PlaceCall - give your agent a phone ☎️

Two API endpoints: one finds who to call, one places a real phone call. Hand POST /calls a number and a plain-English task; PlaceCall dials it, talks to whoever answers, works through menus/hold, and returns a structured result + full transcript. No number yet? POST /v1/places/suggest turns "book a romantic restaurant in Chicago Saturday 8pm" into ready-to-dial place cards - phone, reasoning, and a ready-made call brief. It's how your agent reaches the ~80% of businesses that have a phone, not an API - inquiries, booking, lead-gen, appointment-setting.

curl -s -X POST https://api.voygr.tech/calls \

  -H "X-Client-Surface: gh-repo" \
  -H "X-Client-Agent: ${CLAUDECODE:+claude-code}${CURSOR_AGENT:+cursor}${CODEX_SANDBOX:+codex}${GEMINI_CLI:+gemini-cli}" \
  -d '{"target_phone":"+1XXXXXXXXXX","brief":"Call this restaurant and ask what time the kitchen closes tonight.","language":"en"}'

Install

Installing the skill needs no key - it just teaches your agent how to call the API. You add your key separately (next section) before placing real calls.

Claude Code (recommended)

Two commands, no shell, no git - and it auto-updates from this repo:

/plugin marketplace add voygr-tech/placecall
/plugin install placecall@placecall

Claude Code asks where to install it - choose user scope ("Install for you") unless you specifically want it confined to one repository. The skill then answers to /placecall:call, and Claude reaches for it on its own whenever you ask to call someone.

Claude Code, without the plugin

git clone https://github.com/voygr-tech/placecall && cd placecall
./install.sh     # copies skills/call/SKILL.md -> ~/.claude/skills/placecall/

install.sh is a tiny convenience script - it only copies skills/call/SKILL.md into your skills dir (no network, no other side effects); you can also copy it by hand. Then start a fresh Claude Code session (skills load at startup). Note that a copy never updates itself - if you want new skills and fixes as we ship them, prefer the plugin above.

Cowork

Same package as the Claude Code plugin, no terminal at all:

1. Customize > Plugins > Add marketplace
2. Paste voygr-tech/placecall
3. Click Install on the PlaceCall card

Auto-updates from this repo, like the Code plugin.

Then do both of these, in ~/.claude/settings.json. Cowork has no terminal, so the export in the next section has nothing to run in, and the Bash sandbox blocks our API until you allow it:

{
  "env": { "PLACECALL_API_KEY": "<your key>" },
  "sandbox": { "network": { "allowedDomains": ["api.voygr.tech"] } }
}

Restart Cowork afterwards. Why each half matters:

• env puts the key somewhere that survives a reboot. Setting it in a shell does not reach a desktop app, which never sees that shell.
• allowedDomains pre-allows api.voygr.tech. Claude Code pre-allows no domains, so without this you get a permission prompt on the first call, and if your organisation sets strictAllowlist or allowManagedDomainsOnly the call is blocked outright with no prompt. That is the "deep admin setting" people hit.

Your key sits in plaintext in that file, same trust level as the 600 env file in the next section. chmod 600 ~/.claude/settings.json if you want the file permissions to match.

Not claude.ai Chat. Plugins reach Claude Code and Cowork. They do not add anything to Claude chat conversations. The API is still just HTTP, so any agent with a shell can use it (see "Any agent / plain shell" below).

Codex

Type this inside Codex, not in your shell. $skill-installer is a system skill bundled with Codex, so there is nothing to set up first:

$skill-installer install the skill at https://github.com/voygr-tech/placecall/tree/main/skills/call and name it placecall

It is a skill rather than a command, so plain English works and is what it expects. It runs the install for you and reports where the skill landed. No restart needed, it is available on your next turn, and it answers to $placecall.

If the phrasing above is not understood, this is the script it runs, and you can run it yourself from a normal shell:

python3 ~/.codex/skills/.system/skill-installer/scripts/install-skill-from-github.py \
  --url https://github.com/voygr-tech/placecall/tree/main/skills/call \
  --name placecall

Two things worth knowing. The installer refuses to overwrite, so if you already have a placecall (or older callwright) skill in ~/.codex/skills, delete it first or the install aborts. And don't run install.sh on Codex, that is the Claude Code path.

