## CometAPI

CometAPI is an aggregation layer for large language and multimodal model providers. Instead of maintaining separate accounts, keys and billing relationships with OpenAI, Anthropic, Google and a growing set of image, audio and video vendors, teams sign up once, get a single API key, and call any of 500+ models through an OpenAI-compatible base URL. Existing SDK code usually works after changing the base URL and model name, which keeps migration effort low.

The commercial pitch is straightforward: pay-as-you-go credits, line-item pricing for every model, and rates set below official vendor pricing, with the platform advertising ongoing savings of roughly 20 to 40 percent. There is no monthly subscription or minimum spend, unused credits carry forward, and the model catalog is searchable with side-by-side pricing and capability comparisons. Because model names are the only thing that changes when you switch vendors, teams gain portability if a provider raises prices or has an outage.

Operationally, CometAPI positions itself as production infrastructure rather than a demo playground. It advertises 99.9% service availability and average latency under 400 ms, exposes an API status page and benchmarks, and offers a dashboard for spend, latency and call volume with budget alerts. Enterprise-oriented features include centralized accounts for multiple teams, per-team budgets, encrypted transit and a stated policy that customer data is not used to train models. Integrations with coding agents, low-code automation platforms and app builders let teams plug the gateway into existing workflows rather than rebuilding them.

**Pricing & Plans:** Pay-as-you-go API credits with no monthly subscription, minimum spend or credit card required at signup. CometAPI advertises per-model rates below official vendor pricing, typically 20-40% cheaper, and test credits are included when you create an account.

- **One key for 500+ models:** Replace separate OpenAI, Anthropic and Google credentials with a single key and switch models by changing one line of code.
- **OpenAI-compatible endpoint:** Route text, reasoning, coding, image, audio and video workloads through one OpenAI-compatible base URL without rewriting your app.
- **Transparent pricing and savings:** Line-item pricing per model with discounts below official vendor rates, pay-as-you-go with no monthly subscription or minimum spend.
- **Usage analytics and cost control:** A real-time dashboard tracks spend, latency and call volume so you can set budget alerts and compare models side by side.
- **Prebuilt tool integrations:** Works with Claude Code, Codex, Cline, Dify, n8n, Zapier, Coze and other agent, automation and app-building tools.

**Strengths:** One credential and one endpoint for 500+ models from many providers; OpenAI-compatible format means existing code keeps working with minimal changes; Pay-as-you-go credits with no monthly fee and unused balance carried forward; Dashboard for spend, latency and call volume with budget alerts

**Limitations:** You depend on a third-party intermediary for uptime and latency on every routed model; Some catalog entries are marked coming soon, so not every listed model is instantly available; Pricing and availability can shift as upstream vendors change their own rates

## Seedance 2.5 API

Seedance 2.5 API positions itself as a practical working site for engineers and product teams building video generation features. Rather than a simple landing page, it mixes a prompt-and-example gallery, step-by-step workflow guidance, an API quickstart with Python and JavaScript snippets, and a detailed pricing reference arranged by resolution and clip length. The latest generation, Seedance 2.5, is documented as a pending release — the site openly states that pricing and model access are not yet open and advises teams not to hard-code a model ID in production until routing is confirmed.

The currently usable baseline is Seedance 2.0, which the site routes through EvoLink and prices per generated video (for example $0.46 for a 480p 5-second clip up to $15.18 for a 4K 15-second clip). The workflow is deliberately simple: register and top up, send a RESTful generation request, then poll a task ID or receive a webhook when the video is ready. Commercial usage rights are included and no subscription is required.

The comparison tables contrast Seedance 2.5 against Seedance 2.0, Kling 3.0 and Veo 3.1 on resolution, duration, audio support and input modalities, giving teams a starting point for cost modelling before they commit engineering time. Because the site aggregates speculation and announced information about an unreleased model, its forward-looking specs should be treated as reference only, not a guarantee.

**Pricing & Plans:** Pay-as-you-go with no subscription required; Seedance 2.0 is billed per generated video (e.g. $0.46 for 480p/5s up to $15.18 for 4K/15s), while Seedance 2.5 pricing is listed as coming soon. Enterprise SLA and volume pricing are available on request.

- **RESTful video generation API:** Three-step flow — POST a prompt, poll the returned task ID, then download the finished video URL — with ready-to-copy Python and JavaScript snippets for text-to-video, image-to-video and reference-to-video.
- **Transparent cost reference:** Per-video and per-second pricing broken down by resolution and duration for Seedance 2.0, alongside public reference prices for Kling 3.0 and Veo 3.1 so teams can budget before building.
- **Seedance 2.5 vs 2.0 comparison:** A capability-by-capability breakdown covering resolution, clip length, reference assets, local editing, multilingual speech and physics simulation, with clear flags on what is announced versus confirmed.
- **Prompt and example gallery:** Real outputs generated through the API with the prompts that produced them, covering documentary, martial-arts restyle, VFX edit and fashion-film briefs.
- **Production onboarding guidance:** Documentation on API access status, model IDs, webhook callbacks and the evaluation criteria teams should test before making a new model their default route.

**Strengths:** Clear, per-video pricing math for Seedance 2.0 that makes production budgeting straightforward; Honest status reporting — the site explicitly labels Seedance 2.5 specs as announced/pending rather than confirmed; Ready-to-run Python and JavaScript API snippets lower integration time; Comparison tables put Seedance, Kling and Veo cost and capability side by side in one place

**Limitations:** Seedance 2.5 pricing and model access are not yet available, so the headline promise is still forward-looking; It is an independent third-party hub, not an official ByteDance product page, so specs should be verified against primary sources; Some competitor pricing on the comparison page is public reference data that can drift out of date
