# MuscleWiki API Pricing

Plain-markdown mirror of https://api.musclewiki.com/pricing, which is the canonical page.

MuscleWiki API pricing starts free — 500 Playground calls a month — and runs from $10 to $199.99 per month, for 1,000 to 300,000 API calls per month. Most requests cost one API call — the expanded /full endpoints cost more and report their exact cost in a response header — and every paid plan includes commercial use rights.

## Compare every plan

Effective cost is the monthly price divided by the included call quota, rounded
to the nearest cent. It is the number to compare plans on — not the headline
price. "Playground only" means the plan can reach that data only through the
hosted Playground on this site: you still create an API key and the Playground
sends it for you, but that key is refused when you call the API directly from
your own code.

| Plan | BASIC | TESTING | GROWTH | PROFESSIONAL | ENTERPRISE |
| --- | --- | --- | --- | --- | --- |
| Price | Free | $10 per month | $39.99 per month | $99.99 per month | $199.99 per month |
| Included API calls per month | 500 | 1,000 | 30,000 | 100,000 | 300,000 |
| Effective cost per 1,000 calls | — | $10.00 | $1.33 | $1.00 | $0.67 |
| Direct API key access | No | Yes | Yes | Yes | Yes |
| Exercises, search, filters & videos | Playground only | Yes | Yes | Yes | Yes |
| Routines & workouts endpoints | Playground only | No | No | Yes | Yes |
| Bodymap images | Playground only | No | No | Yes | Yes |
| All 14 languages | Playground only | No | Yes | Yes | Yes |

The CUSTOM plan is negotiated and provisioned by our team, so it has no published price and no fixed capability row: call limits and per-feature access are set per agreement. Talk to sales: https://api.musclewiki.com/contact/sales?ref=md.

## Which plan is right for you

Plans differ on two axes: how many API calls you get each month, and how much of
the dataset your API key can reach.

### BASIC — Free

Free evaluation plan for developers who want to try the API in the browser Playground before writing any code — no card required. A Basic key works only through the Playground on this site, never from your own application.

### TESTING — $10 per month

The cheapest way to build against a real API key: enough calls to wire up an integration and run a test suite against English exercise data.

### GROWTH — $39.99 per month

For a shipped app in production that needs exercise data in all 14 languages, with a monthly quota sized for small and mid-sized fitness products.

### PROFESSIONAL — $99.99 per month

For production apps that need the complete dataset — routines, workouts and bodymap images on top of exercises — with headroom for steady day-to-day traffic.

### ENTERPRISE — $199.99 per month

For high-traffic products that need the complete dataset at scale, with the largest self-serve monthly quota and priority support.

### CUSTOM

For teams whose requirements fall outside the catalogue — negotiated call limits, per-feature access and dedicated support, provisioned by our team.

## What happens when you hit your monthly limit

Your quota is a ceiling, not a meter. There is no overage billing: once you have
used every call on your plan, further requests are refused until the quota
resets, and you are never charged for calls beyond your plan.

- **Over-quota requests return HTTP 429.** The JSON body carries `detail`,
  `message` and an `upgrade_url`, plus a `reset_at` timestamp when the reset
  time is known. A matching `Retry-After` header gives the seconds until reset,
  so a client can back off correctly instead of hammering the API.
- **You get warned before it happens.** Usage-alert emails go out at 80%, 90%
  and 100% of your monthly quota, and your dashboard shows live usage against
  the limit. Custom plans get 80% and 100% only.
- **Monthly plans reset on your billing anniversary; annual plans reset on the
  1st.** A monthly subscription's quota resets at the start of each billing
  period rather than on the first of the month. An annual subscription is
  billed once a year but still has a monthly quota, so that quota resets on the
  first of each calendar month — as does the free plan, which has no
  subscription at all.
- **Endpoints outside your plan return 403, not 429.** Asking for a plan-gated
  endpoint — routines, workouts or a non-English language — is a permissions
  answer, not a quota answer, and comes back immediately with an
  `upgrade_url`. Bodymap images behave differently: on a plan that does not
  include them the `bodymap_male` / `bodymap_female` fields simply come back
  `null` instead of a URL, and the bodymap image endpoints themselves answer
  `403` with a plain `detail` message. Expanded endpoints such as
  `/routines/{id}/full` cost more than one call, and those responses — only
  those, since the header is set only when the cost exceeds one — carry an
  `X-API-Calls-Cost` header giving the exact figure.

## Upgrading, downgrading and cancelling

- **Changing plan takes effect as soon as the checkout completes.** You pick the
  new plan from your dashboard and complete a checkout for it. The new quota and
  any newly unlocked endpoints are live on your existing API key straight away —
  your key never changes, so nothing needs redeploying — and your previous
  subscription is then cancelled at the end of the period you have already paid
  for, so it never renews again.
- **Moving between two paid plans works the same way in both directions.** An
  upgrade and a paid-to-paid downgrade both go through that same fresh checkout,
  so a downgrade's smaller quota and narrower endpoint access apply from the
  moment it completes rather than at your next renewal.
- **There is no automatic proration or credit.** Switching plans starts a new
  subscription rather than adjusting the existing one, so the new plan is
  charged in full at checkout and the previous subscription simply runs to the
  end of the period you already paid for. If the timing matters to you, switch
  close to your renewal date — or ask us first.
- **Cancelling keeps your access until the end of the period you already paid
  for.** Cancellation is scheduled rather than immediate: you keep your paid
  plan, its quota and its endpoints until the current billing period ends, you
  are not charged again, and the account then moves to the free plan. Your API
  key keeps working — it is the plan behind it that changes, so calls that need
  a paid feature start returning 403.
- **Monthly plans are month-to-month.** There is no minimum term and no
  cancellation fee on a monthly plan. An annual plan is a twelve-month
  commitment charged upfront — you can cancel it, but those twelve months have
  already been billed. Custom plans are the exception — those terms are
  whatever we agreed with you.
- **Start free, and only pay when you need to call the API from your own code.**
  The free plan needs no card, so you can try the API from the Playground
  (https://api.musclewiki.com/playground?ref=md) with a free key and
  read the documentation before you decide which plan you need.

## Monthly or annual billing

Every paid plan is available on either cadence. Monthly plans renew each month.
Annual plans are charged upfront for twelve months at a 25%
discount and renew yearly until cancelled. The Monthly / Annual toggle on the
plan cards at https://api.musclewiki.com/pricing shows the upfront amount for each plan.

Your monthly call quota is the same either way — 25% off the
price, not 25% more calls. Annual billing changes what you pay
and when, not what your key can do.

Switching between monthly and annual on the same plan is done from your
dashboard; the new cadence starts once the checkout completes. If you need the
two periods to line up exactly, ask us first.
