--- title: "Everyone gets an app" url: https://services.dev/docs/start/participants captured: [tax-who.txt] --- # Everyone gets an app URL: https://services.dev/docs/start/participants > Who takes part in a job is worked out from your Service, never declared, and each of them gets the app and the calls their part needs. You never list who takes part in a job. `check` reads it off your Service: who orders it, who the work is for, who acts at each step, and who runs the business. Each of them gets an app, and each app shows only the calls their part allows. ## Derived, never declared Translation, as `npx services.dev` writes it, has no person in it, so `check` finds two apps: ```txt $ npx services.dev check services/translation.ts · 4 lines · $49 per job, within 48 hours, charged on delivery. who AI delivers every job. steps draft · ai → review · ai · adversarial agent order_translation · 24 of 30 words · bought job_7Hq2 · $49.00 · no person ledger +$49.00 · AI $0.84 (example) · you $48.16 margin at least $39.20 a job (80%) · a job that stops costs you at most $9.80 apps customer portal · owner console ``` [Grow it](https://services.dev/docs/grow/role.md) with a question for the buyer and a sworn translator's signature, and the third app appears.

You and two staff sign on Free, with a role and no `pool`.

This table is generated from the credential and operation registries: | Who | Holds | Can | Operations | Reaches | A person? | |---|---|---|---|---|---| | a buyer | secret key, test mode, `sk_test_` | order, read, accept, send back, cancel, end, watch, and run test clocks | 37 | http, cli, mcp, sdk | | | a buyer | secret key, `sk_live_` | order, read, accept, send back, cancel, end, watch | 35 | http, cli, mcp, sdk | | | an agent a party delegated, scoped by Service and time | delegated key, `dlg_` | order within its cap; complete answer and upload asks; read that party's jobs | 31 | http, mcp, sdk | | | the named party, with no account | party link | complete that one ask, once | 4 | http | yes | | a member, in the delivery portal or the member CLI | member session | every member act: join, set availability, keep their conflicts ledger, read their feed, claim, clear and do a Task | 30 | http, cli | yes | | an integrator, with On-Behalf-Of | tenant key, `tk_` | order for its customer; read with consent | 17 | http, sdk | | | the owner and staff roles | owner session | the console, staff acts | 34 | http, cli | yes | | a Pool's or the brand's verifier | verifier token, `vt_` | write verified facts | 1 | http | | | a watch | webhook secret, `whsec_` | verify deliveries | 0 | sdk | | | anyone | no key | `service.quote`, `service.waitlist`, `service.list`, `service.get`, `key.create`, `brand.home`, `brand.health`, `sandbox.fixtures`, `brand.card`, `brand.openapi`, `brand.llms`, `brand.manifest`, `brand.pricing`, `brand.verify` | 14 | http | | ## What only a person does A key can order, wait, accept and send back, so an agent can buy a whole job. Some acts need the person themselves: signing, consenting, directing, deciding and approving. Those take a person's own session or the link their ask carries, and they are never an MCP tool. An agent that reaches one gets the link first in `next`, to hand to the person it asks, and the calls it can still make: ```txt → tools/call get_job {"id":"job_7Hq2","wait":50} # the text an agent reads first, beside structuredContent ← job_7Hq2 · waiting · on party · $49.00 held next hand http://localhost:8787/a/ask_7Hq2?t=8FaWT5EoCj4h-uMyjlXp3_ to the person it asks next get_job {"id":"job_7Hq2"} next cancel_job {"id":"job_7Hq2"} ``` If it tries to finish the job itself, the answer is `needs_the_party`, with the same link. So a person keeps every act that is theirs, and an agent still does everything else. ## Next **[Choose your shape](https://services.dev/docs/start/shapes.md)**: the reference Service that looks like yours, what each job leaves you, and the plans it climbs. --- - Up: [Your first paid job](https://services.dev/docs.md) - Previous: [How a job runs](https://services.dev/docs/start/how-it-runs.md) - Next: [Choose your shape](https://services.dev/docs/start/shapes.md)
