Tools 49

apply_discount_code

Apply a discount code the user gives you to a registration that isn't paid yet.

Discovered
calculate_cac_fees

CAC's official registration fees, line by line, for a business name, a limited company (by authorised share capital, default ₦1,000,000) or an NGO (Incorporated Trustees). Use it for any question about what CAC charges to register. These are government fees, not FastCAC's price.

Discovered
check_annual_returns

For a CAC business name: which annual returns are due from its registration date, which are overdue, CAC's estimated charge, and when the next one is due. Needs the registration date (it's on the certificate). Without it, the annual returns checker on fastcac.com looks the date up by BN number.

Discovered
check_business_name_compliance

CAC's verdict on a proposed name, the same check fastcac.com's name checker runs: CAC's naming rules first, then CAC's own compliance and similarity engine. Returns `tone` (ok, caveat = a certificate is needed, blocked), a plain `message`, `code` (CAC's 00-14; none when one of CAC's naming rules blocked it), `similar_names`/`most_similar_name`/`similarity_score`, and `alternatives`: names to offer, each already passing the rules (for a name missing its ending, the name with each accepted ending: Ventures, Enterprises, Services, Concepts, Hub, Fashion, Beauty, Biz, or Limited/Ltd for a company). `line_of_business` must be one of CAC's entries; anything else returns error line_of_business_invalid with `choices` to ask about, never a guess. A name ending in Limited/Ltd/PLC is checked as a company unless `name_type` says otherwise. An `error` is never a verdict: say CAC didn't answer.

Discovered
check_name_availability

Search CAC's public register for names matching or similar to a name, across every registration type (business names, companies, LLPs, trustees), ranked like fastcac.com's public search. CAC rejects a new name that's too close to any of them, active or inactive. `exact_match` is the registered name that is this name (case, spacing and the legal form like Ltd ignored), or null. close_matches come best first, each with `match` (exact, close, similar, or null when it only shares a distinctive word); a close match is often the same name with another ending (ADAEZE ENTERPRISES for "Adaeze Ventures"), which CAC treats as a clash. Lead with exact_match when there is one; when it's null, say nothing is registered under this exact name and lead with the closest matches as the clash they are. Any close match means the name is at risk; CAC makes the final call (check_business_name_compliance asks it). For an RC/BN number use search_cac_register instead.

Discovered
create_business

Start a new registration: creates the business (as a draft) with the name the user wants to register, in the workspace they're in (pass `workspace` only when they ask for the other one). A personal registration needs a verified WhatsApp number: without one it returns whatsapp_unverified (request_whatsapp_verification sets it up).

Discovered
create_share_link

Make a share link and show it as a Copy button. If one is already live, this replaces it (the old one stops working), so it shows a Confirm button first. review_enabled (status links) lets the viewer review the registration details.

Discovered
delete_business

Delete one of their businesses that hasn't been paid for (draft or pending_payment) with its registration details and documents. If it can be deleted, a Confirm button is shown and nothing is deleted until they tap it; if not, you get the reason (e.g. it's been paid for). Call it only when they ask to delete it - not when they just ask whether they can.

Discovered
fetch_nin_slip

Get their NIN slip for them from NIMC's record for their confirmed NIN, instead of them uploading a photo of it. Free to them. Only after they agree, and only once their NIN is confirmed. The slip is never shown to them.

Discovered
generate_business_names

Brainstorm CAC-registrable business names for an idea. Each name comes back already checked against CAC's registry, with `availability`: likely_available, similar_names_exist, or unchecked (CAC's search was busy).

Discovered
get_action_status

Whether the person finished a step you handed them on FastCAC (a tool returned status 'action_required' with an action_id): confirming a change, paying, uploading documents, entering their NIN or verifying WhatsApp. Returns status (pending, started, completed, failed, cancelled, expired) and next_step in words.

Discovered
get_cac_documents

For an approved registration: show Download buttons for the CAC certificate and status report, once we have them.

Discovered
get_cac_tax_id

Get the Tax ID (TIN) CAC's public search shows for a registered business. Takes company_id, rc_number and classification_id from a search_cac_register result. Returns { name, rc_number, tax_id }, or an error 'not_found' when CAC has none.

Discovered
get_capabilities

What they can do right now and why not: the workspace they're in and who they register for, the Business subscription (status, renewal, days left), credits, WhatsApp, personal drafts, whether a registration can start in each workspace (and the tool that unblocks it), credit purchases, and features switched on for them.

Discovered
get_credits

Their credit balance, recent credit activity, Business subscription status, and the credit packs they can buy (pack_id for request_credit_purchase).

Discovered
get_nin_request_status

Where a request from start_nin_request stands: status (waiting_for_person, started, settling, verified, failed, expired, paid, delivered, delivery_failed), next_step in words, the products and their naira prices. Never the NIN or the person's details: those go only to the person.

Discovered
get_notification_preferences

How they get updates: in-app, email, WhatsApp, and WhatsApp tips and offers.

Discovered
get_prices

FastCAC's own current prices, live: business name registration (personal and agent workspace), the Business Pro subscription, annual returns (CAC's fee and ours, per year), credit packs, the NIN tools and the developer API. Use it for any question about what FastCAC charges, every time, instead of a price from memory, a page or the knowledge base.

Discovered
get_registration_state

Read where one of the user's registrations stands: status, stage, next action and action_path, which form sections are done, missing or invalid fields (names only), each document's status and what's wrong with it, payment status, whether their NIN is confirmed, and for a queried registration CAC's reason plus each flagged item with its fix_path and whether it's resolved. It never includes personal details (NIN, date of birth, phone, addresses); those are on the registration page.

Discovered
get_subscription

Their Business subscription: status (none, trialing, active, past_due...) and period end.

