Is this your server? Own a server? ToolFit hosted watch re-checks it every 24 h ($0.25 per 30 days) or 6 h ($0.60) and sends you an HMAC-signed webhook when its tools or grade change: POST https://api.youraitools.co/toolfit/v1/watch. To opt out, see About & opt-out.

create_project | 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. Presets seed a full backend: blog (posts/comments/authors), ecommerce (products/orders/customers/reviews), saas (users/teams/events), payments (Stripe-shaped sandbox: charges/refunds/subscriptions/c params: name, preset, ttl |
import_data | 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 POST /invoices/{id}/send) become custom routes serving the spec's own examples verbatim; json-server db.json → hosts your exact records; Postman Collection v2.x → resources from requests, saved example params: content*, name, resource, seed, ttl |
fork_project | 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, fork_project per run with a ttl (crashed runs can't leak sandboxes — the fork deletes itself), let the agent mutate the fork freely, then grade with snapshots action:"diff". withSnapshots:true also c params: project*, adminKey, name, withSnapshots, ttl |
add_resource | 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, events) or fields: an array of {name, type} where type ∈ uuid|firstName|lastName|fullName|username|email|avatar|image|word|words|title|sentence|paragraph|number|price|percent|boolean|date|pastDate|future params: project, adminKey, name*, template, fields, seed |
project_info | 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. Try project "demo" for the shared public playground. params: project* |
query_records | 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/_order (or _page/_limit for pagination), select (field projection, e.g. "name,price"), _expand=<parent>/_embed=<children> relations. Failure simulation for testing: mock_status=503 forces that status, params: project*, resource*, id, params |
write_record | 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/PATCH/DELETE. params: project*, resource*, method*, id, body |
generate_fake_data | 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, books, products, texts, images, places, credit_cards (credit cards are Luhn-valid; book EAN13/ISBN13 checksums are real; image URLs are live SVG placeholders served by Mockbird). Or pass fields for a params: resource, quantity, seed, fields, params |
custom_route | 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}} {{path}} {{now}} {{ts}} {{uuid}} {{rand}}; triple braces {{{body}}} insert raw JSON. Custom routes take precedence over resource routes; '*' catch-alls are a fallback. Max 20 routes/project. params: project*, adminKey*, method, path*, status, body, contentType, delayMs |
inspect_requests | 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 body snippet for writes). Use it to VERIFY what your app / tests / webhook sender actually sent: point code at the mock, run it, then inspect. Pairs with custom_route catch-all bins (e.g. /webhooks/*) fo params: project*, adminKey, limit, method, path, status, status_gte, status_lte, since |
share_project | 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 and never see the adminKey. Agent workflow: build or mutate a sandbox, then share_project and give your human the shareUrl to review your work — no key handover. Works even when the project is in prote params: project*, adminKey*, action |
delete_project | 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 session is done. Requires the adminKey. params: project*, adminKey* |
snapshots | 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 grading — compares the named snapshot (expected) against live data (actual, or another snapshot via against) and returns {identical, summary, resources[] with per-record added/removed/changed field d params: project*, adminKey*, action*, name, against, ignore, data |
verdict | 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" to require live data to match that snapshot (author it as the answer key first via snapshots action:"save" with data), and/or trajectory constraints like [{method:"DELETE", count:0}, {method:"POST", pa params: project*, adminKey*, name, snapshot, ignore, trajectory |
check_api_status | 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 a plain keyless GET every 30 minutes from Cloudflare's network (a service answering HTTP 200 error envelopes is probed by body and honestly reported as failing). No arguments → compact summary: up/do params: service |
uptime_monitor | 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 timeout/TLS/DNS blip on an otherwise-up url is confirmed with a same-run retry before it counts); with notify, that webhook gets ONE message when it goes down and ONE when it recovers — debounced (two params: action*, url, notify, id, secret |
heartbeat | 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 recovery message when pings resume). action:"create" {name?, period_minutes, grace_minutes?, notify?}: period_minutes = how often the job runs (30–10080); grace defaults to half the period. With notify, mis params: action*, name, period_minutes, grace_minutes, notify, ping_url, id, secret |
watch_service_status | 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, notify?}: service is an id from check_api_status (or "*" for all tracked services). With notify, that webhook gets one message when the service goes down and one when it recovers (debounced across two cons params: action*, service, notify, id, secret |
image_url | Mint a permanent, keyless image URL rendered by Mockbird — README badges (including LIVE record-count badges), chart images, QR codes, Open Graph cards, placeholder images, initials avatars. Deterministic: the same URL renders the same image forever (no account, no expiry, no watermark). Params are validated against the real endpoint before the URL is returned, so a returned URL is guaranteed to r params: kind*, params, size, format, project |
