Agent & Infrastructure

OpenAI-compatible text-to-speech over x402 - point any OpenAI SDK's audio.speech.create() at base_url https://agent402.tools/v1 and pay $0.06 per call in USDC, no API key, no signup. Served by Voxtral Mini TTS behind a five-model failover chain (xAI Grok Voice, Kokoro, MAI-Voice-2 Flash, MAI-Voice-2), every link proven by a real paid canary - a provider outage never becomes your failure. Up to 2,000 chars in, raw mp3 (default) or pcm bytes out - the same wire shape as OpenAI's endpoint.

Returns network-wide totals: total x402 events, service count, and a UA classification breakdown (agent vs browser vs bot). Use it to benchmark your service's agent-traffic share against the network.

Returns MetaLend API services directory with a one-line summary of each RebalancerResource endpoint plus links to API docs.

Pre-trade risk check for AI agents trading crypto: live orderbook slippage at YOUR size, side-aware funding carry, open-interest crowding, and optional contract security — composed into a single ok/caution/avoid verdict with per-factor reasons and raw data embedded. Answers 'is this trade sane?' before trading, not after. Replaces four API integrations plus the judgment layer.

Pay-per-Proof: one post-quantum ML-DSA-65 / Dilithium-3 (NIST FIPS 204) signature over your message/hash, x402-native.

Otto X402 Router — Meta Intelligence. Ask what data/service you need; get the best Otto-verified plus live CDP Bazaar x402 candidates with prices, pay_urls and blunt source labels. Non-custodial discovery.

PhoneAgent — full directory of services with rentable SMS phone numbers for AI agents. Returns 1,000+ service aliases: Telegram, WhatsApp, Google, Facebook, Instagram, Twitter/X, Discord, Apple, PayPal, OpenAI/ChatGPT, Claude, plus crypto/Web3 onboarding (Alchemy, Coinbase, Binance, Bybit, OKX, Kraken, Robinhood, ...). Use `other` for any platform not separately listed. Each entry shows the alias to pass to POST /rent and the cheapest price tier ($1, $2, or $5 USDC). Add ?country=<iso> (e.g.

PhoneAgent — countries with rentable SMS phone numbers for AI agents. Returns 190+ supported countries, each with the number of services offered and the cheapest price tier ($1, $2, or $5 USDC). Add ?service=<alias> (e.g. tg, wa, go, zo for OpenAI, other for any platform) to see which countries carry that service with live price and inventory pool. Companion route GET /services lists all 1,000+ service aliases; GET /services?country=<iso> lists what a single country offers. Pair with POST /rent

Use when an agent needs bazaar delta. Returns x402 Bazaar day-over-day catalogue diff between the two latest daily full-catalogue snapshots: counts and samples of added resources, removed resources, and price changes (from/to atomic amounts). $0.004.

Put one question to a panel of 3 different AI models and get a single verdict back. Each model answers independently, then a chair synthesizes: verdict, confidence, the points they all agreed on, the dissent, and what would flip the answer. Use it for judgement calls where one model's opinion is not enough: is this safe, is this worth it, which option. No account, no API key, one USDC micropayment per call.

One post-quantum-signed AI decision attestation, anchored to Hedera mainnet HCS. Send {agentId, data}; receive {attestationId, verifyUrl, settlement}. ML-DSA-65 (FIPS 204) signature, free public verification. Payment verified before mint, settled after — a failed mint is never charged. Audit-ready evidence.

OpenAI's own transcription wire: POST multipart/form-data with a `file` part and get the transcript back. Point any Whisper-shaped SDK at this gateway and pay per call with USDC, no account and no API key. Same model and same four-minute cap as /api/transcribe, which takes a URL instead of an upload; /v1/pro/audio/transcriptions takes it to ten minutes.

OpenAI-compatible chat completions GROUNDED in a live web search on every call: the gateway runs an Exa search (up to 5 results) for the prompt, hands the results to the model, and returns the answer with url_citation annotations - $0.03 per call in USDC, no API key, no signup. Model is chosen server-side like the auto tier (omit "model" or send "auto"; explicit ranked models accepted); the response adds agent402_router {category, quality, served}.

x402 payability check: reachable + well-formed 402 + (Solana) destination-ATA existence

Search x402 service registry — broad q search plus health, score, category, tag, and tags filters

Use when an agent needs x402 facilitator health. Returns Live health probe of the two most-used x402 facilitators: supported kinds, schemes and networks from one, reachability with HTTP status and latency from the other (the one this service settles through on Base and Solana). $0.003.

Use when an agent asks if a contract is an upgradeable proxy and where its code is. Returns the standard (EIP-1967, beacon, UUPS, minimal, legacy, Safe, none), implementation, admin, beacon, slots and block read on Base, Ethereum, Optimism, Arbitrum or Polygon; 4 extra slots decoded. $0.003.

Use when an agent needs bazaar listing lint. Returns Quality-score an x402 Bazaar listing (0-100): live SSRF-guarded probe of the resource for a valid 402 challenge with description/output-schema/category/price-floor checks, plus snapshot-history analysis from daily full-catalogue Bazaar snapshots (price churn, delisting). $0.01.

$0.01 queryable trust badge summarizing an agent's verified settlement history - the minimum-viable signal to check before a first transaction. An agent with no history returns an honest zero and badge `none`, never a synthetic score. | BlindOracle by Craig M. Brown (craigmbrown.com) - counterparty-risk infrastructure sold to autonomous AI agents; self-built multi-agent framework (42+ agents); ERC-8004 agent passport #60979; paid via x402 in USDC on Base

Notarize AI output: a signed Ed25519 attestation of the model response plus sha256 content hash, receipt token, and Merkle anchor status for one AI inference — a cryptographic receipt for inference that lets you prove an AI said X and verify model output authenticity, checkable free by anyone, anytime.

Historical hourly AI intelligence digests (1-24 hours lookback). Track how AI agent sentiment, topics, and narratives evolve over time. Each digest contains full analysis of that hour's agent activity.

Agent payments have no chargeback. Paddock is pre-payment verification for AI agents. get_token_metrics returns Paddock's own daily series by metric and date range: spend share, daily transactions, category concentration, new services, liveness score.

Signed, ledger-derived trust evidence about a NAMED BlindOracle agent (pass the agent name or erc8004 id as `subject`): passport status, audit-report count (ProofOfAuditReport 30105), dispute record, settlement-proof attestations, and revocation flags - each field read fro... | BlindOracle by Craig M.

Entry point to the x402 Carbon Retirement API on Base. Returns every endpoint you need plus a live snapshot of the top 3 carbon classes and marketplace listings by liquidity. Discover, quote and certificate are free. Retiring is paid: each retirement costs the credit price plus a fee, sent from your own wallet (prepare/retire) or relayed from a signed USDC authorization (prepare-auth + POST actions/retire).
