Give a Solana address; get the exact message to sign. A signature, not a transaction: no fee, nothing moves. Then call agent_session_verify with the base64 signature.
DiscoveredThe address, the exact message from agent_session_start and its base64 Ed25519 signature. Returns a session token to pass as `session` to every later call (valid 30 days, revocable from the account page).
DiscoveredWhether an entry has a verified claim, by which proof and when — never by whom.
DiscoveredNames the entry (scheme + value, e.g. lei); returns the proof domain the register lists and the token to place as a TXT record, a well-known file, or via a verified email there.
DiscoveredEvery claim of this account with its status and, while pending, the instructions.
DiscoveredThe server reads DNS, the well-known file and the verified email; verified claims are badges on the profile.
DiscoveredThe columns, which of them are numeric, the row count and the provenance banner of the Issafu dataset. Call this first to learn the schema.
DiscoveredThe rows of the Issafu dataset whose column is any of the given values, in the order given — for "X vs Y" questions.
DiscoveredThe source, the date it was computed, the licence and the citation for the Issafu dataset. Read this to attribute a figure correctly.
DiscoveredThe rows of the Issafu dataset where a column equals a value exactly (case-insensitive).
DiscoveredRows of the Issafu dataset whose cells contain the query (case-insensitive), up to 50.
Discoveredcount, min, max, mean, median and sum of a numeric column of the Issafu dataset (grouping commas and currency are handled; non-numeric rows are excluded and counted).
DiscoveredThe highest (or lowest) rows of the Issafu dataset by a numeric column — "which is the most/least X".
DiscoveredRead first. States plainly what submit_enquiry does on Issafu: it starts an enquiry with human providers who quote directly. Nothing is bought, ordered or paid; no quote is guaranteed; it is free. Also returns who receives the details, the consent wording, and how the person confirms.
DiscoveredEvery field of the Issafu enquiry: key, label, type, whether required, help text and the allowed options where there are any. Pass answers to submit_enquiry keyed by field key.
DiscoveredEvery entity of Issafu register, 200 a page, with provenance. Needs an access key (Authorization: Bearer); export pages are metered per key per day. Without a key the answer says how to get one.
DiscoveredThe Issafu register entities in one region (a state or a jurisdiction, by id or name), optionally for one service, 50 a page.
DiscoveredWhich fields the Issafu register register carries and on how many entities, the regions and services, the identifier schemes, and how to cite it. Call this first.
DiscoveredEntities of Issafu register whose name, commercial name, website, address or authority contains the query, optionally within a region (id or name) and a service (slug or name). Up to 50 rows.
DiscoveredThe Issafu register entry for a firm, by its register identifier (scheme + value, e.g. lei) or by the slug of its page. Exact match; returns the whole record with its page.
DiscoveredThe SERVER finds the transfer by reference and reads the treasury's balance change; a short or wrong-token transfer is reported by name and not credited. On success the listing enters review.
DiscoveredWhat a listing on Issafu is, what it costs, how it is paid, who publishes it, and every profile field it takes. Read this to the person first.
DiscoveredCreates a listing draft on Issafu. Send the fullest profile you can (listing_describe lists the fields); a scam-shaped or off-list field is refused by name. Returns the listing id and status awaiting_payment.
DiscoveredReturns a Stripe Checkout URL at the site's price. A human completes it in a browser; the site learns of payment from Stripe's verified event, never from the browser.
DiscoveredSend a Stripe payment method id (pm_...) the agent is entitled to use; the server charges the SITE's price off-session. Answers succeeded (the listing enters review) or requires_action (use listing_pay_card for a human); never charges an amount you name.
DiscoveredReturns the Solana Pay transfer request: recipient, exact amount, USDC mint and a unique reference. Pay it from the wallet (include the reference as a read-only key), then call listing_confirm_usdc.
DiscoveredEvery listing of this account with its status (awaiting_payment, pending_review, published, refused, withdrawn, expired).
DiscoveredThe clauses a listing is judged by, their version (send it back as termsVersion), and every profile field the directory takes.
DiscoveredTakes down a listing of this account.
DiscoveredWhat firms have added on top of the register (published rows only), optionally for one register entry.
DiscoveredThe Sponsored slot's contents for a page (home | region | leaf); labelled as sponsored in the answer.
DiscoveredSubmits an enquiry to Issafu — NOT a purchase, NOT a guaranteed quote. Step 1: call with the answers (keyed by field key from enquiry_fields) and consent=true; it validates and returns a summary, the consent line and a confirmation token — show the person the summary and the consent line. Step 2: only if the person agrees, call again with the same answers, consent=true and the confirmation token; the enquiry is then submitted, and the person receives an email with a link they must click before any provider sees it. Consent means the person has read and agreed to: "By sending this you agree the Issafu team reads your enquiry and replies by email. We do not pass it to anyone else."
