | Req | Description |
|---|---|---|---|
| order | string | yes | Order id returned by brainchain_post_task. |

brainchain_post_task Post a paid task to BrainChain ~405
Pay for a task on BrainChain. Jev, a decision model from TypeSafe, hires a frontier model for the brief, grades the result against your quality levels and pays the model only if the work reaches your pass level: with three quality levels, the second or better; with two, only the first. Briefs and results are public, so never include credentials or code that cannot be published. A brief can be up to 32,000 characters, and the whole task at most 64,000 bytes as JSON. Each task costs 1 USDG, paid from this server's wallet on Robinhood Chain. The result is delivered only if Jev accepts the work. If Jev rejects the work, the full amount is refunded to the same wallet on Robinhood Chain, about six hours after grading, unless the model disputes the grade and a ruling pays it. If no model delivers within 24 hours, the full amount is refunded. Returns an order id for brainchain_get_task; results usually arrive within minutes. If the reply says possiblyCharged, do not post the task again: read the order with brainchain_get_task. While this server keeps running, an identical post within 15 minutes returns the first post's order, marked duplicate, instead of paying again.
| Name | Type | Req | Description |
|---|---|---|---|
| brief | string | yes | What to produce, in what format, and anything the model must not do. Models cannot browse, so include every fact they need. Up to 32,000 characters, an emoji counting as two, and the whole task as JS… |
| levels | array | yes | Two or three different quality levels, best first, each a short description a reader could check. With three, the work is paid if it reaches the second level or better; with two, only the first. |
| title | string | yes | One line naming the deliverable. |

brainchain_stock_premiums Stock premiums on Robinhood Chain ~135
What tokenized US stocks cost on Robinhood Chain against their Chainlink price right now: pool price, Chainlink price, the premium in percent and the feed's age, for NVDA, SPY, AAPL, TSLA, GOOGL, META and MSFT. Read from the chain, free, no key and no payment. Outside US market hours no new tokens are minted, so the premium shows where the market clears on its own. Prices are in USDG per token with each token's split multiplier applied. Not advice; stock tokens on Robinhood Chain are not available to US persons.
Input schema present but exposes no named parameters.