Discovered
list_my_businesses

List the signed-in user's businesses with each registration's stage, the next action, and action_path (the dashboard page for that action).

Discovered
list_nature_of_business

Browse CAC's Nature of Business list: with no category, its categories (id, name, how many entries); with a category's id or name, every Specific Nature of Business entry under it. An entry is the line of business a registration uses, exactly as written.

Discovered
list_notifications

Their recent notifications (unread only by default).

Discovered
list_share_links

A business's share links: the status link (anyone with it sees progress) and the details form link (the owner fills in their own details). Whether each is live, when it expires. Never the link itself.

Discovered
manage_subscription

Show a button to Paystack's page for changing their card or cancelling the subscription.

Discovered
mark_notifications_read

Mark all their notifications as read.

Discovered
recheck_documents

Run the checks again on documents that are stuck (e.g. the check service was down, or the NIN slip is waiting on the passport photo). Not for a document that failed - that needs a new upload.

Discovered
refresh_cac_status

Ask CAC now for the latest on a registration that's with them (submitted or queried). Changes arrive as system events too.

Discovered
remove_discount_code

Remove the discount code from a registration that isn't paid yet.

Discovered
remove_whatsapp

Remove their WhatsApp number. Shows a Confirm button first.

Discovered
rename_business

Rename a business (its display name; not allowed once CAC approved it).

Discovered
request_credit_purchase

Show a Pay button for a credit pack (Business plan subscribers). Use a pack_id from get_credits.

Discovered
request_documents

Show an Upload button for a registration's documents (passport photo, NIN slip, signature, and a supporting document if CAC's name check asked for one). Without document_types it asks for every required document still missing or failed; name document_types to ask for specific ones again (e.g. CAC queried the passport photo). Files never pass through you; each verdict arrives as a system event.

Discovered
request_nin

Show a secure NIN field for a business so the user can verify their identity. Their name, date of birth and gender are filled from it. The NIN is typed into that field, not into the conversation.

Discovered
request_payment

Show a Pay button for a registration once its form is complete. The amount comes from FastCAC's pricing (less any discount code applied). You never see card details or the payment link; the outcome arrives as a system event.

Discovered
request_subscription

Show a Start free trial button for the Business subscription (for people registering businesses for clients). 14 days free, set up on Paystack.

Discovered
request_whatsapp_verification

Show a Verify on WhatsApp button. Needed before starting a business or paying (create_business / request_payment return whatsapp_unverified).

Discovered
revoke_share_link

Turn off a business's share link. Shows a Confirm button first.

Discovered
search_cac_register

Search the Corporate Affairs Commission's (CAC) public register for businesses already registered in Nigeria, by name or by RC/BN number. Returns `results`: name, rc_number (the BN number for a business name), registration_date, classification, nature_of_business, status (e.g. ACTIVE or INACTIVE), company_id, classification_id and match (exact, close, similar or null), best match first; RC/BN numbers ("RC 8911267") are read as numbers. Lead with the result whose match is exact; when none is, say plainly that nothing is registered under that exact name before listing the closest. This lists what exists; it isn't an availability check (check_name_availability and check_business_name_compliance are). An `error` never means there's no match.

Discovered
search_knowledge_base

Search FastCAC's knowledge base: the articles, policies, guides and how-tos FastCAC's team has written (pricing and what it includes, refunds, timelines, documents, what happens after payment, CAC rules and procedures, post-registration steps). Use it before answering a question about FastCAC's service or CAC process that the instructions above don't settle, and answer from the passages, not memory. Returns passages best first, each with its document title, heading, updated_at, a 0-1 rank score and a 0-1 similarity (how close in meaning; about 0.7 and up answers the question), plus total_matches and has_more. Weak or no results: try mode 'broad', reword the query, or page on with offset. If it still has nothing, say plainly that you don't have that information.

Discovered
search_line_of_business

Find exact entries in CAC's line-of-business picklist matching what the business does.

Discovered
set_share_review

Turn on or off the 'review the details' section on a business's live status link.

Discovered
show_share_link

Show a Copy button for a business's live share link.

Discovered
start_nin_request

Start a paid request on fastcac.com for: 'slip' = the person's NIMC NIN slip (PDF and print-ready image), using their NIN; 'phone' = the person's NIN, found with the phone number they registered with NIMC (on fastcac.com they can add the slip; you can't request it here). Returns a link for the person and a request_handle for you. The person does a live face check and pays on fastcac.com (the prices are in get_nin_request_status's `products`, or get_prices); the result goes only to them. Starting is free and charges nothing.

Discovered
switch_workspace

Switch the dashboard between their Personal workspace (their own businesses) and the Business workspace (`agent`: businesses they register for clients; needs the Business subscription).

Discovered
update_notification_preferences

Turn update channels on or off. Only pass the ones they asked to change.

Discovered
update_profile

Change their account name (first and/or last name). Not a registration's proprietor name.

Discovered
update_registration_fields

Save registration form fields from what the user told you. Only these fields can be set: proposedOption1 (Proposed business name), lineOfBusiness (Line of business (exact CAC picklist entry)), proprietorPhonenumber (Phone number (digits only)), proprietorEmail (Email), proprietorState (State), proprietorLga (LGA), proprietorCity (City), proprietorStreetNumber (Street number), proprietorServiceAddress (Street name / address), proprietorPostcode (Postcode (digits only)), companyState (Company state), companyCity (Company city), companyStreetNumber (Company street number), companyAddress (Company street name / address), companyEmail (Company email). Returns what saved, anything invalid, and what's still missing.

Discovered
use_nin_photo_for_passport

Use the photo from their confirmed NIN record as the passport photograph instead of uploading one. Only after they agree, and only once their NIN is confirmed.
