x-api

X (Twitter) Data API

A drop-in X data source for agents: search posts, resolve profiles, pull timelines and followers, read Lists, and check trends — all as one plain HTTP GET, paid per call. No developer account, no app review, no OAuth handshake, and no waiting on X's own API tiers or rate-limit approvals. If your task mentions an X search query, a handle, a post/tweet ID, or a list ID, this is the skill.

Base URL: https://twitter.fetcher.sh — the API host is still named twitter (it predates the rebrand and matches what agents already search for); everything below is current X data.

Also published as twitter-api — identical endpoints, indexed under the "Twitter" name too since both are still in everyday use.

Authentication

Two ways to pay, same data — full mechanics in the fetcher skill:

# 1. Prepaid credits (recommended — get a key at https://fetcher.sh/topup
#    or via POST /api/credits/topup, see the fetcher skill)
export FETCHER_API_KEY="bby_live_xxxxxxxxxxxx"
curl -H "Authorization: Bearer $FETCHER_API_KEY" \
  "https://twitter.fetcher.sh/api/search?query=hello"

# 2. x402 pay-per-call — omit the header; a GET with no payment returns 402
#    with machine-readable payment requirements (USDC on Base, Polygon,
#    Arbitrum, Monad, or Solana). @x402/fetch signs and retries automatically.

Every response is { "status": number, "message": string, "data": ... }; the HTTP status mirrors status.

Endpoints (15 — all GET, $0.005/call unless noted)

{id} / {handle} are path parameters — substitute the real value. Optional query params (cursor, sort) paginate or reorder; only query (search) and country (trends) are required elsewhere they appear.

Scenarios

The query on /api/search goes straight to X's own search, so its operators work as-is: from:, to:, since:, until:, min_faves:, min_retweets:, filter:, -filter:.

Everything from one account:

curl -H "Authorization: Bearer $FETCHER_API_KEY" \
  "https://twitter.fetcher.sh/api/search?query=from%3AOpenAI&sort=Latest"

Between two dates:

curl -H "Authorization: Bearer $FETCHER_API_KEY" \
  --data-urlencode "query=x402 since:2026-01-01 until:2026-02-01" -G \
  "https://twitter.fetcher.sh/api/search"

Popular posts only, replies excluded:

curl -H "Authorization: Bearer $FETCHER_API_KEY" \
  --data-urlencode "query=ai agents min_faves:500 -filter:replies" -G \
  --data-urlencode "sort=Top" \
  "https://twitter.fetcher.sh/api/search"

Search accounts by name:

curl -H "Authorization: Bearer $FETCHER_API_KEY" \
  --data-urlencode "query=climate scientist" -G \
  "https://twitter.fetcher.sh/api/search/users"

Resolve a profile by handle, then pull its bio/about:

curl -H "Authorization: Bearer $FETCHER_API_KEY" \
  "https://twitter.fetcher.sh/api/handle/nasa"

curl -H "Authorization: Bearer $FETCHER_API_KEY" \
  "https://twitter.fetcher.sh/api/handle/nasa/about"

A user's posts, replies, followers, or followings (by numeric ID from the handle lookup above):

curl -H "Authorization: Bearer $FETCHER_API_KEY" \
  "https://twitter.fetcher.sh/api/user/11348282/tweets"

curl -H "Authorization: Bearer $FETCHER_API_KEY" \
  "https://twitter.fetcher.sh/api/user/11348282/followers"

A single post, its replies, and who reposted it:

curl -H "Authorization: Bearer $FETCHER_API_KEY" \
  "https://twitter.fetcher.sh/api/tweet/1234567890123456789"

curl -H "Authorization: Bearer $FETCHER_API_KEY" \
  "https://twitter.fetcher.sh/api/tweet/1234567890123456789/replies"

curl -H "Authorization: Bearer $FETCHER_API_KEY" \
  "https://twitter.fetcher.sh/api/tweet/1234567890123456789/retweeters"

An X List's members and posts:

curl -H "Authorization: Bearer $FETCHER_API_KEY" \
  "https://twitter.fetcher.sh/api/list/1234567890/members"

curl -H "Authorization: Bearer $FETCHER_API_KEY" \
  "https://twitter.fetcher.sh/api/list/1234567890/tweets"

Trending topics for a country:

curl -H "Authorization: Bearer $FETCHER_API_KEY" \
  "https://twitter.fetcher.sh/api/trends?country=United%20States"

MCP

  "mcpServers": {
    "x": {

Free: search_endpoints, describe_endpoint, check_balance. Paid: fetch_data (any endpoint above), topup_credits, plus the named shortcut twitter_search. Drop the headers block to pay per call with x402 instead — see the fetcher skill for the full flow.

Errors

• 400 — missing/invalid parameter (message names it)
• 401 — unknown or rotated key
• 402 — payment required (x402 challenge) or topup_required (credits exhausted)
• 404 — not a priced path
• No rate limits; no refunds on upstream failures (settlement precedes delivery)
