Tools
| Tool | Description | Behaviour |
|---|---|---|
| ask_aifree | A short answer about free AI offers grounded in the verified catalog, citing only offer slugs it was shown. Declines questions outside the catalog. Cached per question for 24 h; subject to a daily budget. | Read-only |
| build_stack | The aifree.dev/stack builder: for a template (chat, rag, image, voice, agent, finetune) one free pick per slot (llm, emb, vec, host, gpu, tts, stt, image) with alternatives, the tightest published LLM requests per day, cards and programs to watch, and a shareable URL. Optionally pin a slot to an offer slug, require no card, or limit to a country. | Read-only |
| check_eligibility | Use when someone asks what free AI they qualify for given who they are, e.g. "I am a student in Vietnam with no credit card, what free AI can I get?". Same rules as the aifree.dev/unlock quiz: student and startup programs only when the profile says so, no-card drops offers that ask for a card, country drops offers recorded as other-countries-only (offers with no recorded region stay in and are counted in unrecordedRegionCount), building narrows by category. All parameters are optional; omitted ones mean not a student, no startup, anywhere, card OK, any category. Unknown values are ignored the same way. Returns verified rows first, then by USD value. totalUsd sums USD headline values of verified rows only (tokens, requests, images or minutes count as $0, no exchange rates); listed rows are public but not yet checked by a person. limit (default 20, max 50) only trims the returned list: total, verifiedCount and totalUsd cover every match. Each provider decides who qualifies; cite the offer url and the unlockUrl (the same result as a page). | Read-only |
| compare_offers | A markdown comparison table (provider, what is free, limits, card rules, catch, expiry, status) for 2-8 offer slugs. | Read-only |
| find_models | Which free API tiers serve an LLM model, with the published free-tier rate limits (RPM, RPD, TPM, TPD, requests/month), context window, tool calling and JSON mode (structured output). Same rows and ranking (most requests per day first) as the free LLM API picker. Search by model or provider name, optionally by family. | Read-only |
| get_model | One model by slug (an alias slug resolves to the canonical one) with every live free source: offer, provider, verified or listed, card rule, context and the published rate limits (rpm, rpd, tpm, tpd, rpmo; null = not published). Same record as GET /api/v1/models/{model}. | Read-only |
| get_offer | Full details for one offer by slug (the last path segment of an aifree.dev/offer/... URL), including the write-up and, for API free tiers, the models served with their published rate limits (rateLimit: rpm, rpd, tpm, optional tpd and rpmo; null = not published), the API id of each model when recorded (apiId), whether its vendor documents JSON mode / structured output (structuredOutput, omitted when unknown), and the API base URL with its request shape (apiBaseUrl, apiCompat: openai, anthropic, google or custom). | Read-only |
| get_status | aifree.dev own status: overall verdict, 30-day uptime, per-path checks and background job health. Same report as GET /api/v1/status. | Read-only |
| list_free_llm_apis | Free LLM / inference API tiers and credits (Gemini, Groq, OpenRouter, Mistral, Cohere, NVIDIA, …) with their limits and card rules. | Read-only |
| list_models | Every model some live free offer serves (the data behind aifree.dev/model and GET /api/v1/models), most free sources first: slug, family, vendor, context window, tool calling, vision, JSON mode, open weights and how many free sources serve it. Filter by name, family, provider, capability or minimum context; then call get_model for the sources and rate limits. | Read-only |
| list_providers | Every provider with public offers: slug, offer count, categories, free types and its offers with status and URL. Same data as GET /api/v1/providers. | Read-only |
| offer_history | What changed on one offer, newest first: its changelog events (listed, verified, terms_updated, expired, incidents, …) and edits to its public facts (what is free, limits, card rule, expiry, vendor URL), each with a { from, to } diff when fields changed. Same data and paging as GET /api/v1/offers/{slug}/history. | Read-only |
| recent_changes | What was listed, verified, changed or expired recently, newest first. | Read-only |
| search_free_ai_offers | Find free AI tools, API free tiers, credits and programs. Free text plus optional filters; returns the best matches with limits, card rules and the page URL to cite. | Read-only |
