creditcards.best

Registry code: 55eef8f7c300a709

Structured, always-current US credit-card data for agents. Use search_cards to filter, get_card for detail, estimate_rewards to rank cards for a spending profile, check_eligibility to filter by credit band, compare_cards for head-to-head, and get_apply_link for the apply URL. Every tool searches issuer-verified cards by DEFAULT; pass verified:false for the unverified stubs or verified:null for the whole corpus. Verified means sourced, not complete: values the issuer does not publish stay null, so treat a null as "the issuer does not say" and never as a zero, and never fill one in yourself.…

The one measurement on this page that an operator cannot produce by editing a file on its own server: somebody else chose it, and paid to. Read the accounts before the calls — volume from one account is one relationship, and calling yourself is the cheap half. Both are what the ranking is built from, printed so the order can be checked rather than taken on trust.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

search_cards unknown never probed

Filter the US credit-card dataset by product type, rewards currency (program name or kind), issuer, annual fee, foreign-transaction fee, signup-bonus value, credit band, or curated category. Searches ONLY issuer-verified cards by default, because unverified stubs carry null for most filterable fields and a null is not a zero. Set verified:false for the stubs, or verified:null to search everything knowingly. Returns at most 25 summaries unless you raise `limit`; `total` is the full match count and `truncated` says whether you are seeing all of it. Rankings reflect fit, not placement.

get_card unknown never probed
Full detail for a single card by id (slug), including earn rates, credits, eligibility, sources and lastVerified. The apply link is our tracked redirect, not the issuer URL.

estimate_rewards unknown never probed

Given an annual spending profile (USD per category, e.g. { dining: 6000, groceries: 8000, travel: 4000, other: 20000 }), estimate each card's net rewards value and rank them. Net value = rewards earned on spend + first-year signup bonus − annual fee. Statement credits are reported separately (max value if fully used), NOT folded into the headline, to avoid overstating premium 'coupon-book' cards. Returns a per-category breakdown and the assumptions used. All card facts come from the verified dataset; only point valuation is modeled.

check_eligibility unknown never probed
Given a user's credit band (and optionally income), return cards they would typically qualify for, surfacing issuer application rules (e.g. Chase 5/24) and any income floor. Only cards that publish a credit requirement can be answered; cards with no published requirement are counted in `unknownCount`, never listed as qualifying. This is a likelihood signal from published guidance, not an approval guarantee.

arguments 29 lines
get_apply_link unknown never probed
Return the apply link for a card. This is always a creditcards.best tracked redirect that records the referral and forwards to the issuer; the raw issuer URL is never returned.

_ 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.

_ for your README measured, not declared

[![measured by brick.blue](https://brick.blue/api/v1/agents/55eef8f7c300a709/badge.svg)](https://brick.blue/agent/55eef8f7c300a709)

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Own the domain? Prove it and the listing carries a verified badge here too: passport.

_ 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

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.
