DeepSeek Opens App Tools as Low-Cost APIs, Adding Search, File Reading and Voice

·1 views

On 13 November 2026, DeepSeek made the tools built into its consumer app available to developers as APIs. Chat requests to its deepseek-flash model can now use web search, multi-step search, file input, URL reading and content safety checks, with the tools run server-side. Standalone APIs for search and fetch, OCR, speech-to-text and text-to-speech are also offered on a pay-as-you-go basis with no monthly fee. The company's vendor-reported prices are low, and an off-peak discount halves token costs for flash-model workloads. The speech services are the most notable addition, since DeepSeek previously had no public voice endpoint, though the article's authors had not yet tested voice quality.

How Lua obfuscation works and what it can and cannot protect

Developers shipping Lua scripts, such as Roblox games or embedded logic, risk exposing source code, game formulas, remote event patterns, and accidentally embedded secrets. The article outlines common obfuscation techniques, including minification, string encryption, control-flow flattening, and bytecode-level transforms, each trading off protection against runtime performance. It stresses that no client-side obfuscation is a guarantee, since determined reverse engineers can eventually recover logic, but it raises the cost of theft from minutes to hours. The author recommends keeping real secrets and trust-critical validation on the server, testing obfuscated output on the executors users actually run, and keeping unobfuscated source under version control. The piece is framed as defense-in-depth against casual copy-paste theft rather than a complete safeguard.

Setting up Supabase email sign-in and a secure profiles table for iOS apps

A developer walks through a standard iOS backend setup using Supabase, covering email sign-in, per-user data storage, and access control. The recommended approach stores profile data in a public.profiles table linked to the auth user ID, with cascading deletion so no orphaned rows remain. Row Level Security policies restrict each signed-in user to reading and updating only their own row, since the public app key itself provides no protection. Column-level grants further limit client edits to specific fields, keeping sensitive attributes such as billing status writable only by the backend. A database trigger creates the profile atomically at sign-up, avoiding gaps caused by network failures or interrupted app sessions.

Fan build planner encodes entire game builds in URL fragments with patch-version stamps

A developer of a fan-made planner for the browser survivor game Azeroth Survivors describes storing builds with no accounts or database, placing everything in the URL fragment so that saving and sharing are the same action. Builds are packed into a fixed byte layout covering class, skill slots, banished skills, and talent ranks in 3-bit fields, producing a 32-character base64url string for a 40-talent class. Skills are referenced by index rather than name, so the format carries a version nibble that must be bumped whenever offsets or widths change, and decoding returns null on mismatch. A later format adds a name, a game version stamp, and per-stage plans, letting the planner check whether a shared link's talents, skills, and upgrades still exist after a game patch.

Comparing subscription offers with a transparent, auditable cost function

A low monthly price can conceal an upfront fee or a longer contract, so comparison tools should expose their assumptions before ranking offers. The article recommends keeping upfront cost, monthly charge, term length, and unconditional credits as separate inputs, and withholding any conditional rebate until its conditions are satisfied. It includes a sample JavaScript function that validates inputs and computes total cost as upfront plus monthly multiplied by months, minus credits. Using illustrative figures, one offer with no upfront fee and $85 monthly over 24 months totals $2,040, while another with $600 upfront and $40 monthly totals $1,560, a $480 difference before taxes or fees. The author stresses showing the formula and time horizon with results, storing currency as integer minor units, and treating estimates as non-binding rather than guaranteed final bills.
