Find keywords worth ranking for and see who currently owns the SERP.
Separate vendor accounts and API keys for each data source, different auth schemes and response formats, per-seat subscriptions your agent uses a fraction of, and glue code that breaks whenever one vendor changes.
One key and one wallet. Call seo.keywords, seo.serp, seo.backlinks as canonical capabilities with stable schemas; the router picks the provider on evidence and every run shows provider, latency, quote and charge.
| Capability | Description | Providers |
|---|---|---|
| seo.keywords | Search volume and keyword ideas for a seed keyword. | |
| seo.serp | Live search engine results for a keyword and location. | |
| seo.backlinks | Backlinks and referring domains for a target domain. | |

Pricing: the maximum cost is quoted and reserved before the call; failed or unmatched calls are released, with any disclosed exceptions shown by /v1/inspect. Reliability: measured provider success rates will be published once minimum sample sizes are reached; examples on this page are labeled and simulated until then. Limitations: capabilities marked coming soon are not yet executable.
