Create a new mock REST API project. Returns {id, adminKey, baseUrl, resources[]}. SAVE the adminKey — it is required for admin operations (add_resource, custom_route, snapshots) and is shown only once…
Create a live mock API from existing artifacts. Auto-detects: OpenAPI 3.x / Swagger 2.0 spec (JSON or YAML) → resources with realistic seeded data, and non-CRUD paths (login, /search, RPC verbs like P…
Copy an entire project — resources + records verbatim, custom routes, behavior settings — into a brand-new project with its own id + adminKey. Built for parallel eval/CI runs: keep a template project,…
Add a resource (collection) to a project and seed it with realistic fake data. Either pass template (one of the built-ins, e.g. users, products, posts, comments, orders, todos, reviews, customers, eve…
Get a project's public root index: every resource with record counts and URLs, custom routes, auth mode, and export links (openapi.json, types.ts, postman.json, db.json, GraphQL). No adminKey needed. …
GET records from a mock resource. params is an object of query parameters, all optional: exact filters (field=value), operator suffixes (price_gte, date_lte, name_like, status_ne), full-text q, _sort/…
Create, update, or delete records in a mock resource. Writes persist (unlike JSONPlaceholder/FakeStoreAPI). POST creates (auto-id), PUT replaces, PATCH merges, DELETE removes. id required for PUT/PATC…
Generate realistic fake data instantly — stateless, nothing is created or stored, no project or adminKey needed. Ready-made resource shapes (FakerAPI-compatible): persons, users, addresses, companies,…
Define a custom endpoint on a project (like /health, /config/:key, or a catch-all /webhooks/* request bin). body is a response template: {{query.x}} {{params.x}} {{body.x}} {{headers.x}} {{method}} {{…
Read the project's request inspector: the most recent requests that hit the mock API (method, path, query, status, origin, captured headers incl. x-* — authorization redacted to its scheme — and a bod…
Mint (or manage) a READ-ONLY share link for a project: a browser URL you can hand to a human reviewer — they can browse the data, endpoints, snapshots and the live request inspector, but can't write a…
Permanently delete a project and ALL its data (records, resources, snapshots, custom routes, webhooks, request log). Irreversible. Good practice for short-lived test projects: clean up when your sessi…
Deterministic test fixtures + eval grading: save the project's entire dataset under a name, restore it exactly later, or DIFF it against live data (list/delete too). action:"diff" is machine-checkable…
One call = the whole eval grade. Composes the state check (snapshot diff vs live data) with trajectory constraints on the request log into a single {pass, checks[]} verdict. Pass snapshot:"expected" t…
Live status of ~58 public mock/testing APIs — JSONPlaceholder, httpbin.org, ReqRes, FakeStoreAPI, DummyJSON, Postman Echo, httpstat.us, Mocky, Mockbin, CrudCrud, restcountries, and more — checked with…
Free downtime alerts for any public URL — no account, armed in one call. action:"create" {url, notify?}: Mockbird GETs the url every 30 minutes from Cloudflare's network (8s timeout, 2xx/3xx = up; a t…
Dead man's switch for cron jobs, scheduled tasks, and recurring agent runs — the INVERSE of uptime_monitor: the JOB pings Mockbird, and if the ping stops arriving the alert fires once (plus one recove…
Subscribe to down/recovered alerts for any of the public mock/testing APIs tracked by check_api_status (httpbin, JSONPlaceholder, ReqRes, FakeStoreAPI, DummyJSON …). action:"subscribe" {service, notif…

Stand up a live hosted mock REST API matching a plain-English description, verify it, and hand back working URLs.
Turn an OpenAPI/Swagger spec, json-server db.json, Postman collection, HAR capture, VCR/vcrpy cassette, CSV, or bare JSON array into a live hosted mock API.
Point error/retry/timeout handling at a mock that actually misbehaves on demand (500s, chaos, latency, rate limits, scripted sequences).
Arm free downtime alerts: an uptime monitor for a public URL (checked every 30 min), or a heartbeat (dead man's switch) for a cron job / recurring task. No account needed.
Check live status of a public mock/testing API (httpbin, JSONPlaceholder, ReqRes, FakeStoreAPI …) and, if it's failing, wire up a hosted drop-in replacement.
