Provider '{name}' not found in the registry.Available provid

Error message

Provider '{name}' not found in the registry.Available providers: {list(self.registry.providers.keys())}

What it means

OpenBBError from QueryExecutor.get_provider: it lowercases the requested provider name and looks it up in the provider registry (built from installed openbb-<provider> packages). If the name is absent - misspelled, or the package simply not installed in this environment - it raises this error listing every registered provider name.

Solutions

Pick a provider from the list in the error message (or obb.coverage.providers)
Install the desired provider: pip install openbb-polygon
Fix typos/case in the provider argument or in openbb_settings.json defaults
Verify you are in the same virtualenv/conda env where the provider was installed

Example fix

# before
res = obb.equity.price.historical('AAPL', provider='polygon')  # not installed

# after
pip install openbb-polygon
res = obb.equity.price.historical('AAPL', provider='polygon')

Defensive patterns

Strategy: validation

Validate before calling

from openbb import obb

def provider_available(name: str) -> bool:
    return name.lower() in set(obb.coverage.providers)

Type guard

def is_registered_provider(obb, name: str) -> bool:
    return isinstance(name, str) and name.lower() in set(obb.coverage.providers)

Try / catch

from openbb_core.app.model.abstract.error import OpenBBError

try:
    res = obb.equity.price.historical('AAPL', provider=p)
except OpenBBError as e:
    if 'not found in the registry' in str(e):
        p = next(iter(set(obb.coverage.providers) & {'fmp', 'yfinance'}))
        res = obb.equity.price.historical('AAPL', provider=p)
    else:
        raise

Prevention

Validate provider names against obb.coverage.providers before requests
Install provider packages in the same env that runs the app
Lowercase provider names in configuration to avoid case surprises

When it happens

Trigger: Calling a command with provider='FMP' works (lowercased), but provider='fmpp' or provider='polygon' when openbb-polygon is not installed raises this. Also occurs when a provider package was uninstalled but remains in user defaults, or when running in an environment where only the core is installed.

Common situations: Typos in provider names; assuming a provider ships with openbb core (only some do); virtualenv mismatch where the provider was installed in a different environment; defaults referencing a provider removed after an uninstall; case variants like 'BenZinga' are fine but 'benzinga-pro' is not.
