Measured tools (8)

• list_models read-only

  Models on the broker with benchmark scores per category (0–1, measured by us), price per 1M tokens (default USD, any currency from GET /api/v1/broker/currencies) and regions. Filter by category, region and price; sorted by score in the category, else by price.

  Parameters:

  • limit — integer
  • region — string
  • category — string
  • currency — string — ISO 4217 code, default USD
  • max_price_per_mtok — number — Max output price per 1M tokens, in currency

  Hints: read-only yes · destructive not declared · idempotent not declared · open-world no

• get_model read-only

  One model from list_models by id: measured scores per category, price per 1M tokens (default USD), regions, context and capabilities.

  Parameters:

  • id (required) — string
  • currency — string — ISO 4217, default USD

  Hints: read-only yes · destructive not declared · idempotent not declared · open-world no

• recommend_model read-only

  Picks from the published catalog (our own benchmark scores, list prices): best = highest score in the category, best_value = score per output price, plus alternatives. Only measured models are recommended. Returns chat_arguments for that model and a routing object to let the broker pick per request.

  Parameters:

  • category (required) — string
  • region — string
  • currency — string — ISO 4217, default USD
  • min_score — number
  • capabilities — array
  • max_price_per_mtok — number — Max output price per 1M tokens, in currency

  Hints: read-only yes · destructive not declared · idempotent not declared · open-world no

• estimate_cost read-only

  Cost estimate at list price for a model and token counts, in your currency. The bill follows the offer the router actually picks (broker.cost in the chat result).

  Parameters:

  • model (required) — string
  • currency — string — ISO 4217, default USD
  • input_tokens — integer
  • output_tokens — integer

  Hints: read-only yes · destructive not declared · idempotent not declared · open-world no

• chat

  Sends messages to the broker (OpenAI chat completions). model defaults to `taylor` (strongest measured model); any id from list_models works. routing sets criteria per request, e.g. {"category": "coding", "level": "best"}. Needs Authorization: Bearer ast_sk_… — billed like the REST API.

  Parameters:

  • model — string
  • prompt — string — Shortcut for a single user message
  • routing — object
  • messages — array
  • max_tokens — integer

  Hints: read-only no · destructive not declared · idempotent not declared · open-world yes

• get_balance read-only

  Balance, credit limit and spend this month (CHF, the book currency), billing mode and payment currency of the account behind Authorization: Bearer ast_sk_….

  Hints: read-only yes · destructive not declared · idempotent not declared · open-world no

• report_outcome

  Tell the broker if the answer to a request worked for your task — request_id comes from broker.receipt of every chat answer. Outcomes appear per model in list_models as reported (failures_30d / outcomes_30d), so the scores are checked against real tasks. No refund, no price change.

  Parameters:

  • request_id (required) — string
  • outcome (required) — string
  • reason — string

  Hints: read-only no · destructive no · idempotent yes · open-world no

• create_account

  Creates a card checkout (Stripe) for a new broker account — same as POST /api/v1/broker/accounts. Give checkout_url to your human; after payment the API key is shown exactly once at status_url (GET, poll until 200). topup: amount 10/25/50, monthly: limit 50/100/250 (USD/EUR/CHF; other currencies: GET /api/v1/broker/currencies). Omit category and level to choose per request.

  Parameters:

  • billing (required) — string
  • level — string
  • limit — integer — monthly credit limit in currency
  • amount — integer — topup amount in currency
  • category — string — optional, with level: a fixed performance promise
  • currency — string

  Hints: read-only no · destructive no · idempotent not declared · open-world yes
