Api x402 offerings

Sigma CAPABILITY_FEED: ranked governed capability intelligence for autonomous agents.

LLM chat completions API, OpenAI-compatible: one endpoint for 100+ models (Claude, GPT, Gemini, Grok, DeepSeek, Qwen), no API key or account, pay per call in USDC. Call it when an agent needs an LLM answer, a second opinion, or a model it has no key for. SingIt Ask; models at GET /v1/models.

Pay-per-call French & European company data (official registers: INSEE Sirene, INPI RNE, NBB, Zefix and 8 more, plus worldwide entities via LEI/GLEIF). Every skill is a paid HTTP resource: send a JSON data part {"path": "/v1/..."} or {"skill": "<id>", "params": {...}}; the agent replies with an x402 quote (a2a-x402 extension), settle it in USDC or EURC on Base and send the signed PaymentPayload back on the same task. No account, no API key. Free text is not interpreted.

Runs a read-only SPARQL query on Wikidata and returns the rows as plain values (ASK returns true or false). Only SELECT and ASK are allowed; updates are refused. A LIMIT of 100 or less is added when missing. 8-second limit. Data is CC0.

Skim: x402 ecosystem feed — new services and price changes across the public x402 registries, as structured items. Refreshed on a 15-minute cycle (stale served if a registry is down); poll as often as you like.

What is this wallet DOING right now? One call summarizes any wallet's recent on-chain activity: net token flows in/out with USD values (accumulating or distributing which tokens), recent transaction methods (swap/transfer/approve), activity level, top counterparties, ETH balance and last-active time. The smart-money / wallet-tracking read copy-trade and whale-watching agents make on wallets surfaced by /crypto/whales — a Nansen-style smart-money profile from free public data. Chains into /crypt

Upcoming and recent Starship launches with status and mission info

Validate an intended paid API request against its declared contract before spending. Returns VALID, INVALID, or UNKNOWN with machine-readable reasons. Target URL is never called.

OpenAI's own transcription wire: POST multipart/form-data with a `file` part and get the transcript back. Point any Whisper-shaped SDK at this gateway and pay per call with USDC, no account and no API key. Same model and same four-minute cap as /api/transcribe, which takes a URL instead of an upload; /v1/pro/audio/transcriptions takes it to ten minutes.

Deep single-game state for one game by its id, normalized to one cited JSON. Give a league and a game_id and get the box-score numbers, the status and period or inning, team totals, statistical leaders and any reported injuries. The richest per-game view, fused from the league API or ESPN.

WHP Standing front-door evaluation (ordinary x402 agents)

Returns Starlink-related data from the /starlink endpoint.

Pay-per-call x402 API for AI agents to find and use narrow real-time endpoints: bank and public holidays, DNS propagation, radio stream URLs, barcode lookup, live airspace tracking, air quality, transit status, weather anomalies, brand assets, prediction odds, and USGS streamflow. No account setup required; pay per request with USDC on Base or Solana.

Purchase a bearer token for Station f(x). One payment unlocks multiple data queries with no per-call settlement. Use Authorization: Bearer <token> on any /economic-data/{category}/{slug} endpoint.

Use when a task needs a paid API and the right x402 endpoint is unknown. Takes the task in a few words (web search, weather forecast, verify an email) and returns the top 1-5 Coinbase Bazaar endpoints ranked by repeat paid use (calls per wallet over 30 days), recency, relevance and price, each checked live, with URL, method, price, network, reasons and risk flags. Optional max_price_usd and limit. Read-only. Errors: 400 bad_input. Failed calls are not charged.

Use this when a question needs several of these tools chained together and a written answer, for example comparing tokens or researching a launcher. Price: $0.541 in USDC on Base, or $0.551224 in USDG or $SWOGE on Robinhood Chain (tool price + settlement cost, minimum $0.02).
