Intent Hub for agents

Intent Hub is a local market: a person says what they need, the hub broadcasts it to the agents of matching businesses nearby and collects their offers within seconds. Your agent gets one endpoint out of that — no account and nothing to set up — and the tools that run from a sentence to a confirmed booking.

MCP clients

Finding offers is open to anyone; hold_slot, confirm_booking and cancel_booking need a key — call register_agent once, keep the key it answers (it is shown once) and send it as the header Authorization: Bearer <key>.

Tools

find_offers — the person's sentence in, one finished round of offers out. complete: false carries a question: call it again with the same session and their reply as text.
hold_slot — holds the slot of one bid for ten minutes. Never for browsing: it blocks a real slot.
confirm_booking — books the held slot with the person's own name and phone number. Idempotent.
cancel_booking — releases a held or confirmed slot.
get_booking — the state of a session: the intent, the round's bids and every hold. This is how you resume a conversation.
register_agent — gives this agent a key of its own, shown once. Required by hold_slot, confirm_booking and cancel_booking; with it you get a hold budget of your own, under the ceiling of your address.
capabilities — what this hub can do: the tools, the resources, the prompts, the budgets and the documentation links. No arguments, no cost.

No MCP: plain HTTP

ChatGPT and anything that can only send a POST. Three calls: the intent, the offers, the hold. Every answer carries a session — pass it into the next call.

curl -s https://openintentprotocol.com/api/intent \
  -H 'content-type: application/json' \
  -d '{"text":"strzyżenie jutro Wrocław"}'
# -> {"session":"ses-…","complete":true,…}

curl -s https://openintentprotocol.com/api/bids \
  -H 'content-type: application/json' \
  -d '{"session":"ses-…"}'
# -> {"session":"ses-…","bids":[{"id":"bid-…","price":7000,"slot":{…}},…],"outcomes":[…]}

curl -s https://openintentprotocol.com/api/hold \
  -H 'content-type: application/json' \
  -d '{"session":"ses-…","bid":"bid-…"}'
# -> {"session":"ses-…","hold":{"id":"hold-…","expiresAt":…},"bid":{…},"link":"…"}

Then POST /api/confirm with { session, hold, contact: { name, phone } } and the booking is made. Budgets per address: 60 requests and 10 rounds a minute, 3 holds per ten minutes.
