A paid sandbox for x402 clients. Pay $0.10 and receive your own settled payment back — payer address, amount, network and settlement transaction — so a test can assert your 402, sign, retry and settle loop works against a live facilitator. Scenario parameters exercise the failure paths for free: prove your max-price guard fires, that you abandon an expired quote, handle a rejected payment, and retry a failed settlement.

Claim grounding and citation attestation for AI agents: verified enrichment that adds a veracity field to text. Each factual claim is grounded against live web sources (Wikipedia + world news) and returned with a machine-verified verdict (supported/refuted/unverified), a confidence score, and cited sources. Refuses to guess on conflicting evidence. Built for research agents that must cite, citation-locked content, and compliance checks.

Audio transcription API for agents: paid per call, no keys, no accounts. Neural speech-recognition transcript of any public audio URL up to 25MB, with segment text. Nothing retained.

Audio transcription API: transcribe any public audio URL (mp3, wav, m4a, ogg — up to 25MB / ~20 min) to text with a neural speech-recognition engine running locally on our hardware. Multilingual (~99 languages), auto language detection. Use as a speech-to-text step for voicemail, podcasts, meetings, and voice agents. Audio is processed in a sandbox and deleted immediately; we keep nothing.

Resolve the site's IP and check it against 15 major DNSBL spam/abuse blacklists. Use before sending mail from, or trusting, a host. WARN = listed on 1–2 lists; DOWN = listed on 3 or more.

Load the full page and measure time-to-first-byte, total load time, and downloaded size (capped at 5 MB). Use to gauge front-end performance before crawling, embedding, or depending on a page.

Confirm a funded crypto off-ramp transfer (USDC to bank). Submit the transfer_id from /transfer and the on-chain tx_hash of your USDC deposit; the fiat bank payout then proceeds. Idempotent. Pay 0.01 USDC.

Top Polymarket wallets over a 7d or 30d window, ranked by EDGE, not by raw win rate. Win rate is computed from RESOLVED markets only (a trade wins when its side matches the final resolution), but ranking a wallet by win rate alone rewards backing favourites — winning a bet the market prices at 0.99 shows no skill. So wallets are ordered by edge_lower_bound = (Wilson-95%-lower-bound of win_rate) − avg_entry_price: how far the wallet beat the price it paid, damped so a tiny perfect record can't top a large one. Final ranking is by conviction_score = edge_lower_bound × ln(1 + total_volume_usd), scaling proven edge by the capital behind it (a real edge on $200k outranks the same edge on $6k), with log diminishing returns so size alone can't buy the top. Rankable wallets need >= 10 trades AND >= $1000 total volume in the window (a skin-in-the-game floor — cent-sized longshot bets otherwise manufacture a real-looking edge) plus at least one decided trade. Each entry: address, Predge score (0-100 or null), win_rate, avg_entry_price, edge, win_rate_lower_bound, edge_lower_bound, conviction_score, decided_trades, trades_count, total_volume_usd, avg_position_usd. Honest degradation: {"insufficient_data": true, "reason": ...} when the dataset is too young. Query params: window (7d|30d, default 30d), limit (1-100, default 50).