On older Codex without $skill-installer, or as an alternative on any Codex, paste this repo's AGENTS.md into your project's AGENTS.md.

Any agent / plain shell

No install needed - the API is just HTTP. skills/call/SKILL.md is the full reference; a model with a shell tool can place calls straight from it.

Get a key (self-serve) and set it

Installing the skill does not need a key; placing calls does. Keys are self-serve - no need to contact anyone:

1. Open https://api.voygr.tech/checkout?src=gh-repo and click "Get free API key" (name + email).
2. The key arrives by email (it is never shown in the browser or API response). What a new key includes, and the current credit rates, are shown on the checkout page.
3. Lost the key? https://api.voygr.tech/recover emails you a new one.
4. Need more credits? Top up on the same https://api.voygr.tech/checkout?src=gh-repo page (Stripe-hosted payment).

Then set the key in your shell:

Quick way - just export it for the current session:

export PLACECALL_API_KEY="<your key>"

Nicer way - save it once (no echo to screen, 600 perms) and load it per session:

mkdir -p ~/.codex
read -rsp "PLACECALL_API_KEY: " KEY; echo
printf 'export PLACECALL_API_KEY=%q\n' "$KEY" > ~/.codex/placecall.env
chmod 600 ~/.codex/placecall.env
unset KEY
# then, in any new shell where you want to place calls:
source ~/.codex/placecall.env

No shell at all? A desktop app never sees your shell environment, so neither of the above reaches it. Put the key in the env block of ~/.claude/settings.json instead, which survives restarts. See the Cowork section, which also covers the sandbox domain allowlist you need there.

Verify (prints your quota, never the key):

curl -s -H "X-API-Key: $PLACECALL_API_KEY" https://api.voygr.tech/users/me

Never commit ~/.codex/placecall.env or paste the key into chat - keep it in the env var / the 600 file above.

Installed this before August 2026?

This project was called Callwright until 2026-08, and the repo lived at voygr-tech/callwright-skill. Two things to know:

• Your existing setup keeps working. install.sh copies the skill rather than linking it, so an older copy is frozen at whatever it was when you installed - the rename cannot break it. It also means it will never pick up new skills or fixes, which is the reason to migrate.
• To migrate, delete the old copy first. It is still a working phone skill, so leaving it in place gives your agent two of them and the routing between them is ambiguous. install.sh now warns you if it finds one.
  copy

  rm -rf ~/.claude/skills/callwright ~/.claude/skills/callwright-skill
  

  Then install the plugin above, and re-export your key under its new name: PLACECALL_API_KEY. The key itself is unchanged - only the variable is renamed, so no need to reissue anything.

If you previously installed a phone-call skill from someone else (e.g. ai-call-agent), remove or disable that too, for the same reason.

The one rule

Everything goes in the brief - the bot reads only your brief. Put every detail in it (what to ask, who you're calling for, names/dates/party size/callback number, how to wrap up). One endpoint, describe the task, done.

Good to know

• Two things draw on one credit balance: answered calls and answered place suggestions. Calls: only successful ones are billed — voicemails, hangups and no-answers cost nothing. Suggestions: 5 credits per answered POST /v1/places/suggest, nothing when it returns no cards or is refused. Both take a refundable hold at request time that is larger than the charge, so either can return 402 while your balance still looks sufficient for the charge alone (GET /users/me for your balance; rates and top-ups are self-serve at https://api.voygr.tech/checkout?src=gh-repo). The free tier is one shared pot: 250 free calls means 2,500 credits, and suggestions spend from the same 2,500.
• After a call completed, the outcome/transcript can populate a moment after the status flips - poll GET /calls/{id} until outcome_type is non-null.
• 13 language codes accepted (en, es, fr, de, hi, ru, pt, ja, it, nl, sr, tr, pl) plus auto (the default, resolves to en). en is the most reliable; non-English is best-effort.
• Only call numbers you're authorized to - real calls ring real phones. US destinations only; every call discloses it's a recorded AI call.
