Introduction
One key, one gateway, credits for work done.
FlashAPI is a hub of first-party APIs. Subscribe once, spend credits, and call the catalog through https://api.flashapi.io with a single X-FlashAPI-Key. It is not a third-party marketplace — every upstream is ours.
X-FlashAPI-Key, not Bearer. Errors are RFC 9457 problem details whose type URIs resolve on this host.Features#
The gateway meters work done, not HTTP status. Here is what ships today:
One API key
flash_ prefix. X-FlashAPI-Key only — no Authorization.
Credits for work
Reserve, X-FlashAPI-Bill, and a hard 402 at zero.
Account rate limits
Global per-account window with Retry-After.
URL majors
Pin v1. No latest. Deprecate, then 410 sunset.
Problem details
Stable code plus a type URI on this site.
YouTube first
getVideoDetails. Public metadata, no stream URLs.
…and more products as the catalog grows.

Mint a key in the dashboard, then call YouTube video details. Read Auth if the header is unfamiliar.
