Tools
| Tool | Description | Behaviour |
|---|---|---|
| card_checkout | Use when a person, not the agent, will pay a quote by card: returns a Stripe Checkout link (url) for the quote's maximum, at least $0.50. The work runs when the payment completes; the charge follows the work delivered, never above the quote, the rest refunded, and an order that delivers nothing is refunded in full (a card order quoted under $0.50 keeps the $0.50 minimum). An agent paying itself uses x402 at POST /v1/openings/{quote_id} instead. | Not declared |
| find_entry | Use first when a person, work, concept, institution or operator needs a sourced knowledge object: looks the name up in the Negative of the Negative (/non), free. Returns the entry (its page, data and status) when one exists; the candidates and what tells them apart when the name is ambiguous; or, when none exists, the request for a free construction quote to pass to get_quote. Does not check a sentence (use open_sentence) and charges nothing. | Not declared |
| get_quote | Use to price work before paying: a whole Wikipedia article (article: its link or title, or oldid), read sentence by sentence at a tier, or a commission on an object (object with kind entity or operator, name, and for an operator its strings; commission construct or open): construct gives an entity the encyclopedia holds an alternative to its article, and one it lacks its first account. Or random open (a random article's cited sentence, read at tier check or opening) or random construct (a random Wikipedia article as an alternative, or an object the archive names with no /non entry); the quote says what was picked. Free; returns a quote_id with each deliverable, its line and the maximum, or, for a commission, a quote_id whose price appears at order_status within minutes. Pay a quote over x402 at POST /v1/openings/{quote_id}, or have a person pay with card_checkout. For one sentence use open_sentence; to see whether an object already exists use find_entry first. | Not declared |
| get_result | Use once order_status names a result_id: returns the delivered work. part composition (default): the usable result, each sentence's reading or the knowledge object; evidence: the full record behind it (quoted spans, source hashes, both readings, breaches, model cost); publication: whether the /non row is composed, checked, landed and public. Free to read. | Not declared |
| open_sentence | Use when one sentence from an English Wikipedia page must be checked against the sources it cites before it is quoted or relied on. Send the sentence exactly as it stands and the page's URL. Free when the sentence has already been read at the same state; otherwise returns its price (typically 22¢ opened) and the paid HTTP route (x402) that reads it. A text that is not the page's sentence exactly is answered with the page's closest sentences, nothing charged. For a whole article use get_quote with the article instead. | Not declared |
| order_status | Use after get_quote or a payment, with the quote_id: returns the state (estimating, quoted, paid and running, delivered, refunded), the quote with its lines and expiry, the order's progress, its receipt and refund, and, once delivered, the result_id to pass to get_result. Charges nothing and starts nothing. | Not declared |
