No signup, no\nAPI key, no dashboard. An agent calls one endpoint, gets a `402 Payment Required` with an MPP `Payment`\nchallenge, pays in USDC.e on Tempo, and the fax goes out. It's \"AgentMail, but for faxes.\"\n\nPay it in one line with the Tempo CLI:\n\n```bash\ntempo request -X POST --json '{\"to\":\"+14155550123\",\"file_url\":\"https://example.com/doc.pdf\"}' \\\n https://agentfax.val.run/v1/fax\n```\n\n## Why it's interesting\n\n- **Permissionless monetization.** No marketplace to apply to. You stand up an HTTP endpoint that\n returns a 402 `WWW-Authenticate: Payment` challenge pointing at your wallet; any MPP client pays it.\n- **No facilitator, no keys to babysit.** `mppx` verifies and settles the payment directly against the\n Tempo chain — there's no payment processor in the middle.\n- **Stateless / zero data retention.** agentfax forwards the document to the fax network and keeps\n nothing — no DB, no logs of numbers or contents. The job id it returns is a thin pointer to the carrier.\n- **Pluggable fax backend.** Real faxing via [Phaxio](https://www.phaxio.com) when keys are set;\n otherwise a deterministic **sandbox** that simulates sending, so the whole pay→fax loop works with no\n fax account.\n\n## Endpoints\n\n| Method | Path | Paid | Description |\n|--------|------|------|-------------|\n| `POST` | `/v1/fax` | ✅ MPP | Send a fax. Returns `402` (MPP `Payment` challenge) until paid, then a job id. |\n| `GET` | `/v1/fax/{id}` | free | Live delivery status (proxied from the carrier). |\n| `GET` | `/v1/info` | free | Machine-readable manifest (price, network, recipient, schema, example). |\n| `GET` | `/llms.txt` | free | Pointer file so an agent can self-onboard. |\n\n### Send a fax\n\n`to` is required (E.164). Provide the document as either `file_url` (a public PDF URL) or\n`content_base64` (+ optional `file_name`). `metadata` is optional, echoed back, not stored.\n\nUnpaid, `POST /v1/fax` returns `402` with a `WWW-Authenticate: Payment` header. The Tempo CLI (or any\nMPP client) reads it, signs the USDC.e payment, and retries automatically.\n\n## Payments\n\n- **Rail:** MPP (the open `Payment` HTTP-auth scheme) on **Tempo mainnet** (chain id 4217).\n- **Asset:** USDC.e — `0x20C000000000000000000000b9537d11c60E8b50` (6 decimals).\n- **Settlement:** verified directly against the Tempo RPC by `mppx` — no facilitator.\n- **You get paid** at `TEMPO_RECIPIENT` (your Tempo wallet).\n- **x402 (Coinbase/Circle) is parked** in the codebase (`payment.ts`); re-enable it with a valid CDP\n facilitator key to also accept Base USDC agents.\n\n## Configuration\n\nSensible defaults; the only thing you must set for real money is funding your wallet.\n\n| Env var | Default | Purpose |\n|---------|---------|---------|\n| `TEMPO_RECIPIENT` | Steve's Tempo wallet | Tempo address that **receives** the USDC.e. |\n| `MPP_SECRET_KEY` | (set) | Server HMAC secret binding challenges to credentials. |\n| `MPP_SIGNER_KEY` | (set) | Server signer required by `mppx` (session settlement; unused by one-shot charge). |\n| `FAX_PRICE_USD` | `0.50` | Price per fax. |\n| `PHAXIO_API_KEY` / `PHAXIO_SECRET` | unset → sandbox | Enable real faxing via Phaxio. |\n\n### Go live (real faxes + real payments)\n\n1. **Fund your Tempo wallet** with a little USDC.e (`tempo wallet fund`) — that's where payments are\n debited from when *you* test, and the recipient of inbound payments.\n2. **Add Phaxio keys** so faxes actually transmit (otherwise sandbox-simulated):\n\n 👉 Add PHAXIO_API_KEY here: https://www.val.town/x/stevekrouse/agentfax/environment-variables?key=PHAXIO_API_KEY\n\n 👉 Add PHAXIO_SECRET here: https://www.val.town/x/stevekrouse/agentfax/environment-variables?key=PHAXIO_SECRET\n\n## Files\n\n- `main.ts` — Hono server: routes, MPP payment gate, SSR landing page.\n- `mpp.ts` — Tempo/MPP rail via `mppx` (mainnet, USDC.e), `paymentInfo()`.\n- `fax.ts` — stateless fax backend (Phaxio + sandbox), job-id codec, live status.\n- `payment.ts` — parked x402 rail (re-enable with a CDP key).\n- `frontend/` — SSR React + Twind landing page.\n\nBuilt on [Val Town](https://val.town).
