• POST/api/time-convert—No price listedConvert between epoch (s or ms), ISO 8601, and any IANA timezone. Give a value (epoch seconds or milliseconds, an ISO string, or 'now'), get every representation back: utc, epochSeconds, epochMillis and, with tz, timezone, localIso (ISO 8601 with the zone's offset, e.g. 2026-06-11T19:00:00+09:00), utcOffset and local (a display string). A bare number under 1e12 is read as seconds, otherwise as milliseconds. Also on x402 Bazaar
• POST/api/fc-cast-metrics—No price listedCast volume over time for a search query: how many Farcaster casts matched per bucket across the last 1d, 7d, 30d, 90d or 180d (hourly or daily buckets), optionally limited to one author or channel, plus the total. Cached 60 s. Use to chart mention volume for a token, product or event and detect spikes. Also on x402 Bazaar
• POST/api/skill/tx-forensics—No price listedExplain what an EVM transaction actually did: confirmation status, the raw transaction from the chain, decoded calldata with typed parameters, the resolved function signature, and labeled counterparties. Transaction forensics skill pack: one x402 payment runs 5 underlying tools (tx-status, evm-rpc, calldata-decode, selector-lookup, address-label); partial-success per step. Also on x402 Bazaar
• POST/api/polymarket-market—No price listed
• POST/api/csv-to-json—No price listedParse CSV (quoted fields supported) into a JSON array of objects, using the first row as headers (header=false for arrays). Also on x402 Bazaar

• GET/api/fred-search—No price listedFull-text search across FRED's ~800,000 economic time series. Returns series IDs (use with /api/fred-series), titles, frequency, units, and a popularity score. Also on x402 Bazaar
• POST/api/sol-token-lookup—No price listedResolve a Solana token by mint, ticker or name through a Solana DEX aggregator's token index and get its profile in one read: name, symbol, decimals, price, market cap, FDV, liquidity, holder count, circulating and total supply, verified flag, organic score (the aggregator's wash-trade-resistant activity score), tags, launchpad, dev wallet, first pool and date, audit facts (mint and freeze authority disabled, top-holder share, dev mints) and 24h stats (price, holder and liquidity change. Also on x402 Bazaar
• POST/api/gravatar-check—No price listedCheck whether an email address has a Gravatar: hashes the normalized email (MD5, pure CPU - the raw address is never sent upstream), probes gravatar.com for an avatar, and fetches the public profile when one exists (display name, username, profile URL). Accepts a raw email or a precomputed MD5/SHA-256 hash. Signal-only: a Gravatar's existence suggests a real, web-active address but does NOT verify identity or deliverability - pair with /api/email-validate for MX checks. Also on x402 Bazaar
• POST/api/age—No price listedCompute a precise age (years, months, days) from a birth date to today (or a given date), plus total days. Also on x402 Bazaar

• POST/api/code-run—No price listedExecute Python or JavaScript code in a secure, isolated cloud sandbox. Returns stdout, stderr, and the expression result. No setup needed; pay per call via x402. 30s timeout, 10k char code limit. A run that hits the time limit is returned with timedOut: true and the output it printed, and is charged. Also on x402 Bazaar
• POST/api/event-logs—No price listedFetch contract event logs (eth_getLogs) on Ethereum, Base, Polygon, Arbitrum, or Optimism - bounded so it always answers: block range capped at 2000 blocks (default: the last 100, auto-narrowed for busy contracts), at most 200 logs returned (truncated flag set if more matched). Filter by contract address and optional topic0 (event signature hash). Keyless multi-endpoint failover. Also on x402 Bazaar
• POST/v1/images/pro—No price listedHigher-fidelity text-to-image on the OpenAI images wire: a prompt in, one 1024x1024 image out as inline base64, served by a pro-grade diffusion model in about ten seconds. Use it when an agent needs a finished picture for a page, a post or a product and quality matters more than the cheapest draft. Also on x402 Bazaar
• POST/api/llm—No price listedLLM inference proxy - send an OpenAI-format chat/completions request and get a response from GPT-4o-mini (or gpt-6-luna by its id). Supports vision (up to 2 image URLs, low detail) and structured output (response_format: json_object or json_schema). No API key needed; pay per call via x402. Input capped at 16k chars, output at 4096 tokens. Also on x402 Bazaar

• GET/api/crypto-orderbook—No price listedL2 order-book snapshot for a spot pair: best bid/ask, mid price, spread (absolute + %), and the top N aggregated price levels per side (default 25, max 100). Pairs use BASE-QUOTE format (BTC-USD, ETH-USD, SOL-USDC). Read from a U.S. spot exchange's public market-data API - keyless; coverage is that exchange's listed markets. Also on x402 Bazaar
• POST/api/eas-attestations—No price listedList EAS (Ethereum Attestation Service) attestations for an address as recipient, attester, or either, on mainnet/Base/Optimism/Arbitrum/Sepolia. Returns attestation id, attester, recipient, schema id, revocable/revoked flags, timestamp, and decoded data JSON. Use to verify Gitcoin Passport stamps, Coinbase verifications, KYC attestations, or any other on-chain claim about an address. Also on x402 Bazaar
• GET/api/edgar-company-concept—No price listedFull reported history of a single XBRL concept for one company (e.g. quarterly Revenues for Apple).

• POST/api/brotli-compress—No price listedCompress a string with Brotli (RFC 7932) and return it as base64. Brotli typically beats gzip by 15-25% on text - useful when bytes matter (e.g. cramming context into an LLM prompt, fitting under a transport cap). Slower than gzip; pick gzip if speed matters more than ratio. Also on x402 Bazaar
• GET/api/timezone-convert—No price listedConvert a datetime from one IANA timezone to another. Accepts ISO 8601, Unix timestamps (seconds or milliseconds), or natural date strings. Returns the converted time in both timezones with UTC offset. Also on x402 Bazaar

Also on x402 Bazaar
• POST/api/cert-transparency—No price listedSearch public Certificate Transparency logs for every cert issued to a domain. Two independent public CT search services are queried, the second only if the first is slow or fails, and `source` names the one that answered (their coverage windows differ). Returns the cert list plus a deduped subdomain set extracted from the SANs - the fastest way to enumerate subdomains for a security audit. No key required. Also on x402 Bazaar
• POST/api/loan-payment—No price listedCompute the monthly (or per-period) payment on a fully-amortizing loan: mortgage, auto, student loan, business loan. Returns the periodic payment, total paid over the term, and total interest. Matches Excel's PMT(rate, nper, -principal).
