Resolve requested product options to a canonical public variant when the provider exposes them. Ambiguous or missing options are reported explicitly; no checkout or cart mutation occurs. Base mainnet USDC

Return a normalized current offer price for a public product or listing. Provider fields missing from the source remain null; no price prediction, purchase or customer authentication is performed. Base mainnet USDC

Check an anonymously readable OCI image tag and resolve its manifest digest through the standard Distribution API. No blob pull, push, delete or private registry access is performed. Base mainnet USDC

Did my agent overpay for x402 APIs? The wallet overspend audit reads a buyer wallet's USDC payments on Base and checks each against the payee's listed Bazaar price: payments above the listed price, oversize settlements of 10x or more, and payments to addresses with no listing, totalled per seller. Use when an agent or its operator needs a spend audit of an x402 buyer wallet.

Extract public SKU, GTIN, UPC, EAN, ISBN, MPN and provider identifiers from a product source. Missing identifiers stay null and are never guessed. Base mainnet USDC

Measure bounded sequential timing samples for one public HTTP endpoint. Samples are hard-capped at three and this is never a load-testing or port-scanning service. Base mainnet USDC

InterAI+ self-service in USDC: hundreds of models, MCP and Skill for chat completions, coding and more. Pick a model from the catalog or let the service pick one for you. Price is shown in the 402 response before payment; failed calls are not charged. Free: GET /v1/catalog, GET /v1/quote, GET /v1/coming, GET /v1/autonomous-agents. Register interest ahead of time with POST /v1/register-interest. Coming: image and video generation, contest for AI agents with rewards.

Check whether a named branch exists in a public GitHub repository and return the branch current head commit SHA and URL without cloning. This is a read-only branch-state lookup; branch protection stays unknown when the public API does not expose it. Base mainnet USDC

Perp funding rates (Hyperliquid, all live markets): current hourly funding, 8h and annualised APR, who pays (longs or shorts), premium vs oracle, mark and oracle price, open interest USD, 24h volume and OI rank, plus top positive and negative funding extremes. Refreshed every 60 s. Optional coin filter (comma list, e.g. coin=BTC,ETH,SOL) and limit.

E-commerce product price + stock lookup: search 180+ public Shopify brand stores (apparel, beauty, electronics accessories, supplements, home, outdoor, jewelry, pets, toys) by product name or SKU. Returns up to 50 matching variants with store, brand, product and variant title, current price, compare-at (list) price and discount %, in-stock flag, product URL, image, first/last seen and a daily 30-day price and stock history with 30-day low/high. Optional domain filter.

Continuous Fair Offer certification for an x402 API: the full certification now, then re-run about once a day for 30 days. The public status and badge show the latest check, so a pass is withdrawn the day a check fails, and every check's signed result is published. One payment, no renewal; a seller pays for the checking, never for the outcome.

Fund the x402 evidence commons: a $0.10 contribution that keeps Agoranome's evidence lookups, Fair Offer checker and buyer policy pack free. Returns a signed receipt; 15% goes to the cause Agoranome pledges to, verifiable at /impact/ledger. Nothing else is delivered, and a contribution never changes a result, a rank or a certification.

402 conformance check for an x402 or MPP API: can buyer agents' SDKs pay it? Checks the x402 v2 requirements (whole-unit amounts, addresses, the token's EIP-712 domain, the same terms on every request), that a malformed payment is refused, any MPP challenge against the paymentauth.org draft, and the live price against the Bazaar and the host's openapi.json. Unpaid requests only; nothing is signed or paid.

Prompt injection detection API for AI agents. Prompt-injection scan for text your AI agent is about to read (web pages, emails, tool output, MCP tool descriptions): risk score 0-100, verdict, categories and exact spans. Detects instruction overrides, jailbreak personas, system-prompt extraction, fake chat delimiters, data-exfiltration URLs, tool hijacking, hidden Unicode and encoded payloads. Deterministic rules, no data stored.

Chat completions via Telnyx Inference (meta-llama/Meta-Llama-3.1-8B-Instruct). OpenAI-compatible. $0.002237 USDC per call.

chainpeek (Tanod) latest block number, timestamp and age in seconds of Ethereum, Base or Robinhood Chain. Use when an agent needs the latest block number of Ethereum, Base or Robinhood Chain, with its timestamp and age in seconds.

Hosted by vAPI for o1.exchange: List tracked launchpad tokens.

New DEX pools on BNB Chain (bsc) or Base from factory PairCreated/PoolCreated events we read on-chain: pool address, DEX (PancakeSwap v2/v3, Uniswap v2/v3, Aerodrome, other forks), new token address/symbol/name, quote token (WBNB/WETH/USDT/USDC), exact creation time and block, age, and volume, buys/sells and liquidity since launch. Params: chain=bsc|base, hours (default 1, max 24), limit.

Forward geocoding for AI agents: turn a place name or address into coordinates. Returns the best-match latitude, longitude, country and ISO country code, administrative regions (admin1/admin2), population, IANA timezone and GeoNames feature code. Query by q= or address=. Sourced from Open-Meteo geocoding — keyless, unified schema, stablecoin-payable.

Pump.fun launches and graduations (Solana): newest pump.fun token launches (mint, name, symbol, creator, metadata URI, launch tx, age), live bonding-curve progress % and SOL in the curve, tokens close to graduating, and tokens whose curve completed (graduated to the PumpSwap AMM) with time. Parsed from pump.fun program logs and curve accounts on-chain; launches are sampled continuously (not every single launch), curves re-read every ~15 min.
