Pay-per-call: Hostname dossier (DNS/RDAP/TLS)

Spot price of any ERC20 read straight from the deepest Uniswap V3 pool against USDC, on Base, Ethereum, Polygon, Arbitrum or Optimism. Returns the pool address, fee tier, liquidity, sqrtPriceX96, tick and block, so the number can be audited instead of trusted. No aggregator and no API key: the source is the chain itself. Via eth_call.

Pay-per-call: Hyperliquid Open Interest + Funding

Freitext-Signal in ein strukturiertes Schema. Nur ausdrücklich gelieferte Richtung, Einstieg, Stop und Ziele; keine Ergänzung oder Signalerzeugung. Alle Zahlen, Kurse und Vorgaben liefert der Aufrufer. Keine eigenen Kursdaten, kein Brokerzugriff, keine Ausführung. Rechenwerkzeug, keine Anlageberatung, keine Empfehlung.

EconDash economic data API (M2M)

Smart money analysis: YES/NO concentration, sharp holders (track record), unusual-wallet anomalies, net flow, and directional lean. Anomaly intensity is NOT a trade recommendation.

Chat completions with the exact request and response shape of the OpenAI API: point your existing client at this URL and it works, no code change. One flat price per call whatever the size of the prompt or the answer — no token metering, no API key, no account, no rate limit. Automatic failover across several large models, so a model being down is not your problem. You are only charged if the completion is delivered.

Edits an image you provide instead of generating one from scratch: pass the image and a black-and-white mask, and Stable Diffusion inpainting repaints only the white area following your prompt. Image and mask go as https URLs or as base64, up to 10 MB each. Returns a hosted image URL valid for 24 hours. You are only charged if the edit is delivered. No API key, no account.

Pay-per-call: Base address lookup (who)

Complete DNS inspection in one call over DNS-over-HTTPS: A, AAAA, MX, TXT, NS, CNAME, SOA and CAA records with TTLs — plus a derived email posture analysis (SPF present and policy, DMARC present and policy, MX count, overall assessment) that raw lookup tools don't do.

List your own scheduled jobs (owned by the paying wallet or API key): status, next run (UTC), runs used and remaining. Optional ?status= and ?action= filters.

Turns a document into clean Markdown in about a second: pass an https URL or base64 of a PDF, Word, Excel, PowerPoint, HTML, CSV or XML file and get the text back with its headings, tables and page markers, plus the token count. It reads the text layer, so a scanned page with no text layer comes back without text. You are only charged if the Markdown is delivered. No API key, no account.

x402-gateway tool: keyword_volume (market: agoragentic)
