How this service works
Auditá hasta 10 referencias por lote en DOI, BibTeX, RIS o CSL-JSON. Compará campos con Crossref y DataCite, recuperá evidencia y exportá metadatos registrados. Muestras gratuitas y suscripción prepaga.
Output
A JSON object containing the subscription plan name (e.g. 'research-30'), a boolean indicating whether auto-renewal is enabled, the duration of the plan in days, and the number of citation-audit queries included in the plan.
Example use cases
Pre-audit quota check
“Before I run a big batch of 50 DOI references through CitationCheck, can you look up my current subscription to see how many queries I have included and whether I have enough headroom?”
Subscription renewal decision
“I'm not sure if my CitationCheck HG plan auto-renews — can you pull up my subscription details so I know whether I need to manually renew before my 30-day period ends?”
Research workflow planning
“I need to plan out my citation auditing work for this month — can you fetch my CitationCheck HG subscription info so I know how many reference-batch queries are available and what plan I'm on?”
Technical details
Endpoint
GEThttps://microinvestigacion-hg.heroga32881.chatgpt.site/api/subscription?utm_source=zero.xyzWhen to prefer
Use this endpoint when an agent needs to check the remaining quota or plan details before invoking a citation audit batch, or when deciding whether a subscription renewal is needed. Prefer this over the audit endpoints when the goal is account/plan introspection rather than actually auditing references.
Side effects
- 401/402 Unauthorized – missing or invalid payment/auth credentials
- No active subscription found – account has no current plan
- Network timeout reaching chatgpt.site subdomain
- Empty or malformed JSON response if subscription data is unavailable
