client.o_auth should be client.oauth — OAuth and SCIM initialisms missed by #561

[rajarshidattapy]

Summary

PR #561 ("chore(gen): render BYOK/TTS/STT as initialisms in generated symbols", merged
2026-07-30) normalized three initialisms via customCasings in .speakeasy/gen.yaml. Two
more were left behind, and they fail in two different ways:

• client.o_auth — the attribute should be client.oauth
• Scim — the class should be SCIM

The first is user-facing and the reason for this issue; the second is the same defect #561
was fixing, just missed.

Current behavior

>>> client = OpenRouter(api_key="...")
>>> hasattr(client, "oauth")
False
>>> hasattr(client, "o_auth")
True

From src/openrouter/sdk.py:

57:    tts: "TTS"
59:    stt: "STT"
61:    o_auth: "OAuth"      # class right, attribute wrong
65:    byok: "BYOK"
86:    api_keys: "APIKeys"
102:    scim: "Scim"        # attribute right, class wrong

Why these two are different

#561 added:

customCasings:
  byok:
    initialism: true
  stt:
    initialism: true
  tts:
    initialism: true

Before that commit the attributes were already byok / stt / tts; what was wrong were the
class names, Byok / Stt / Tts. The initialism: true entries fixed the classes.

• SCIM has exactly that problem and no entry: the class is still Scim while BYOK,
  STT, TTS, and APIKeys are all correct. Adding scim: {initialism: true} should be a
  direct copy of the chore(gen): render BYOK/TTS/STT as initialisms in generated symbols #561 recipe.
• OAuth is the inverse. Its class name is already correct (class OAuth(BaseSDK)), but the
  tag OAuth is mixed-case, so the snake_case attribute splits on the internal capital and
  becomes o_auth. A plain initialism: true here would presumably target OAUTH and make
  the class name worse. The desired output is the mixed pair — attribute oauth, class
  OAuth — so this needs whichever knob produces that, and whoever runs the generator will
  know better than I do which one.

Docs already disagree with the code

The generated docs directory is docs/sdks/oauth/, titled "OAuth", but every snippet inside
it calls the split attribute:

res = open_router.o_auth.exchange_auth_code_for_api_key(...)
res = open_router.o_auth.create_auth_code(...)

docs/sdks/scim/README.mdx by contrast uses open_router.scim.…, matching its directory.

Compatibility note

Renaming client.o_auth to client.oauth is a breaking change for anyone already calling it,
and the SDK has been stable since v1.0. Worth considering keeping o_auth as a deprecated
alias for a release or two — the same treatment beta.responses got in 1477485 — rather
than a hard rename. The Scim → SCIM change carries the same caveat if anyone imports the
class directly, though the scim attribute is unaffected.
