5## Requirements6
7- Node.js 20+8- [Apify CLI](https://docs.apify.com/cli) for deployment9
10## Scripts11
12```bash13npm install14npm run build # compile TypeScript to dist/15npm run lint # ESLint (src and test)16npm run format # Prettier17npm test # unit + end-to-end tests (node:test)18npm start # run locally with tsx19```20
21## Credentials22
23The Actor uses our Tomba account. Credentials come from environment variables, never from the input:24
25| Variable | Description |26| -------------------- | -------------------------------------------------- |27| `TOMBA_API_KEY` | Tomba API key (`ta_…`) |28| `TOMBA_API_SECRET` | Tomba secret (`ts_…`) |29| `TOMBA_API_ENDPOINT` | Optional API base URL; only used by the test suite |3031`.actor/actor.json` maps the variables to Apify secrets:32
33```bash34apify secrets add tombaApiKey ta_xxxxxxxxxxxxxxxxxxxx35apify secrets add tombaApiSecret ts_xxxxxxxxxxxxxxxxxxxx36apify push37```38
39When deploying from a linked Git repository instead, add `TOMBA_API_KEY` and `TOMBA_API_SECRET` as secret environment variables in the Actor settings.40
41Run locally:42
43```bash44TOMBA_API_KEY=ta_… TOMBA_API_SECRET=ts_… npm start45```46
47## Pricing (pay per event)48
49In **Apify Console → Publication → Monetization**, choose **Pay per event** and add:50
51| Event | Price | Charged when |52| --------------- | -------- | --------------------------------------------- |53| `tomba-request` | $0.00312 | Tomba returns a billable response (see below) |5455Author Finder costs 1 credit per billable URL (one `tomba-request` event); the item's `chargedCredits` is `res.chargedCount` (1, or 0 when not charged or cached). `webhookUrl` does not change the price.56
57`isBillable()` in `src/tomba.ts` mirrors Tomba's billing:58
59| Tomba outcome | Charged |60| ------------------------------------------------------------------ | ------- |61| JSON with non-empty `data`, including an author with `email: null` | Yes |62| Error status (4xx, 5xx, including 422 and 429) | No |63| Success with empty or null `data` | No |64| Success with an `errors` object | No |65| Non-JSON body (reported as 502) | No |66| Cache hit | No |6768## Architecture69
70- `src/tomba.ts`: shared helper, identical in every Tomba Actor. It handles credentials, caching (per-Actor `tomba-cache-<actorId>` key-value store; falls back to an in-run cache if it can't be opened), retries with exponential backoff, pay-per-event charging, budget reservation, the concurrency pool and resume state.71- `src/main.ts`: trims and deduplicates `urls`, limits them to `maxResults`, calls `GET /author-finder?url=…` (`Finder.authorFinder(url, webhook_url)`) for each one and pushes one item per URL: the Tomba `data` object plus `input_url`, `source`, `chargedCredits`, `charged` and `cached`, or an `error` item with `email: null` and `chargedCredits: 0` when nothing billable came back. `webhook_url` is only sent when `webhookUrl` is non-blank and is part of the cache key.72- The `tomba` SDK v1.1.1 resolves every call to `{ data, rateLimit }`, where `data` is the response body. Its `.d.ts` types still declare the old return type, so always go through `callTomba()`.73
74## Tests75
76- `test/tomba.test.ts`: unit tests for the shared helper (identical in every Actor)77- `test/main.test.ts`: end-to-end tests that run `src/main.ts` against a local mock Tomba API78- `test/helpers.ts`: mock server and Actor runner (identical in every Actor)79
80Locally, the Apify SDK prices every event at $1 when `ACTOR_TEST_PAY_PER_EVENT=true`, so the tests use `maxTotalChargeUsd` as an event count.81
82## Standby mode (real-time API)83
84`.actor/actor.json` sets `usesStandbyMode: true` and `webServerSchema: ./web_server_schema.json` (OpenAPI 3).85
86- `src/standby.ts` (shared, identical in every Actor): `runActor()` runs a batch job, or, when `APIFY_META_ORIGIN=STANDBY`, starts an HTTP server on `Actor.config.get('containerPort')`.87 - `GET /` with the `x-apify-container-server-readiness-probe` header, or with no query: readiness / usage.88 - `GET /?…`: input built by `fromQuery()` from `url` / `urls` (repeated or comma-separated, so URLs containing commas need `POST`), `webhookUrl` and `maxResults`.89 - `POST /`: the same JSON input as a batch run.90 - Responses: `200 { items }`, `400` invalid input, `402` max charge limit reached, `404`, `405`.91- `run(input, ctx)` in `src/main.ts` is shared by both modes: `ctx.push()` writes to the dataset in batch runs and to the HTTP response in Standby; `ctx.isDone()`/`ctx.markDone()` persist resume state only in batch runs. Input errors throw `InputError` (failed run in batch, `400` in Standby).92- Caching and pay-per-event charging work the same in both modes.93
94Try it locally:95
96```bash97APIFY_META_ORIGIN=STANDBY ACTOR_WEB_SERVER_PORT=8080 TOMBA_API_KEY=ta_… TOMBA_API_SECRET=ts_… npm start98curl "localhost:8080/?url=https%3A%2F%2Fwww.shopify.com%2Fblog%2Fself-publish-a-book"99```100
101## Key-value store schema102
103`.actor/key_value_store_schema.json` documents the default key-value store records (`INPUT`, `TOMBA_STATE`). The cross-run cache lives in the separate named store `tomba-cache-<actorId>`, one per Actor: under limited permissions an Actor can only open named storages it created itself, so the Tomba Actors must not share one store. If the store can't be opened, the run logs a warning and caches for this run only.104
105## Memory106
107`defaultMemoryMbytes` is 256: the Actor only makes HTTP calls, so more memory just costs more.{ "extends": "./tsconfig.json", "compilerOptions": { "noEmit": true }, "include": ["./src/**/*", "./test/**/*"]}# configurations.idea.vscode.zed
