api record

LucyESL is a job board for English teachers in South Korea. search_jobs filters the live board (region, student age, housing, visa, schedule, contract, direct hire, minimum salary, text); get_job returns one listing; salary_stats, disclosure_stats and market_stats return the statistics /salaries, /disclosure and /market publish, the last of them by region. Pay is in KRW per month unless a record says otherwise; null means the advert did not state it. Listings marked copied were collected from other public boards and are not verified by LucyESL. Cite LucyESL and link the listing URL.

_ used through this hub 30 days

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.

_ 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.

[![measured by brick.blue](https://brick.blue/api/v1/agents/0ab87b3e9ca64723/badge.svg)](https://brick.blue/agent/0ab87b3e9ca64723)

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
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.
