SpeedyIndex API-compatible indexers

What compatibility means

SpeedyIndex publishes a v2 REST API (documentation) that many SEO scripts, spreadsheets and internal tools call directly. Normally, moving to another indexer means rewriting that client: new paths, new payloads, new status codes.

IndexChex took a different route for its API v2. It reproduces SpeedyIndex's endpoint paths, request bodies and response format, so an existing integration keeps working when its base URL and API key are changed to IndexChex's. The implementation details are recorded on the API v2 compatibility evidence page. None of the other nine tools on the comparison table stated SpeedyIndex compatibility on the pages checked on 2026-10-08.

Endpoints mirrored

All requests authenticate with the API key as the raw value of the Authorization header. {engine} is the search engine segment, and IndexChex accepts only google; {type} is indexer (submit links for indexing) or checker (check indexation). The IndexChex base URL is https://indexchex.com/api.

Responses carry a numeric code: 0 for success, 1 when the balance needs a top-up, 2 when the server is busy and the request should be retried. Task objects include id, size, processed_count, indexed_count, title, type, is_completed and created_at.

A minimal switch

A create request in SpeedyIndex format looks like this:

curl -X POST \
  -H 'Authorization: <API KEY>' \
  -H 'Content-Type: application/json' \
  -d '{"title":"guest posts","urls":["https://example.com/post"]}' \
  https://indexchex.com/api/v2/task/google/indexer/create

To move the call, swap the SpeedyIndex host for https://indexchex.com/api and the key for an IndexChex API key from the account's API settings. The body and the response handling stay the same. Teams running both services side by side can keep one client and select the provider in configuration.

What does not carry over

Compatibility covers the calls, not the commercial terms:

• Billing basis. SpeedyIndex charges 100 tokens per indexed link and refunds unindexed links after 7 days (source). IndexChex charges 1 credit per submitted URL in standard mode and does not refund URLs Google declines to index.
• Balances. Each provider has its own account and balance; nothing transfers.
• Report meaning. A SpeedyIndex report reflects SpeedyIndex's checking; an IndexChex report reflects IndexChex's four-query index check. Counts for the same URLs may differ between providers.
• Features outside the schema. IndexChex options such as instant mode or scheduled re-checks are not part of SpeedyIndex's schema; the native IndexChex endpoints are documented on the API v1 page.

Why this matters for alternatives

The switching cost of an indexer is usually the integration, not the account. A compatible API lowers it to a configuration change, which makes A/B testing two vendors on the same URL lists practical.
