Overview

This operation is part of the SEO API in the seo category. It uses the same Bearer token, request tracing, error model, and billing envelope as every UnifAPI endpoint, so agents can switch between platforms without custom per-vendor glue code.

Use it when a workflow needs SEO public data but should still keep one API key, one account balance, and one predictable JSON contract across social, live public-data sources.

Common agent workflows

  • Fetch canonical public SEO content for summarization, ranking, monitoring, or enrichment.
  • Attach engagement, author, media, and source metadata to an agent workflow.
  • Give an AI agent a stable SEO data source without building a per-platform integration.
  • Normalize SEO responses into the same UnifAPI envelope used across the catalog.
Response shape

Unified envelope, platform-native fields

  • Lookup responses return one canonical object in `data` with stable identifiers, source URLs where available, and platform-specific metadata normalized into predictable JSON.
  • The operation has a 50 credits ($0.05) minimum charge, so `billing.records_charged` can be higher than the visible records returned.
  • A not-found or invalid-input condition uses the unified UnifAPI error shape, so callers do not need special handling for each source platform.

Billing

This operation charges 1 credit per billable record, with a 50 credits ($0.05) operation minimum. Public responses include billing metadata with credits charged, records charged, and remaining workspace balance. Incorrect Credit deductions caused by platform failures can be restored as billing corrections.

Errors and retries

Authentication, validation, rate-limit, not-found, and provider errors use the unified UnifAPI error format. Agents should log `request_id`, retry only retryable failures, and treat invalid API keys, disabled keys, and expired keys as the same public `unauthorized` error type.
