Best AI APIs & Infrastructure
Tools are ranked by user rating. The ones we have reviewed also carry our own score out of 10.
APILayer is a catalog of data APIs behind one account and one key, covering geolocation, finance, flights, search and more. The pages we read describe a free start with no card, clear upgrade rules and a published uptime figure. Specific plan prices and quota sizes were not on those pages, so check them per API.
Flaq.ai is a pay-as-you-go API hub that puts many image, video, 3D, music and language models behind one interface. Prepaid credits never expire and there is no subscription, which suits uneven workloads. Refunds are at the company's discretion, and data passes through several third-party AI platforms.
Bright Data is a broad web data platform built around proxies, scraping APIs and datasets, with a published free tier and usage-based pricing. It suits technical teams that need to collect public web data at scale, but its range of products takes some time to sort through.
Context.dev is a developer-focused web data API for AI agents, covering scraping, search, crawling and company data under one credit balance. Pricing is transparent and starts free. The notable caveat is that request content may be used to improve its models unless zero data retention is used.
APITemplate.io is a developer-oriented service for generating PDFs and images from templates, with a visual editor, no-code connectors and a free plan. It publishes clear plan tiers, a SOC 2 Type II claim and a Singapore company address. It is narrow by design, so it fits document and image automation, not general AI work.
Kie AI is a pay-as-you-go gateway that puts video, image, music and chat models behind one API and one credit balance. It publishes per-model prices next to official ones, but the savings claims are the company's own and the pages say little about model terms.
AIMLAPI is a model aggregator that puts hundreds of AI models behind one key and one balance, with no markup over provider prices. It suits developers who want to switch models easily, but the strict no-refund policy means you should top up in small amounts.
