When a server responds with [`402 Payment Required`](https://mpp.dev/protocol/http-402), `tempo request` reads the [challenge](https://mpp.dev/protocol/challenges), signs and submits the payment onchain, then retries with the [credential](https://mpp.dev/protocol/credentials) — all in one command. Requires [`tempo wallet login`](/docs/cli/wallet) first. ## Usage | Command | Description | | --- | --- | | `tempo request ` | Make an HTTP request with automatic payment | | `tempo request --dry-run ` | Preview cost without executing payment | | `tempo request -X POST --json '{...}'` | Send a JSON body | | `tempo request -H 'Header: Value'` | Add a custom header | ## Flags | Flag | Description | | --- | --- | | `-X ` | HTTP method (`GET`, `POST`, etc.) | | `--json ` | Send a JSON body (implies `-X POST`) | | `-H

` | Add a custom header | | `--dry-run` | Preview the payment cost and validate the request without spending | | `-t` / `--toon-output` | Compact machine-readable output for scripts and agents | ## Examples Preview cost before paying: ```bash tempo request --dry-run -X POST \ --json '{"prompt":"a sunset over the ocean"}' \ https://fal.mpp.tempo.xyz/fal-ai/flux/dev ``` Execute a paid request: ```bash tempo request -X POST \ --json '{"prompt":"a sunset over the ocean"}' \ https://fal.mpp.tempo.xyz/fal-ai/flux/dev ``` Discover the right URL and request schema first with [`tempo wallet services`](/docs/cli/wallet#service-discovery). ## Learn more
