auto pick for you. A provider serves only the methods marked for it; ask a method for another’s provider and it says so, naming the ones it does serve.
Your queries go to the provider you select, and each provider’s terms govern your use of its
results. WebRouter does not change them. Provider names and logos are trademarks of their owners,
used here for identification only.
Which provider serves which method
✓ the provider serves this method, with its key (Configuration names each variable). keyless means it also works with no key, rate-limited.
auto is the default for every method and picks among the providers you can use.
Working with no credentials
You can start with no API keys.auto, the default for every method, uses the providers you have a key for first, and falls back to free tiers when you have none.
- Rate limits. Free tiers are rate-limited. When one is throttled, the next in the list answers.
- Which one answered.
response.providernames the provider that served the call, never"auto". - Missing key. A method with no free tier raises an error that names the key to set.
