Nothing serious here today

Today is the operative word: we check Market every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.

hekte

hekte_ask

Buy one answer on the Hekte market — PAY FIRST, per call, Lightning. Call it with `prompt` alone: the result is an error with `status: "payment_required"`, a Lightning `invoice` (bolt11) for `amount_sat` (whole sats), a `pay_url` a human can open, an `expires_at`, and `retry_with` (`payment_hash`, `retry_token`). Show the human the `pay_url` (or the invoice) and ask them to pay it; then call this tool AGAIN with the SAME `prompt` and `class` plus the `payment_hash` and `retry_token`. Before the payment arrives the retry answers `payment_not_received`; after it, the question is posted as a paid job, a worker answers, the payment settles ON DELIVERY and the answer comes back with who served it and a `receipt`. If nothing is delivered the hold is cancelled (`hold_cancelled: true`) and nothing is charged. No balance is kept, no account exists: one invoice is one call. Refused by name: `prompt_too_large` (over 16384 bytes), `class_unknown`, `invalid_max_sat`, `proof_unknown`, `proof_expired`, `proof_replayed`, `proof_cancelled`, `retry_token_invalid` (the token is not this invoice's), `request_mismatch` (a retry must repeat the paid prompt), `contract_mismatch` (the `contract` named is not 2, this door's).

hekte_balance

The PRICE of the next `hekte_ask` on this pay-first door: `price_sat` (whole sats, Lightning, per call), `invoice_expiry_s` (how long a minted invoice can be paid), `pay_first: true`, and `open` (whether the door can buy on the market right now). No balance exists here — every call is its own invoice.

hekte_job

One job's lines from this door's BUYER LEDGER (posted, offers, funding, delivery, settlement — ids, sats, times, codes; never the brief or the output), for a job YOUR payment ran: `job_id` must be the one `hekte_ask` returned for this `payment_hash` + `retry_token`. `found: false` = no line names it.

Market — questions

Answers built from our own checks of this server.

What can Market do?

It exposes 3 tools, read directly from the server on our last check. Among them: hekte_ask, hekte_balance, hekte_job. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

Is Market working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 92 of 92 checks got a reply (100.0%), average response time 437 ms. The bar chart above shows every period we have measured.

How do I connect Market?

Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does Market need an API key?

No. Market completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 3 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is Market?

It answers our handshake in 437 ms on average, which is faster than 34% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
