Agent & Infrastructure

World ID Proof Verifier: Verify a World ID 4.0 proof via the Worldcoin Developer Portal API. Generates an RP signature server-side, then proxies the full IDKit proof to developer.world.org. Returns { valid, nullifier, worldcoin_response }. Pay per call in USDC on Base via x402 — POST https://x402.freeq.one/tools/verify_worldid.

A selection nobody can rig, including us. Seeded by the drand League of Entropy beacon: a distributed network emits one signed value every 30 seconds and no participant, Soren included, can choose or predict it. Returns the winners, the round, and the exact derivation so anyone can recompute the result. Name a FUTURE round with round= to remove even the assumption that we did not wait for a beacon we liked.

BAGS Agent API index — machine-readable directory of the agentic payment API, MCP server, and x402 payment surface.

Fetch any URL and, without paying, decode its x402 402 Payment Required challenge: price (atomic and formatted for known stablecoins), asset, network, payTo, resource, description, timeout and any input schema. Flags MPP and Bazaar discovery extensions. Returns free:true when no payment is needed. SSRF-hardened: public hosts only; private, loopback, link-local and cloud-metadata addresses are rejected.

Consolidated x402 launch audit: probe suite (HTTP, TLS, DNS, RDAP, A2A, OpenAPI, paid routes) plus the Coinbase x402 validator verdict on Bazaar eligibility and an AI-written remediation plan. Score, findings, evidence, signed receipt. / Auditoría de lanzamiento x402 consolidada: sondas deterministas más el veredicto del validador de Coinbase de elegibilidad en el Bazaar y plan de remediación con IA. Puntuación, hallazgos, evidencia y recibo firmado.

Rank live autonomous-agent work from Taskmarket and Task-Bounty by expected value, competition, deadline, skill fit, and entry cost. Call before picking which task to attempt.

Tiered payment receipt (tier 2): pay once with x402 and get back a short-lived receipt token that /pay/verify checks for you. The tier is fixed by the path - you do not send it. Optional ?ref= carries your own opaque reference, such as a query hash, straight through to the receipt. This mints a receipt rather than returning data, so there is no lookup that can come back empty. $0.03 per call.

Subscribe an email to the ForgeMesh Brief — event-driven x402 ecosystem intelligence for agent operators, measured from 800+ live listings. Issues only when something materially changes: catalog purges, silently changed discovery APIs, undocumented limits that delist sellers. Use it to: subscribe your operator to x402 seller intel, get alerted when the discovery layer shifts, follow agent-economy infrastructure news. $0.001 anti-spam price; unsubscribe link in every issue.

Run an agent security and AI discovery readiness audit for a public site, checking the manifests and files agents use to discover, understand, and purchase. Returns a deterministic score, evidence, and repair recommendations.

Why an x402 endpoint fails to charge or appear in the Bazaar: verifies the 402 (version, CAIP-2 network, currency, payTo, amount, window) and the discovery listing without paying. Score, findings with fixes, signed receipt. / Por qué un endpoint x402 no cobra o no aparece en el Bazaar: verifica el 402 (versión, red CAIP-2, moneda, destino, importe, ventana) y la ficha de discovery sin pagar. Puntuación, hallazgos con arreglo y recibo firmado.

Unblocker for AI agents: send {url} and get the page back as clean Markdown, with title, description, language, final URL and HTTP status. Gets through Cloudflare and other common bot protection and can render JavaScript-heavy pages. Set format to html or text for those instead. A page that can't be fetched (blocked, error status or empty) is not charged. No API key, proxy or account: pay per call in USDC over x402 (Base, Polygon) or MPP (Base).

Text embeddings API without an API key: up to 64 texts per call, 768-dimension embedding vectors computed on our own hardware. For semantic search, clustering, dedup, and RAG. Pay per call with USDC over x402; inputs never stored.

Daily history facts API: retrieves notable historical events tied to any calendar date, each entry carrying the year, a one-line summary, and a link for further reading. Built to be called once a day as a rotating content source. Useful for calendar apps, morning-briefing bots, and educational trivia agents. Attribution required and included.

Official $0.01 proof-of-life resource for SpendTheBits x402: returns a JSON heartbeat. Pay it to verify your agent's x402 client end to end.

MIDAX402: Evidence+ x402 intelligence with expanded corpus retrieval, local risk brief, contradiction scan and concrete action plan. We do not grade our own answer: the verdict is answered or needs_more_data (grounded in the corpus or not); evidence_grade (thin/moderate/broad) grades that evidence, auditable via retrieved_corpus_ids. confidence_score is DEPRECATED, still served as a band projection.

Call Open-Meteo weather through our metered gateway: our rate-limit budget and a 60s cache absorb your polling, so your loop never sees a 429. Inputs: path (upstream path, e.g. /ping) and q (raw query string). Returns the upstream JSON under 'data'.

Call Binance spot market data through our metered gateway: our rate-limit budget and a 5s cache absorb your polling, so your loop never sees a 429. Inputs: path (upstream path, e.g. /ping) and q (raw query string). Returns the upstream JSON under 'data'.

A2A (Agent2Agent) protocol JSON-RPC endpoint, SendMessage only. Authorizes up to $0.75 (the highest-priced skill); settlement charges the invoked skill's real per-skill price. Base (EVM) only -- for Solana use the REST or MCP endpoints. See /.well-known/agent-card.json for the skill catalog and per-skill pricing.

Describes what is in an image in about one second: pass an https URL or base64 and ask anything about it, from a one-line caption to reading a sign. Pairs with the rest of the chain: describe an image, translate the description, then have it read aloud. You are only charged if the description is delivered. No API key, no account.

Generate strong random secrets from the platform CSPRNG, with the entropy in bits so you can judge them. Four alphabets, including one with no look-alike characters for anything a human has to read back.

Flip one or more fair coins and get heads or tails, with the tally. Cryptographically random, not Math.random. For tie-breaks and A/B splits an agent has to decide on its own.

Vet an x402 seller before integrating: how many resources the domain lists, its 30-day call volume, its best-adopted endpoint, its price range (min/median/max USDC per call), and its most-used endpoints. The aggregates cover the whole daily Bazaar sweep, so 'not listed' means the domain offers nothing in it at all. The endpoint list is served from the searchable slice instead; resources_servable and resources_complete say how much of the domain that list reaches, before you read it.

What just launched in the x402 economy: the most recently listed or reindexed Bazaar resources, newest first, with price and adoption stats. Track new competitors or spot fresh capabilities to consume. The feed draws from a bounded pool of the newest listings and `listed_at` is the Bazaar's re-index stamp, so check `window_complete` and `corpus.covers_since` for the window your answer actually covers — both are free on the catalog listing.
