Get your key
Free. Just your email: no password, no card. One key covers mail, fax, bookings, restaurant tables, shipping labels, photo prints, greeting cards, and signatures.
- Get your key here, with just your email.
- Paste one prompt into your AI agent: Muse, Claude, ChatGPT, Cursor or any MCP client.
- Paste the key into the agent's credential store when it asks (in Muse, the Secure Credentials Store).
Works with any AI agent. The steps below use Meta Muse as the example; any other agent takes the same prompt and the same key.
Your key is ready. Keep this page open until Muse has your key: it is shown once and we cannot show it again.
Step 1: paste this into Muse
Copy it, open Muse, and send it as one message. It is a normal setup message: it tells Muse where our instructions are, and to ask you before spending anything. Muse will show a notice that custom connectors are not reviewed by Meta; that is normal for every custom connector.
Build a custom connector for No Errands. One API key covers eight services: printed mail (letters and postcards), fax, appointment booking, asking a restaurant for a table, shipping labels, printing and posting photos, mailing greeting cards, and getting documents signed. 1. Read these eight connector briefs and follow them exactly: https://noerrands.com/connectors/muse.md https://noerrands.com/connectors/fax/muse.md https://noerrands.com/connectors/booking/muse.md https://noerrands.com/connectors/tables/muse.md https://noerrands.com/connectors/ship/muse.md https://noerrands.com/connectors/prints/muse.md https://noerrands.com/connectors/cards/muse.md https://noerrands.com/connectors/sign/muse.md 2. Store my API key in the Secure Credentials Store as NOERRANDS_API_KEY. The same key works for all eight. Never print, log, echo, or repeat it, not even partially. Send it as the header: Authorization: Bearer <NOERRANDS_API_KEY> 3. Prefer the MCP endpoints (streamable HTTP): https://api.noerrands.com/c/mail/mcp https://api.noerrands.com/c/fax/mcp https://api.noerrands.com/c/booking/mcp https://api.noerrands.com/c/tables/mcp https://api.noerrands.com/c/ship/mcp https://api.noerrands.com/c/prints/mcp https://api.noerrands.com/c/cards/mcp https://api.noerrands.com/c/sign/mcp If you use the REST APIs instead, each brief links its OpenAPI document. 4. Before you mail anything, fax anything, book anything, contact a restaurant, buy a shipping label, order prints, send a card, or send a document for signature, show me exactly what will happen, what it costs and who it goes to. Then wait for my explicit approval. Never act without asking me first. Signing links go out only from my own email, after I approve each message. 5. Save this as a reusable skill called "No Errands". 6. When it is set up, check it works by asking for my balance (free), then tell me in a few lines what I can ask you for. Offer to try it with something free: a document I sign myself (my first one is free) or a price quote for a letter. Do not spend my credits to test it.
Step 2: when Muse asks for your key, copy it from here
Copy this now. It is shown once and we cannot show it again. If you lose it, come back and get another one.
Paste it into Muse's Secure Credentials Store when Muse asks for it. Do not paste it into a chat message, a document, or an email. Anyone who has this key can spend your credits.
Store it in Muse under the name
NOERRANDS_API_KEY. Scope: .
Try it free right now
Your balance starts at $0.00, and these cost nothing. Say to Muse:
- "Send me a document to sign myself." Your first self-sign envelope is free.
- "How much would it cost to mail a one-page letter to my landlord?" Price quotes are free.
Add credits
When you want to mail something: a letter is $2.49, a postcard is $1.69 and a fax is $1.49, so add credits before your first send. You can buy $2.49 for a single letter, or $10.00 for $12.50 of credit (one free letter), $25.00 for $32.50 of credit (three free letters) and $50.00 for $67.50 of credit (seven free letters); every pack credits more than it costs. Booking an appointment is free and needs no credits.
You can also ask Muse for a top-up link at any time. It will hand you a checkout link; you pay in your own browser.
