Agent & Infrastructure

OnRamperX is a non-custodial value router for agents and humans: fiat<->crypto and cross-chain via one quote interface (Coinbase Onramp v2, Relay, x402). This endpoint returns the router's live capabilities and rail status; use /api/x402/quote for a ranked route. Settlement centers on USDC on Base.

Is this counterparty safe to pay or accept payment from? Screens it against the OFAC sanctions list, then SYBIL-FILTERS its ERC-8004 reputation: reviewers are clustered by funding source, one vote each, so feedback bought from one purse counts once. Returns an explainable 0-100 score, a proceed / hold / block recommendation, and insufficient_data rather than a guess. Free alternative: GET /v1/verify. Trial: 3 free calls/wallet/24h — https://trust-agent.io/v1/trial.

Image search API - live Google Images results for a query, localised by location and language. Returns ranked images with title, direct image URL, source page URL and alt text. A google images / image search api for agents.

Break a User-Agent string into browser, engine, operating system (each with a version) and device type. Unidentifiable components are reported as null.

Ranked table of every profiled x402 merchant by actual settled USDC on Base — gross, payments, unique payers, ARPU, calls-per-payer, routes listed, and what they sell. Crawler and self-funded flows removed.

Deterministic utility operations for agents: sha256/sha512/HMAC hashing, JWT decode, base64 encode/decode, UUID generation, JSON validation, CSV↔JSON, XML→JSON, URL parsing and semver comparison. Sub-millisecond, no external calls.

Lint any x402 endpoint or payment header against the v2 spec and real CDP facilitator behavior: CAIP-2 network ids, atomic amounts, the EIP-712 domain-name trap ('USD Coin' on Base mainnet vs 'USDC' on Sepolia — wrong name = every settlement fails), the extensions echo Coinbase Bazaar requires for indexing, expired authorizations. Findings as error/warning/info with what will actually break. Built by a seller that debugged all of these in production.

Atomic per-agent integer counter (incr/decr/get/set/reset), scoped to the paying wallet. For tallies, quotas, sequence numbers.

Agent morning brief. One paid call returns the last 24 hours of AI pricing changes, new and removed models, service-status incidents, and top news headlines. The endpoint an agent calls on boot.

Live job postings without scraping: company= returns an employer's current openings straight from their official ATS board (Greenhouse, Lever, Ashby, SmartRecruiters) with title, location, department, type and apply URL; query= searches remote-heavy job APIs (Remotive, Arbeitnow) by keyword. Optional location= filter. JSON response. $0.02 USDC per call, pay via x402, no API key.

General LLM completion: send a prompt (optional system role), get an answer. Reason, rewrite, classify, draft or answer. Flat price, input/output capped.

Pad a string to a target width with a fill character — first-party local utility for agent preflight and proven micro-utils expansion. Returns deterministic machine-readable JSON for $0.001 USDC via x402 on Base. Execution is first-party, local-only, stateless, and memory-only with no paid upstream, no input retention, no web search, no live RPC, and no mediagen. Results are advisory; the caller owns authorization, budgets, and production controls.

Search every indexed x402 resource across Coinbase Bazaar, Agent402 and Agentic Market in one call (7k+ tools): name, description, price, seller, network and real usage metrics (calls, unique buyers, settled volume), with per-source freshness data. The meta-tool for agents: find the right paid tool for any task first, then call it.

Agent-to-agent (A2A) call into another node of the swarm: relay a question and get that node's own answer back, priced per call.

Audit any website for AI-agent and AI-crawler readiness: HTTPS, robots.txt and AI bot rules (GPTBot, ClaudeBot, PerplexityBot), llms.txt, sitemap, title/meta, schema.org JSON-LD, security headers. Returns a 0–100 score with failed checks, issues and concrete recommendations.

Your 402 envelope can pass every static check and still not get you paid. We build a real signed payment at your listed price and submit it to the CDP facilitator verify endpoint, which checks signature, requirements and the on-chain transfer simulation. Nothing settles, so no money moves. You get back whether a real payment would be accepted, and if not, the facilitator own reason verbatim. Pass ?url= or ?domain=.

Market intelligence for the x402 ecosystem: search indexed pay-per-call resources, list trending services, inspect a seller wallet, browse categories, measure competition (count, median/min/max price) and see scored opportunities. Built from continuously scanned public x402 discovery indexes.

Cross-venue first sighting: when Telegram first carried this token, when X first did, and the lead between them

x402 payment E2E test endpoint (echoes query). Factual data only; not investment advice.

Who actually pays you, and what else do they buy? We build the payer-to-service map across the whole Bazaar catalog from on-chain settlement, so we can tell you how many distinct agents paid you, how often each returns, and what share of your buyers also pay other x402 services. Pass ?domain=<yours>; omit for the market-wide buyer pool. Individual buyer addresses are never disclosed.

Returns a list of GitHub repositories, likely filtered or analyzed based on specified criteria.

Signed integrity, provenance and freshness receipt for AI-agent JSON

Audio transcription API for agents: paid per call, no keys, no accounts. Neural speech-recognition transcript of any public audio URL up to 25MB, with segment text. Nothing retained.

Returns current or historical cryptocurrency price data.
