Look up all x402 Bazaar resources listed under a merchant payTo wallet.

Structured extraction: give a JSON Schema plus a URL or raw text, get back JSON matching the schema.

OpenAI-compatible text embeddings API (alias of /v1/embeddings for api/v1-style base URLs) — input as a string or batch of up to 128 strings, model text-embedding-3-small (default) or text-embedding-3-large. Flat $0.005 per call in USDC via x402, no OpenAI account or API key.

OpenAI-compatible chat completions gateway — standard /v1/chat/completions path and request shape, model chosen in the body: any gpt-* chat model (not Claude/embeddings), each at its own price. Priced per model, $0.005–$0.65 per call in USDC via x402, no API key: POST unpaid and the 402 quotes your model's exact price. Supports response_format json_object. GET /v1/models (free) lists every model with its endpoint and price.

Real-time local business and places search for AI agents. Find restaurants, coffee shops, stores, services, and nearby businesses with structured names, addresses, coordinates, ratings, categories, phone numbers, and websites where available.

Before your agent onboards, pays, or contracts with a counterparty: screen the name against the U.S. Treasury OFAC sanctions lists (SDN + Consolidated non-SDN, synced every 6h) for $0.01. Benchmarked 114/114 sanctioned names found with zero false positives on a 152-case adversarial corpus of misspellings, word-order swaps, and transliterated aliases. Ranked candidates with confidence 0-100, program tags, and match evidence. Assistive screening signal, not a certified compliance determination.

Search the public web and return normalized, source-neutral results with titles, URLs, domains, snippets, freshness controls, and strict result caps for agent research workflows.

Zip key and value lists into an object. Call when you rebuild maps from parallel agent arrays. Returns object and count for $0.001 USDC via x402 on Base. No network, no keys, no retention; first-party local JSON only. Results are advisory; the caller owns budgets, auth, and production controls.

Look up HTTP status-code meanings for $0.001 USDC or retrieve the common-code reference. Call when you need this bounded result without an API key or subscription. Returns machine-readable JSON via x402 on Base or Solana. Limitation: results cover only the supplied input or one bounded public endpoint at request time; callers must verify before acting.

Compound a list of period returns into a total growth factor. Call when multi-period performance rollups from return series you already have. Returns compounded factor and total return as deterministic JSON for $0.001 USDC via x402 on Base. First-party local math only—no RPC, live market feed, API keys, storage, or mediagen. Advisory only; the caller owns capital, risk, and production controls.

OpenAI-compatible chat completions over x402, answered by Claude Sonnet 4.6 — send a messages array and get an assistant reply for Q&A, reasoning, agent planning, coding help, summarization, extraction, and classification. OpenAI chat.completions body and response. Vision: up to 4 https image_url parts. Flat $0.06; input ~24KB (each image counts 1,600 tokens), max_tokens 1024; no streaming.

Historical price series for an asset slug (capped data points).

Five minute open interest history for the major perpetuals in base units and USD, normalised across symbols and retained on our side, so one query replaces per-symbol paginated pulls against exchange endpoints.

Cross-class positioning panels per asset — futures funding stress, options 1M risk-reversal skew, order-book imbalance, and 7-day taker buy/sell ratio. Each panel: current z, percentile, 30-day sparkline, one-line narrative. Response carries a _next block with active-signals / thesis / regime-context / top-setups / peer-cluster so an agent can go from positioning read to per-asset conviction, historical edge, or basket construction without leaving the flow. Coverage: pass any asset in the CRYPTYX 200+ tracked universe (BTC, ETH, SOL, top-cap + long-tail).

Reloadpi — Order status and refund schema. Returns the fulfillment state machine, polling URL, and refund endpoint for any paid order.

Recovers the address that signed a personal_sign (EIP-191) message and tells you whether it matches the address you expected. This is how you prove a wallet is controlled by whoever is talking to you.

Shuffle a list into a uniformly random order with Fisher-Yates over the platform CSPRNG. Every permutation is equally likely, which sorting by a random key does not give you.

Checks one IPv4 address against nine public DNS blocklists at once — SpamCop, UCEPROTECT, PSBL, Barracuda, DroneBL and four more — and returns each list's raw return code plus the reason text the list itself publishes, not a score. Every list is re-checked on each call with its RFC 5782 test entry, so a dead list or one that refuses queries comes back as unavailable instead of reading as clean. Includes the delisting URL for each hit.
