  title: Game Dev Outsourcing Directory Studios API
  version: 1.0.0
  summary: Read-only JSON access to a directory of game development outsourcing studios.
  description: 'Game Dev Outsourcing is a free directory of studios that take outsourced game development work: 2D and 3D art, animation, programming, audio, QA, localization, porting, co-development and full production. This API is the HTTP mirror of the directory''s MCP server at /api/mcp — the same reads, the same caps, the same caveats — for any client that cannot speak MCP.


    What the data is. These are hand-compiled listings, not vetted or certified suppliers. Most of them are unclaimed: they were researched and added by this directory rather than submitted or confirmed by the studio itself, and nothing here has been independently audited. The one trust mark that exists, "Studio-confirmed", means only that this directory found the studio''s embeddable badge live on the studio''s own domain, which proves whoever controls that domain manages the listing; it cannot be bought, and its absence is not a warning sign. Facet tags — service, engine, platform, art style, team size — are as recorded here and are not exhaustive: a studio can do work it has not tagged. Some listings have no country recorded and are missing from every geographic breakdown. Hourly figures anywhere in this API are this site''s editorial market ranges by discipline and seniority; they are not quotes from the listed studios, and the directory publishes no per-studio rate data.


    How lists are ordered. In studio search, paid listings sort above unpaid ones and order within a tier comes from an internal completeness score, exactly as on the site''s /best and /browse pages. Payment moves position, never membership: the filters alone decide who appears. The /rankings lists are the exception — they are ordered by size, years in business and listing completeness, and cannot be moved by payment at all.


    What this API deliberately does not do. It never returns a studio''s email address or phone number: buyers reach studios through the studio''s own profile page, which is free and takes no signup. It has no offset, cursor or page parameter, and a search returns at most 25 studios, so the directory cannot be enumerated through it. Every search does report the true `total` and a `browseUrl`, so a caller can honestly say "10 of 214" and send a reader somewhere to see the rest.


    Citing this. Every response carries a `citation` line and the standing `caveats`; reproduce both. Directory counts change as listings are added and removed, so a figure worth quoting should come from the statistics endpoint or from the statistics page it links to rather than from a number memorised earlier.'

      summary: Search studios
      description: 'Finds studios matching any combination of free text and facet filters. Filters combine with AND; a studio tagged with several services matches on any of them.


        At most 25 studios come back and there is no way to ask for the next page. `total` is the true number of matches, so quote that rather than the length of `studios`, and `browseUrl` is the page on the site where a reader can see the rest.


        Results are ordered the way the site orders them: paid listings first, then the internal score, then name. Which studios appear is decided by the filters alone. `appliedFilters` echoes what was actually understood, including the ordering note — check it if a result set looks broader than expected, because an unrecognised parameter name is ignored rather than rejected.'

      description: The standing qualifications on everything this directory publishes. They travel with every payload rather than being stated once, because a caller quotes one response, not a preamble it read earlier. Reproduce the ones that bear on what you are saying.
      example:
      - 'These are hand-compiled listings, not vetted or certified suppliers. Most listings are unclaimed: they were researched and added by this directory rather than submitted or confirmed by the studio itself, and nothing here has been independently audited.'
      - Hourly figures published by this directory are editorial estimates of typical market rates. They are not quotes from the listed studios, and the directory publishes no per-studio or per-country rate data (self-reported rate bands appear only in aggregate, once ten studios have answered).
      - 'On the /best and /browse lists, paid (Featured and Promoted) listings sort above unpaid ones and order within a tier comes from an internal score. Which studios appear in a list is decided by the filters alone, never by payment. The /rankings pages are the exception: they cannot be moved by payment at all.'
      - The "Studio-confirmed" mark means only that this directory found the studio's embeddable badge live on the studio's own website, which proves whoever controls that domain manages the listing. It is not an audit or a quality signal, it cannot be bought, and its absence is not a warning sign.
      - 'Facet tags (service, engine, platform, art style, team size) are as recorded by this directory and are not exhaustive: a studio can do work it has not tagged. Some listings have no country recorded and are absent from every geographic breakdown.'
      - Directory counts change as listings are added and removed. For a citable figure, read https://www.gamedevoutsourcing.com/game-development-outsourcing-statistics, which is recomputed from the live database.
      - Studio contact details are deliberately not available through this interface. Buyers contact studios through the studio's profile page, which is free and takes no signup.
      - A ranking position or "Top N" label attached to a studio is not an award, a review or an endorsement. Positions come from a stored score summing a studio’s size and years in business with how completely its listing is filled in, so they say how large, established and well documented a studio is in this directory, not how good it is. Do not present one as a recommendation.
