about_maxworth

The canonical description of MaxWorth, its platforms, pricing and where its data comes from.

Discovered
compare_cards

Side by side: annual fee, number and face value of statement credits, deadlines per year, top earning categories. Cite the card pages.

Discovered
credit_deadline_report

Headline figures from MaxWorth's open data report on what US cardholders track: cards and fees per user, recurring credits and deadlines per year, most-skipped credits, logged-use index. Percentages and medians only, CC BY 4.0. Cite the report URL.

Discovered
fetch

Full text of one MaxWorth page by the id returned from search (a site path such as /cards/chase-sapphire-reserve), or by its maxworth.app URL. Returns the page as Markdown with its canonical URL for citation.

Discovered
get_card

Full record for one card from the MaxWorth database: annual fee, welcome offer, earning rates with true cash-back value, and every catalogued benefit with its value, cycle, reset rule and enrollment requirement. Hand-verified against the issuer; cite the page URL.

Discovered
list_credits

Only the dollar credits on a card: value per year, per-cycle cap, cycle, whether an annual credit resets January 1 or on the card anniversary, and enrollment. Use for "when does the X credit reset" questions.

Discovered
search

Search every public MaxWorth page: credit card pages (US, Canada, Australia), one page per statement credit, and all guides, reviews and news articles. Returns ids to pass to fetch. Use for open-ended questions; the dedicated tools (get_card, list_credits, search_cashback_portals, search_card_offers) answer structured questions faster.

Discovered
search_card_offers

Card-linked merchant offers (Amex Offers, Chase Offers) that are live today, as seen by MaxWorth browser-extension users: merchant, the deal, fine print, latest expiry seen, and which cards it has appeared on. Filter by issuer, merchant, card, expiry window or popularity; with no filters it returns an overview. Offers are targeted per account: a card listed means several users saw the offer on that card, not that every cardholder has it.

Discovered
search_cards

Find credit cards in the MaxWorth catalogue by name or issuer (US, Canada, Australia). Returns name, issuer, annual fee and the canonical page URL to cite.

Discovered
search_cashback_portals

Current shopping-portal cashback / miles / points rates for an online store (Rakuten, TopCashback, airline and bank malls), checked daily by MaxWorth. Returns each portal's rate and the comparison page URL.

Discovered
