api record

earnrate answers which credit card earns the most for a purchase, from each issuer's own terms. Anyone can use it without entering anything: with no cards given, best_card_for_purchase, best_cards_for, cheat_sheet, simulate_spending and compare_welcome_offers answer from every card earnrate knows, and that's a complete answer. Never require the user's cards, and don't ask what they spend unless the answer depends on it; simulate_spending assumes typical amounts when none are given and says so.

Personalizing is optional. If the user names their cards, pass them as `cards` (ids from…

  • cheat_sheet open 55m ago

    The card to use for each everyday kind of purchase right now: groceries, dining, gas, Amazon, Costco, travel, streaming, drugstores and everything else. With no cards given and no saved wallet, it picks from every card earnrate knows (`scope: all cards`, each row noting the card's fee and conditions). With cards named in the conversation or a saved wallet, it picks from the user's own cards, with caps, picks and activations as they are. For one specific store, call best_card_for_purchase instead. Pass on the notes.

  • compare_welcome_offers open 55m ago

    Ranks the public welcome (sign-up) offers on cards the user doesn't have by first-year value: the bonus at the user's point values minus the first year's annual fee. Use it when the user asks which new card to get or which has the best sign-up bonus. It covers only the cards earnrate knows, offers vary by person, and each offer's note gives the issuer's eligibility rules; pass those caveats on. It doesn't account for what a card would earn on the user's spending.

  • best_card_for_purchase unknown never probed

    Which card earns the most rewards for a purchase, and why. With no cards given and no saved wallet, it ranks every card earnrate knows (in `allCards`): a complete answer for anyone. With cards named in the conversation (`cards`) or a saved wallet, it picks the best of the user's own: `decision.cardId` is the pick and `decision.checkoutLabel` is how the card appears at checkout, with every usable card ranked with reasons, cards the merchant won't take, assumptions, warnings, and when a different point valuation would change the pick. Never needs or returns card numbers.

  • simulate_spending unknown never probed

    Spends monthly amounts for a year across every card earnrate knows, and ranks single cards and two-card pairs by rewards minus annual fees. Spending is optional: without it, typical U.S. household amounts are used and the answer says so. With `cards` (named in the conversation) or compareToWallet (the saved wallet), it ranks the cards that would add the most to those cards instead. Use it for "which card fits my spending?" or "is it worth adding a card?". It leaves out welcome bonuses.

Returns each card's id (for add_card), network, annual fee, whether it's already in the wallet, and what it needs set up: category picks and their options, memberships, activations. Leave the query out to list every card. US cards only.

    Lists the user's cards: checkout label, network, rewards currency and its value, spending caps with how much is left this period, chosen bonus categories (and whether they're current), welcome-bonus progress, which stores a store card works at, and when each card's data was last verified.

    Records a purchase the user has already made, so spending caps and welcome-bonus progress stay accurate for future recommendations. It updates the user's saved wallet. Only call it after the purchase has happened, and only once per purchase: calling it twice counts the spend twice. Purchases with no cap and no open welcome bonus are acknowledged and nothing is written.

  • import_wallet unknown never probed

    Replaces the saved wallet with a wallet.yaml from the earnrate command line or earnrate.dev, when the user pastes or attaches one. Wallet files only: never statements or card numbers. Confirm with the user first if they already have cards saved.

  • best_cards_for unknown 55m ago

    Ranks every card earnrate knows, not only the user's, for one purchase or category, each set up at its best (the right category pick, activated, cap unused), with its annual fee and what earning the rate takes. Use it for questions like "what's the best card for groceries?" or "which card should I get for Amazon?". It needs no wallet. For which of the user's own cards to use, call best_card_for_purchase instead. Mention the annual fee and any conditions alongside each card.

_ try it through the hub, ceiling 0

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.

_ is this your agent? claim it: badge, payouts, history

Nobody has claimed this listing. Claimed, its README badge says «verified owner» with figures this hub measured, routed paid calls to it pay your account (today there is nobody to pay), and its history counts towards your passport.

  1. Sign any request with an ed25519 key — that binds it: GET /api/v1/me, then POST /api/v1/passport.
  2. Prove it is yours. Easiest: put brick-blue-key=<your key> in your MCP server's instructions — or a DNS TXT record / a file on the domain.
  3. Ask the hub to check: POST /api/v1/passport/claim-endpoint with this listing's id a4da032e9d9bbd5a.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/a4da032e9d9bbd5a/claim. Over MCP: the claim_endpoint tool.

_ for your README measured, not declared

measured by brick.blue

[![measured by brick.blue](https://brick.blue/api/v1/agents/a4da032e9d9bbd5a/badge.svg)](https://brick.blue/agent/a4da032e9d9bbd5a?ref=badge)

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Unclaimed, it says so; claim the listing and the same badge says «verified owner» with its uptime and paid calls.

_ how we know
card completeness
100%

An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.

spec deviations
0

MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.

_ record

Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
